DESCRIPTION
This man page describes about the SystemVerilog/Verilog parser for Universal Ctags.
SystemVerilog parser supports IEEE Std 1800-2017 keywords. Verilog parser supports IEEE
Std 1364-2005 keywords.

Supported Language Specific Fields
$ ctags --list-fields=Verilog
#LETTER NAME ENABLED LANGUAGE JSTYPE FIXED DESCRIPTION
- parameter no Verilog --b no parameter whose value can be overridden.
$ ctags --list-fields=SystemVerilog
#LETTER NAME ENABLED LANGUAGE JSTYPE FIXED DESCRIPTION
- parameter no SystemVerilog --b no parameter whose value can be overridden.
parameter field
If the field parameter is enabled, a field parameter: is added on a parameter whose value
can be overridden on an instantiated module, interface, or program. This is useful for a
editor plugin or extension to enable auto-instantiation of modules with parameters which
can be overridden.
$ ctags ... --fields-Verilog=+{parameter} ...
$ ctags ... --fields-SystemVerilog=+{parameter} ...
On the following source code fields parameter: are added on parameters P*, not on ones L*.
Note that L4 and L6 is declared by parameter statement, but fields parameter: are not
added, because they cannot be overridden.
"input.sv"
// compilation unit scope
parameter L1 = "synonym for the localparam";
module with_parameter_port_list #(
P1,
localparam L2 = P1+1,
parameter P2)
( /*port list...*/ );
parameter L3 = "synonym for the localparam";
localparam L4 = "localparam";
// ...
endmodule
module with_empty_parameter_port_list #()
( /*port list...*/ );
parameter L5 = "synonym for the localparam";
localparam L6 = "localparam";
// ...
endmodule
module no_parameter_port_list
( /*port list...*/ );
parameter P3 = "parameter";
localparam L7 = "localparam";
// ...
endmodule
$ ctags -uo - --fields-SystemVerilog=+{parameter} input.sv

TIPS
If you want to map files *.v to SystemVerilog, add --langmap=SystemVerilog:.v option.
