A sample HSPICE run

To run HSPICE

  • Log in Engineering Workstation
  • Type "ece383" at the prompt
  • Use command : hspice [input file name] > [output file name]
    • For example, "hspice myckt.sp > myckt.lis"
  • The output file ("myckt.lis") contains dc operating point information, and some other good stuff.
  • To view output waveforms (from dc, ac, or transient analyses, for example), type "awaves" at the prompt to launch the graphical viewer.

    Input File

    Below is a common source MOS amplifier with current source load for HSPICE circuit simulation.

.option post=2 nomod	* post: create gsi data file (used for viewing

			*	outputs on the screen)

			* nomod: removes model information from the output

			*	 file. This greatly shortens the length
