VERGA(1)VERGA(1)NAMEverga - VERrilog simulator for tkGAte
SYNOPSISverga [-eslqi] [-d dtype] [-S script] [-P mods] [-t mod] [-B dir] [-D
hash] [-W wmode] [files...]
DESCRIPTION
Verga 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:
http://www.tkgate.org
OPTIONS
The options are as follows:
-e Dump the list of error codes and associated messages
that can be produced by verga. This option is primarily
for developer purposes.
-s Scan a Verilog file and output information about its
modules and nets. This option is primarily used inter‐
nally by tkgate.
-l Show the verga license.
-q Run in 'quiet' mode, suppressing extraneous messages.
-i Run in 'interactive' mode. This mode is intended pri‐
marily for use when verga is being invoked by tkgate.
-d dtype Type of delays to use. Can be 'min', 'max' or 'typi‐
cal'.
-S script Load simulation scripts for each '-S' switch.
-P mod Print the named module from the parsed structure for
each '-P' specified.
-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
simulator.
-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 warn‐
ings".
HISTORY & CREDITS
TkGate begin life as an undergraduate project at Carnegie Mellon Uni‐
versity (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 stu‐
dents 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 crufty‐
ness in the implementation in places due to the multiple reincarna‐
tions, many new features have been added since the older wm and X11
versions, and the interface has been made much easier to use.
