Recipe for using Synopsys Simulation Tools


1) Setup Synopsys environment variables and paths

   a) Insert the following line to your .tcshrc (or .cshrc) file
         setenv SYNOPSYS /home/codes2/synopsys-sunos
            NOTE: bash users do the following in your .bashrc file:
               export SYNOPSYS = /home/codes2/synopsys-sunos

   b) Add the following three paths to your path command in the .tcshrc file
         (must appear after the above setting of the SYNOPSYS variable)

         $SYNOPSYS/sparc/syn/bin
         $SYNOPSYS/sparc/sim/bin
         /home/codes3/synopsys-doc

        eg. if your path command is 
           set path=(. /usr/bin /bin)
        then change it to
           set path=(. $SYNOPSYS/sparc/syn/bin $SYNOPSYS/sparc/sim/bin /home/codes3/synopsys-doc /usr/bin /bin)

   c) You should logout and then login again to make the above take effect
      (or source your .tcshrc file, if you know what that means).

2) Simulation

   a) First, login to either synthesis, which has 10 Synopsys licenses.
         %   ssh synthesis   
         %   setenv DISPLAY your_machine_name:0        // set your display
                NOTE: bash users do the following:
                   export DISPLAY = your_machine_name:0
         % source $SYNOPSYS/admin/install/sim/bin/environ.csh
                NOTE: bash users do the following: (.sh instead of.csh)
                   source $SYNOPSYS/admin/install/sim/bin/environ.sh

             

       
      

   b) Analyze your VHDL file
         % vhdlan yourfile.vhd    

   c) Bring up the debugger window with the entity you want to simulate
         % vhdldbx yourentity
                               // top half of window contains the source
                               // bottom half is the command window

   d) In the source code window, double click on a signal that you want to 
      trace, and then click on the Trace button.  This will bring up the 
      waveform window showing the trace of the selected signal. Repeat
      for additional signals. 

   e) In the command window, specify the time to run in the box next 
      to the RUN button (e.g., 100).  Click the RUN button. Repeat.
