verga - VERrilog simulator for tkGAte
[-eslqi] [-d dtype] [-S script] [-P mods] [-t mod] [-B dir] [-D
hash] [-W wmode] [files...]
is a verilog simulator designed to be used with tkgate, but it can
also be used as a stand-alone simulator.
Verga documentation can be found at:
The options are as follows:
- Dump the list of error codes and associated messages that can be produced
by verga. This option is primarily for developer purposes.
- Scan a Verilog file and output information about its modules and nets.
This option is primarily used internally by tkgate.
- Show the verga license.
- Run in 'quiet' mode, suppressing extraneous messages.
- Run in 'interactive' mode. This mode is intended primarily for use when
verga is being invoked by tkgate.
- -d dtype
- Type of delays to use. Can be 'min', 'max' or 'typical'.
- -S script
- Load simulation scripts for each '-S' switch.
- -P mod
- Print the named module from the parsed structure for each '-P'
- -t mod
- Override the default and designate 'mod' as the top-level module.
- -B dir
- Directory to use as base directory when loading files
- -D hash
- Delete the input files after loading if 'hash' exactly matches a hash code
computed on the file name. This option should only be used by tkgate which
writes the file to simulate to a temporary file before invoking the
- -W wmode
- Mode for warning message handling. Can be 1 for "ignore
warnings", 2 for "report warnings only if there were
errors", 3 for "always report warnings" or 4 for
"always report warnings and stop simulator even if only
TkGate begin life as an undergraduate project at Carnegie Mellon University
(CMU) in 1987. At that time it was called simply 'gate' and ran under the 'wm'
window manager, a windowing system developed at CMU before X11 was widely
used. In this incarnation it was used by students in the computer architecture
course at CMU to develop a simple microprocessor (dubbed "The Bat
Computer"). After laying dormant for several years, it was resurrected in
1991 and ported to run under X11 with the Xlib API. In this incarnation it was
used several times by students in the introductory digital logic course, but
after the author graduated and left CMU, it went into hibernation again. This
Tcl/Tk incarnation was begun in 1998. While there is certainly some cruftyness
in the implementation in places due to the multiple reincarnations, many new
features have been added since the older wm and X11 versions, and the
interface has been made much easier to use.
