Evaluating Outputs For Running ADE Assembler/Explorer Simulations

BTW the only way I can do this now is to manually, output-by-output, corner-by-corner, to load the output expression into the calculator and evalute it.  This is not a workable solution as I have number of corners and outputs to go through.

One method is to use an ocean script to navigate through all your corners and compute the output(s) that are available prior to simulation completion. The script can write the outputs in a format you specify to a file for further post-processing or alternately plot them in ViVA. 

I've included a model ocean script to traverse an Assembler results database most recently in the Forum post at URL:
https://community.cadence.com/cadence_technology_forums/f/custom-ic-design/47844/ocean-script-for-printing-parametric-sweep-dcop/1373753#1373753

This contains a link (shown below) to a second Forum post with the sample code. The prior Forum link includes a couple of changes to the code to accommodate Assembler as the script was initially used in the former ADE-XL.

Hi Shawn,

Thanks for script!  I modified for my case but it worked Perfectly!

My basic steps.

1 ) I dumped an ocean script from ADE Assembler to get all my expressions

2) grabbed jus the Expression lines:  grep ocnxlOutputExpr oceanScript.ocn     

3) With a little search/replace magic in notepad++ I converted those expression lines to variables and added them to the loop in you script 

foo = average(IT(\"/vsupply\"))

4) Used fprintf to print the variable values to a file.

Regarding the code snippet in you linked posts to the oceanxl style:  How do you load the results when using oceanXL?  Do you have to wait for the sim to complete?

Great! I am very happy to read you were able to make some progress!

I do not have access to the latest documentation on the use of oceanXL, but in the past you could view the results of a simulation run using oceanXL using through the History tab of the Data View assistant pane. You should be able to right-click the history item for the OCEAN run and choose View Results. If the simulations are in progress, you need to close and reopen the results to view the updated data.

You should not have to wait for them to complete to view partial results if you close and the reopen the OCEAN history item.

I hope this helps llamaspydog,

Shawn

I meant to reply to this thread to mention that there is an existing enhancement change request (CCR 1511773) asking for this with a number of duplicates. You might want to contact customer support to request a duplicate in order to register your interest and increase the likelihood of this being implemented.
