filename extensions to call verilog-mode. (verilog-auto, verilog-auto-inst, verilog-faq) (verilog-submit-bug-report): Update author support URLs. (verilog-delete-auto, verilog-auto-inout-module) (verilog-auto-inout-comp, verilog-auto): Add AUTOINOUTCOMP for creating complemented testbench modules. Suggested by Yishay Belkind. (verilog-auto-inst-port, verilog-simplify-range-expression): When verilog-auto-inst-param-value is set, don't require a AUTO_TEMPLATE to expand parameter substitutions. Suggested by Yishay Belkind. (verilog-auto-inst-param-value): Add safe variable. (verilog-re-search-forward, verilog-re-search-backward): Fix returning wrong search results on Emacs 22.1. (verilog-modi-cache-results, verilog-auto): Fix warning message about "toggling font-lock-mode." (verilog-auto): Fix loosing font-lock on errors. (verilog-auto-inst-param-value, verilog-mode-version) (verilog-mode-version-date, verilog-read-inst-param-value) (verilog-auto-inst, verilog-auto-inst-param) (verilog-auto-inst-port, verilog-simplify-range-expression): Allow parameters to be replaced with their values, on the expansion of an AUTOINST with Verilog 2001 style parameter settings. Suggested by David Rogoff. * verilog-mode.el (verilog-beg-block-re-ordered, verilog-calc-1): Better support for the property statement. Sometimes this keyword introduces a statement which requires an endproperty keyword, and sometimes it doesn't, dependening on the work before the property word. If property is prefixed with assert, assume or cover keyword, then the statement is ended with a ';' Otherwise, property is like task or specify, and is followed by some number of statements, which are ended with an endproperty keyword. (electric-verilog-tab): Support Emacs 22.2 style handling of tab in a highlighted region: indent each line in region according to mode. Supply this so it works in XEmacs and older Emacs.

||
;;; Commentary:
|
||
|
||
;; This mode borrows heavily from the Pascal-mode and the cc-mode of Emacs
|
||
|
||
;; USAGE
|
||
;; =====
|
||
|
||
;; A major mode for editing Verilog HDL source code. When you have
|
||
;; entered Verilog mode, you may get more info by pressing C-h m. You
|
||
;; may also get online help describing various functions by: C-h f
|
||
;; <Name of function you want described>
|
||
|
||
;; KNOWN BUGS / BUG REPORTS
|
||
;; =======================
|
||
|
||
;; Verilog is a rapidly evolving language, and hence this mode is
|
||
;; under continuous development. Hence this is beta code, and likely
|
||
;; has bugs. Please report any and all bugs to me at mac@verilog.com.
|
||
;; Please use verilog-submit-bug-report to submit a report; type C-c
|
||
;; C-b to invoke this and as a result I will have a much easier time
|
||
;; of reproducing the bug you find, and hence fixing it.
|
||
|
||
;; INSTALLING THE MODE
|
||
;; ===================
|
||
|
||
;; An older version of this mode may be already installed as a part of
|
||
;; your environment, and one method of updating would be to update
|
||
;; your Emacs environment. Sometimes this is difficult for local
|
||
;; political/control reasons, and hence you can always install a
|
||
;; private copy (or even a shared copy) which overrides the system
|
||
;; default.
|
||
|
||
;; You can get step by step help in installing this file by going to
|
||
;; <http://www.verilog.com/emacs_install.html>
|
||
|
||
;; The short list of installation instructions are: To set up
|
||
;; automatic Verilog mode, put this file in your load path, and put
|
||
;; the following in code (please un comment it first!) in your
|
||
;; .emacs, or in your site's site-load.el
|
||
|
||
; (autoload 'verilog-mode "verilog-mode" "Verilog mode" t )
|
||
; (add-to-list 'auto-mode-alist '("\\.[ds]?v\\'" . verilog-mode))
|
||
|
||
;; If you want to customize Verilog mode to fit your needs better,
|
||
;; you may add these lines (the values of the variables presented
|
||
;; here are the defaults). Note also that if you use an Emacs that
|
||
;; supports custom, it's probably better to use the custom menu to
|
||
;; edit these.
|
||
;;
|
||
;; Be sure to examine at the help for verilog-auto, and the other
|
||
;; verilog-auto-* functions for some major coding time savers.

Use \\[verilog-faq] for a pointer to frequently asked questions.

NEWLINE, TAB indents for Verilog code.
|
||
Delete converts tabs to spaces as it moves back.
|

Supports highlighting.
|

|
||
Turning on Verilog mode calls the value of the variable `verilog-mode-hook'
|
||
with no args, if that value is non-nil.
|
||
|
||
Variables controlling indentation/edit style:
|
||
|
||
variable `verilog-indent-level' (default 3)
|
||
Indentation of Verilog statements with respect to containing block.
|
||
`verilog-indent-level-module' (default 3)
|
||
Absolute indentation of Module level Verilog statements.
|
||
Set to 0 to get initial and always statements lined up
|
||
on the left side of your screen.
|
||
`verilog-indent-level-declaration' (default 3)
|
||
Indentation of declarations with respect to containing block.
|
||
Set to 0 to get them list right under containing block.
|
||
`verilog-indent-level-behavioral' (default 3)
|
||
Indentation of first begin in a task or function block
|
||
Set to 0 to get such code to lined up underneath the task or
|
||
function keyword.
|
||
`verilog-indent-level-directive' (default 1)
|
||
Indentation of `ifdef/`endif blocks.
|
||
`verilog-cexp-indent' (default 1)
|
||
Indentation of Verilog statements broken across lines i.e.:
|
||
if (a)
|
||
begin
|
||
`verilog-case-indent' (default 2)
|
||
Indentation for case statements.
|
||
`verilog-auto-newline' (default nil)
|
||
Non-nil means automatically newline after semicolons and the punctuation
|
||
mark after an end.
|
||
`verilog-auto-indent-on-newline' (default t)
|
||
Non-nil means automatically indent line after newline.
|
||
`verilog-tab-always-indent' (default t)
|
||
Non-nil means TAB in Verilog mode should always reindent the current line,
|
||
regardless of where in the line point is when the TAB command is used.
|
||
`verilog-indent-begin-after-if' (default t)
|
||
Non-nil means to indent begin statements following a preceding
|
||
if, else, while, for and repeat statements, if any. Otherwise,
|
||
the begin is lined up with the preceding token. If t, you get:
|
||
if (a)
|
||
begin // amount of indent based on `verilog-cexp-indent'
|
||
otherwise you get:
|
||
if (a)
|
||
begin
|
||
`verilog-auto-endcomments' (default t)
|
||
Non-nil means a comment /* ... */ is set after the ends which ends
|
||
cases, tasks, functions and modules.
|
||
The type and name of the object will be set between the braces.
|
||
`verilog-minimum-comment-distance' (default 10)
|
||
Minimum distance (in lines) between begin and end required before a comment
|
||
will be inserted. Setting this variable to zero results in every
|
||
end acquiring a comment; the default avoids too many redundant
|
||
comments in tight quarters.
|
||
`verilog-auto-lineup' (default `(all))
|
||
List of contexts where auto lineup of code should be done.
|
||
|
||
Variables controlling other actions:
|
||
|
||
`verilog-linter' (default surelint)
|
||
Unix program to call to run the lint checker. This is the default
|
||
command for \\[compile-command] and \\[verilog-auto-save-compile].
|
||
|
||
See \\[customize] for the complete list of variables.

If the filename is provided, `verilog-library-flags' will be used to

resolve it. If optional RECURSE is non-nil, recurse through `includes.
|
||
|
||
Parameters must be simple assignments to constants, or have their own
|
||
\"parameter\" label rather than a list of parameters. Thus:
|
||
|
||
parameter X = 5, Y = 10; // Ok
|
||
parameter X = {1'b1, 2'h2}; // Ok
|
||
parameter X = {1'b1, 2'h2}, Y = 10; // Bad, make into 2 parameter lines
|
||
|
||
Defines must be simple text substitutions, one on a line, starting
|
||
at the beginning of the line. Any ifdefs or multiline comments around the
|
||
define are ignored.
|
||
|
||
Defines are stored inside Emacs variables using the name vh-{definename}.
|
||
|
||
This function is useful for setting vh-* variables. The file variables
|
||
feature can be used to set defines that `verilog-mode' can see; put at the

*END* of your file something like:
|

|
||
// Local Variables:
|
||
// vh-macro:\"macro_definition\"
|
||
// End:
|
||
|
||
If macros are defined earlier in the same file and you want their values,
|
||
you can read them automatically (provided `enable-local-eval' is on):
|
||
|
||
// Local Variables:
|
||
// eval:(verilog-read-defines)
|
||
// eval:(verilog-read-defines \"group_standard_includes.v\")

Note these are only read when the file is first visited, you must use

any ifdefs or complicated expressions before the AUTOARG you will need

Limitations:
|
||
Module names must be resolvable to filenames by adding a
|
||
`verilog-library-extensions', and being found in the same directory, or
|
||
by changing the variable `verilog-library-flags' or
|
||
`verilog-library-directories'. Macros `modname are translated through the
|
||
vh-{name} Emacs variable, if that is not found, it just ignores the `.
|
||
|
||
In templates you must have one signal per line, ending in a ), or ));,
|
||
and have proper () nesting, including a final ); to end the template.
|
||
|
||
Typedefs must match `verilog-typedef-regexp', which is disabled by default.
|
||
|
||
SystemVerilog multidimensional input/output has only experimental support.
|
||
|
||
Parameters referenced by the instantiation will remain symbolic, unless
|
||
`verilog-auto-inst-param-value' is set.
|
||
|
||
For example, first take the submodule InstModule.v:
|
||
|
||
module InstModule (o,i)
|
||
output [31:0] o;
|
||
input i;
|
||
wire [31:0] o = {32{i}};
|
||
endmodule
|
||
|
||
This is then used in a upper level module:
|
||
|
||
module ExampInst (o,i)
|
||
output o;
|
||
input i;
|
||
InstModule instName
|
||
(/*AUTOINST*/);
|
||
endmodule
|
||
|
||
Typing \\[verilog-auto] will make this into:
|
||
|
||
module ExampInst (o,i)
|
||
output o;
|
||
input i;
|
||
InstModule instName
|
||
(/*AUTOINST*/
|
||
// Outputs
|
||
.ov (ov[31:0]),
|
||
// Inputs
|
||
.i (i));
|
||
endmodule
|
||
|
||
Where the list of inputs and outputs came from the inst module.
|
||
|
||
Exceptions:
|
||
|
||
Unless you are instantiating a module multiple times, or the module is
|
||
something trivial like an adder, DO NOT CHANGE SIGNAL NAMES ACROSS HIERARCHY.
|
||
It just makes for unmaintainable code. To sanitize signal names, try
|
||
vrename from http://www.veripool.org.
|
||
|
||
When you need to violate this suggestion there are two ways to list
|
||
exceptions, placing them before the AUTOINST, or using templates.
|
||
|
||
Any ports defined before the /*AUTOINST*/ are not included in the list of
|
||
automatics. This is similar to making a template as described below, but
|
||
is restricted to simple connections just like you normally make. Also note
|
||
that any signals before the AUTOINST will only be picked up by AUTOWIRE if
|
||
you have the appropriate // Input or // Output comment, and exactly the
|
||
same line formatting as AUTOINST itself uses.
|
||
|
||
InstModule instName
|
||
(// Inputs
|
||
.i (my_i_dont_mess_with_it),
|
||
/*AUTOINST*/
|
||
// Outputs
|
||
.ov (ov[31:0]));
|
||
|
||
|
||
Templates:
|
||
|
||
For multiple instantiations based upon a single template, create a
|
||
commented out template:
|
||
|
||
/* InstModule AUTO_TEMPLATE (
|
||
.sig3 (sigz[]),
|
||
);
|
||
*/
|
||
|
||
Templates go ABOVE the instantiation(s). When an instantiation is
|
||
expanded `verilog-mode' simply searches up for the closest template.
|
||
Thus you can have multiple templates for the same module, just alternate
|
||
between the template for an instantiation and the instantiation itself.
|
||
|
||
The module name must be the same as the name of the module in the
|
||
instantiation name, and the code \"AUTO_TEMPLATE\" must be in these exact
|
||
words and capitalized. Only signals that must be different for each
|
||
instantiation need to be listed.
|
||
|
||
Inside a template, a [] in a connection name (with nothing else inside
|
||
the brackets) will be replaced by the same bus subscript as it is being
|
||
connected to, or the [] will be removed if it is a single bit signal.
|
||
Generally it is a good idea to do this for all connections in a template,
|
||
as then they will work for any width signal, and with AUTOWIRE. See
|
||
PTL_BUS becoming PTL_BUSNEW below.
|
||
|
||
If you have a complicated template, set `verilog-auto-inst-template-numbers'
|
||
to see which regexps are matching. Don't leave that mode set after
|
||
debugging is completed though, it will result in lots of extra differences
|
||
and merge conflicts.
|
||
|
||
For example:
|
||
|
||
/* InstModule AUTO_TEMPLATE (
|
||
.ptl_bus (ptl_busnew[]),
|
||
);
|
||
*/
|
||
InstModule ms2m (/*AUTOINST*/);
|
||
|
||
Typing \\[verilog-auto] will make this into:
|
||
|
||
InstModule ms2m (/*AUTOINST*/
|
||
// Outputs
|
||
.NotInTemplate (NotInTemplate),
|
||
.ptl_bus (ptl_busnew[3:0]), // Templated
|
||
....
|
||
|
||
@ Templates:
|
||
|
||
It is common to instantiate a cell multiple times, so templates make it
|
||
trivial to substitute part of the cell name into the connection name.
|
||
|
||
/* InstName AUTO_TEMPLATE <optional \"REGEXP\"> (
|
||
.sig1 (sigx[@]),
|
||
.sig2 (sigy[@\"(% (+ 1 @) 4)\"]),
|
||
);
|
||
*/
|
||
|
||
If no regular expression is provided immediately after the AUTO_TEMPLATE
|
||
keyword, then the @ character in any connection names will be replaced
|
||
with the instantiation number; the first digits found in the cell's
|
||
instantiation name.
|
||
|
||
If a regular expression is provided, the @ character will be replaced
|
||
with the first \(\) grouping that matches against the cell name. Using a
|
||
regexp of \"\\([0-9]+\\)\" provides identical values for @ as when no
|
||
regexp is provided. If you use multiple layers of parenthesis,
|
||
\"test\\([^0-9]+\\)_\\([0-9]+\\)\" would replace @ with non-number
|
||
characters after test and before _, whereas
|
||
\"\\(test\\([a-z]+\\)_\\([0-9]+\\)\\)\" would replace @ with the entire
|
||
match.
|
||
|
||
For example:
|
||
|
||
/* InstModule AUTO_TEMPLATE (
|
||
.ptl_mapvalidx (ptl_mapvalid[@]),
|
||
.ptl_mapvalidp1x (ptl_mapvalid[@\"(% (+ 1 @) 4)\"]),
|
||
);
|
||
*/
|
||
InstModule ms2m (/*AUTOINST*/);
|
||
|
||
Typing \\[verilog-auto] will make this into:
|
||
|
||
InstModule ms2m (/*AUTOINST*/
|
||
// Outputs
|
||
.ptl_mapvalidx (ptl_mapvalid[2]),
|
||
.ptl_mapvalidp1x (ptl_mapvalid[3]));
|
||
|
||
Note the @ character was replaced with the 2 from \"ms2m\".
|
||
|
||
Alternatively, using a regular expression for @:
|
||
|
||
/* InstModule AUTO_TEMPLATE \"_\\([a-z]+\\)\" (
|
||
.ptl_mapvalidx (@_ptl_mapvalid),
|
||
.ptl_mapvalidp1x (ptl_mapvalid_@),
|
||
);
|
||
*/
|
||
InstModule ms2_FOO (/*AUTOINST*/);
|
||
InstModule ms2_BAR (/*AUTOINST*/);
|
||
|
||
Typing \\[verilog-auto] will make this into:
|
||
|
||
InstModule ms2_FOO (/*AUTOINST*/
|
||
// Outputs
|
||
.ptl_mapvalidx (FOO_ptl_mapvalid),
|
||
.ptl_mapvalidp1x (ptl_mapvalid_FOO));
|
||
InstModule ms2_BAR (/*AUTOINST*/
|
||
// Outputs
|
||
.ptl_mapvalidx (BAR_ptl_mapvalid),
|
||
.ptl_mapvalidp1x (ptl_mapvalid_BAR));
|
||
|
||
|
||
Regexp Templates:
|
||
|
||
A template entry of the form
|
||
|
||
.pci_req\\([0-9]+\\)_l (pci_req_jtag_[\\1]),
|
||
|
||
will apply an Emacs style regular expression search for any port beginning
|
||
in pci_req followed by numbers and ending in _l and connecting that to
|
||
the pci_req_jtag_[] net, with the bus subscript coming from what matches
|
||
inside the first set of \\( \\). Thus pci_req2_l becomes pci_req_jtag_[2].
|
||
|
||
Since \\([0-9]+\\) is so common and ugly to read, a @ in the port name
|
||
does the same thing. (Note a @ in the connection/replacement text is
|
||
completely different -- still use \\1 there!) Thus this is the same as
|
||
the above template:
|
||
|
||
.pci_req@_l (pci_req_jtag_[\\1]),
|
||
|
||
Here's another example to remove the _l, useful when naming conventions
|
||
specify _ alone to mean active low. Note the use of [] to keep the bus
|
||
subscript:
|
||

Lisp Templates:
|
||
|
||
First any regular expression template is expanded.
|
||
|
||
If the syntax @\"( ... )\" is found in a connection, the expression in
|
||
quotes will be evaluated as a Lisp expression, with @ replaced by the
|
||
instantiation number. The MAPVALIDP1X example above would put @+1 modulo
|
||
4 into the brackets. Quote all double-quotes inside the expression with
|
||
a leading backslash (\\\"). There are special variables defined that are
|
||
useful in these Lisp functions:
|
||
|
||
vl-name Name portion of the input/output port.
|
||
vl-bits Bus bits portion of the input/output port ('[2:0]').
|
||
vl-width Width of the input/output port ('3' for [2:0]).
|
||
May be a (...) expression if bits isn't a constant.
|
||
vl-dir Direction of the pin input/output/inout.
|
||
vl-cell-type Module name/type of the cell ('InstModule').
|
||
vl-cell-name Instance name of the cell ('instName').
|
||
|
||
Normal Lisp variables may be used in expressions. See
|
||
`verilog-read-defines' which can set vh-{definename} variables for use
|
||
here. Also, any comments of the form:
|
||
|
||
/*AUTO_LISP(setq foo 1)*/
|
||
|
||
will evaluate any Lisp expression inside the parenthesis between the
|
||
beginning of the buffer and the point of the AUTOINST. This allows
|
||
functions to be defined or variables to be changed between instantiations.
|
||
|
||
Note that when using lisp expressions errors may occur when @ is not a
|
||
number; you may need to use the standard Emacs Lisp functions
|
||
`number-to-string' and `string-to-number'.
|
||
|
||
After the evaluation is completed, @ substitution and [] substitution
|
||
occur."

statement. Signals that are generated within the same always block are NOT

||
placed into the sensitivity list (see `verilog-auto-sense-include-inputs').
|
||
Long lines are split based on the `fill-column', see \\[set-fill-column].
|
||
|
||
Limitations:
|
||
Verilog does not allow memories (multidimensional arrays) in sensitivity
|
||
lists. AUTOSENSE will thus exclude them, and add a /*memory or*/ comment.
|
||
|
||
Constant signals:
|
||
AUTOSENSE cannot always determine if a `define is a constant or a signal
|
||
(it could be in a include file for example). If a `define or other signal
|
||
is put into the AUTOSENSE list and is not desired, use the AUTO_CONSTANT
|
||
declaration anywhere in the module (parenthesis are required):
|
||
|
||
/* AUTO_CONSTANT ( `this_is_really_constant_dont_autosense_it ) */
|
||
|
||
Better yet, use a parameter, which will be understood to be constant
|
||
automatically.
|
||
|
||
OOps!
|
||
If AUTOSENSE makes a mistake, please report it. (First try putting
|
||
a begin/end after your always!) As a workaround, if a signal that
|
||
shouldn't be in the sensitivity list was, use the AUTO_CONSTANT above.
|
||
If a signal should be in the sensitivity list wasn't, placing it before
|
||
the /*AUTOSENSE*/ comment will prevent it from being deleted when the
|
||
autos are updated (or added if it occurs there already).
|
||
|
||
An example:
|
||
|
||
always @ (/*AS*/) begin
|
||
/* AUTO_CONSTANT (`constant) */
|
||
outin = ina | inb | `constant;
|

out = outin;

outin = ina | inb | `constant;
|
||
out = outin;
|
||
end
|
||
|
||
Note in Verilog 2001, you can often get the same result from the new @*

||

AUTORESET will not clear memories.

AUTORESET uses <= if there are any <= in the block, else it uses =.

By default, AUTORESET will include the width of the signal in the autos,

Replace the /*AUTOUNUSED*/ comment with a comma separated list of all unused

|

|
||
/*AUTOUNUSED*/ is used to make stub modules; modules that have the same
|
||
input/output list as another module, but no internals. Specifically, it
|
||
finds all inputs and inouts in the module, and if that input is not otherwise
|
||
used, adds it to a comma separated list.
|
||
|
||
The comma separated list is intended to be used to create a _unused_ok
|
||
signal. Using the exact name \"_unused_ok\" for name of the temporary
|
||
signal is recommended as it will insure maximum forward compatibility, it
|
||
also makes lint warnings easy to understand; ignore any unused warnings
|
||
with \"unused\" in the signal name.
|
||
|
||
To reduce simulation time, the _unused_ok signal should be forced to a
|
||
constant to prevent wiggling. The easiest thing to do is use a
|
||
reduction-and with 1'b0 as shown.
|
||
|
||
This way all unused signals are in one place, making it convenient to add
|
||
your tool's specific pragmas around the assignment to disable any unused
|
||
warnings.
|

|

You can add signals you do not want included in AUTOUNUSED with

`verilog-auto-unused-ignore-regexp'.

|

Create a register to contain the ASCII decode of a enumerated signal type.
|
||
This will allow trace viewers to show the ASCII name of states.
|
||
|
||
First, parameters are built into a enumeration using the synopsys enum
|
||
comment. The comment must be between the keyword and the symbol.
|
||
\(Annoying, but that's what Synopsys's dc_shell FSM reader requires.)
|
||
|
||
Next, registers which that enum applies to are also tagged with the same
|
||
enum. Synopsys also suggests labeling state vectors, but `verilog-mode'
|
||
doesn't care.
|
||
|
||
Finally, a AUTOASCIIENUM command is used.
|
||
|
||
The first parameter is the name of the signal to be decoded.
|
||
|
||
The second parameter is the name to store the ASCII code into. For the
|
||
signal foo, I suggest the name _foo__ascii, where the leading _ indicates
|
||
a signal that is just for simulation, and the magic characters _ascii
|
||
tell viewers like Dinotrace to display in ASCII format.
|
||
|
||
The final optional parameter is a string which will be removed from the
|
||
state names.
|
||
|
||
An example:
|
||
|
||
//== State enumeration
|
||
parameter [2:0] // synopsys enum state_info
|
||
SM_IDLE = 3'b000,
|
||
SM_SEND = 3'b001,
|
||
SM_WAIT1 = 3'b010;
|

//== State variables
|
||
reg [2:0] /* synopsys enum state_info */
|
||
state_r; /* synopsys state_vector state_r */

|

I want to report a bug. I've read the `Bugs' section of `Info' on
|
||
Emacs, so I know how to make a clear and unambiguous report. To get
|
||
to that Info section, I typed
|
||
|
||
M-x info RET m " invocation-name " RET m bugs RET
|
||
|
||
Before I go further, I want to say that Verilog mode has changed my life.
|
||
I save so much time, my files are colored nicely, my co workers respect
|
||
my coding ability... until now. I'd really appreciate anything you
|
||
could do to help me out with this minor deficiency in the product.

||

||
If you have bugs with the AUTO functions, please CC the AUTOAUTHOR Wilson
|

Snyder (wsnyder@wsnyder.org) and/or see http://www.veripool.org.

You may also want to look at the Verilog-Mode FAQ, see
|
||
http://www.veripool.org/verilog-mode-faq.html.
|
||
|

To reproduce the bug, start a fresh Emacs via " invocation-name "
|

-no-init-file -no-site-file'. In a new buffer, in Verilog mode, type
|
||
the code included below.
