Saving MC simulation data for multiple temperature in OCEAN

Flyyn Rider

Hi everybody,

I am using Cadence IC6.1.5.500.9. I want to calculate spread in a circuit for various temperatures. One way is to do it manually at one temperature and then move on to next one but it is becoming cubersome as temperature points are too much. So i want to automate the process thru OCEAN and store the process data for different temperatures in a large csv file.

So as a first step I wanted to store the spread data in csv format for a MC simulations. I tried couple of commands listed in this forum and elsewhere but there was always some error. Like in this post:

www.cadence.com/.../1306400.aspx

I tried using:

prt=outfile("summaryReport.txt")
TrOcnxlOutputSummary(?output prt ?exprSummary t ?detailed nil)

close(prt)

but I got syntax error. Similarly I tried using code listed here:

secure.engr.oregonstate.edu/.../WritingCadenceOCEANScripts

This worked for ADE L but not ADE XL. Plus it generated data in text format.

I am not an advanced user of OCEAN so I am generating OCEAN script thru ADE XL and want to add some code to it for saving MC data. Then for saving data at multiple temperatures. Any comments on why the code in first link is not working? And where should I place the code for saving data? after the run command?

 

Regards 

  • Could you not create a corner in ADE XL with the sweep of temperature defined in the corner - e.g. -40:10:80 or -40,-10,20,50,80 or whatever and then do the monte carlo - you'll then get the distribution for each sub-corner (so each temperature). You could then save this to an OCEAN script if you prefer.

    Regards,

    Andrew.
