SCRIPT  FILE  TO  COMPILE  FILES  FOR  VSIM

A script file can be written to compile source code for simulation. 
Below is the format of a script file that compiles four VHDL source code files.         

#!/bin/tcsh
vcom file1.vhd
echo "Press Enter to continue."
read answer
vcom file2.vhd
echo "Press Enter to continue."
read answer
vcom file3.vhd
echo "Press Enter to continue."
read answer
vcom file4.vhd

     To run your script file,

1. The file is placed in the directory in which the simulator is run, 



2. The
   chmod u+x filename
   command is typed at the unix prompt.



3. The
   prep mentor
   command is typed at the unix prompt.



4. The
   vlib work
   command is typed at the unix prompt.
