NAME
verga - VERrilog simulator for tkGAte
SYNOPSIS
verga [-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:

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 primar-
ily 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' 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 op-
tion should only be used by tkgate which writes the file
to simulate to a temporary file before invoking the sim-
ulator.
-W wmode Mode for warning message handling. Can be 1 for "ignore
warnings", 2 for "report warnings only if there were er-
rors", 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 be-
fore X11 was widely used. In this incarnation it was used by students
in the computer architecture course at CMU to develop a simple micro-
processor (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 im-
plementation 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.
