[Magic-dev] Re: Re. 0.13um parameter file

[Martin, Mark]

Under the lib directory of the irsim source, you should find 
a calibrate_spice3 and a calibrate_hspice directory.  

The README under the calibrate_spice3 directory gives a description,
of the prm file.  There you will also find a script, some c code and 
sample decks to run spice and generate irsim parameters based on
the simulation results.

The scripts under calibrate_hspice are similar, but make use of the 
MEASURE feature in hspice to extract the numbers instead of the 
findr.c program in the calibrate_spice3 directory.

Hope this helps
Mark
