       verga - VERrilog simulator for tkGAte


       verga  [-eslqi]  [-d  dtype]  [-S script] [-P mods] [-t mod] [-B dir] [-D hash] [-W wmode]


       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:


       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 internally by tkgate.

       -l             Show the verga license.

       -q             Run in 'quiet' mode, suppressing extraneous messages.

       -i             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' 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

       -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 warnings".


       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.
