Title: HSPICE: How to write many runs to ONE out file?
Post by cheshire_cat on Nov 10^th, 2006, 11:21am

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.

-Chris

i think u can simulate a file at first, then open the Avanwaves to get the plot, then simulate each file step by step, but get the plot from the same Avanwaves window, cilck desing--> open, then u can get all your curves in one plot

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.
