Hspice in Linux

 $ csh

$ source /CMC/scripts/synopsys.hspice.2020.03.csh

Run HSPICE by typing

$ hspice rccircuit.sp > rccircuit.lis

This command will send the output from HSPICE to a file called rccircuit.lis. If you exclude the
second half of the command, the output will be shown in the shell itself. This can be inconvenient for
referencing and debugging, so it is common to send the output to a file.
