PLE adjusting in Rtl compiler

archive

Hi guys,

Does anybody know how to adjust PLE setting in RTL compiler so it will be more in line with encounter results?

I heard somebody talk about it, but he is not available now.

Any help would be appreciated.

Thanks,

Manzur.

  • Cristiano,
    You will not find any explanation of how RC computes the net length as it is a proprietary algorithm. About all I can tell you is that PLE uses a combination of the information in the LEF and capTable along with the structure of the logic to model the nets more accurately than any wireload. You will find that the results after Place and Route will be better using PLE's. It is important to note that the PLE flow is meant to make the post P&R (read REAL) results better. Depending on how conservative your WLM's are, the QoR results post synthesis could be either better OR worse.

    Hope this helps.

    Regards,
