Fizzim - an open-source FSM design environment.
==============================================
Paul Zimmer - Zimmer Design Services
Michael Zimmer - Zimmer Design Services and UCSB
Brian Zimmer - Zimmer Design Services and UCD
Readme for versions:
v8.04.05 of fizzim.jar
v2.0 of fizzim.pl
New features / bug fixes:
(GUI unchanged)
fizzim.pl:
   -  Added support for whitespace in .fzm file
   -  Changed both regdp and comb block output structures to use a default
      value ahead of the case statement, then only output values that don't
      match the default.  If no default is supplied, fizzim.pl issues a
      warning and uses 0.  This improves out-of-the-box synthesis results.
   -  Official support of -terse mode.  Added alias of -sunburst to -terse.
   -  Changed case (1) in regdp output to use 1'b1 and parallel_case full_case
      just like nextstate comb block.  This improves out-of-the-box synthesis
      results for onehot.
   -  Added onehot_pragma attribute to allow override of parallel_case
      full_case.

Running the gui:
Fizzim is written in Java and runs under the Java Runtime Environment.  This
is installed on most systems.  On PC, just double-clicking the .jar file will
usually be enough to start the app.  If that doesn't work, you can start it from
the command line like this:
java -jar fizzim.jar
Java version 1.5 ("Java 5") or greater is required to run fizzim.  If you only
have Java 1.4, there is a eval version of fizzim.jar for 1.4 on fizzim.com.
But this is intended for evals only.  Don't bother to submit bugs on it -
they won't be fixed.  Upgrade to 1.5 or greater.
Running the backend:
The backend is written in perl.  This is loaded on all unix systems.
You can download it for your PC from perl.org.
On unix systems, the "sh-bang" at the start of the file will tell the shell to
run perl, so you can just execute the script:
fizzim.pl < your_fsm.fzm
On PC's, your shell might not recognize sh-bang, so you may have to use this:
perl -S fizzim.pl < your_fsm.fzm
