How to correlate RC/PLE results with FE/CTE?

archive

Hello all,

I'm trying to use FE/CTE to perform STA pre-layout but I don't know how to correlate the STA results of RC (using PLE) with the results from CTE.

I found the following help messages in sourceLink but they seem to be conflicting:
sourcelink.cadence.com/.../11286284.html
sourcelink.cadence.com/.../11350058.html
sourcelink.cadence.com/.../11249762.html

Can anyone help me?

Regards,
Cristiano.

  • Hi Cristiano,

    I was told that the new version of RC will be able to write out a SDF. It will then be possible to correlate RC and Soc for the purpose of checking that both tool interpret the constraint in the same way. But I think this is only possible for setup as several features for hold STA is not present in RC.

  • Hello,

    Someone told me that RC is able to generate SPEF file. I think it is a better solution than generate a SDF or a set_load file.
    Another point:
    It seems that RC automatically considers high fanout nets as ideal during synthesis. Is it true? How to consider these same nets as ideal in FE-CTE for STA prelayout?

    Regards,
    Cristiano.
