Hi everyone,

 Does any HSPICE user know how to write multiple runs within a deck (say I have 20 .alter statements) to a SINGLE .tr# file? I do not want to have 20 .tr# files. I have just returned to HSPICE from another SPICE-based simulator, which by default would place all runs into one output file. I would like this so that I may fire up CosmosScope and plot a variable for all 20 cases through just one plot file instead of 20.

I have looked through all the HSPICE documentation and it all refers to creating a unique .tr file for each result (tr0-19). What if I were to run MC simulations. Would HSPICE create 500 (e.g.) different plot files?? I cannnot believe it would.

Any other tips from somebody who interfaces HSPICE with CosmosScope would be appreciated. I used to run Saber and Scope together, and they are very slick. Very easy to plot hundreds of iterations.

Sorry, there is no way cause HSPICE to write only one waveform file for all .ALTER blocks in your netlist.  A Monte Carlo analysis is not the same.  Only one waveform file is written when you do a Monte Carlo analysis.

This is a case where AvanWaves is a better choice of waveform viewers since it understands the concept of a design and will open all the waveform files at one time.
