Operating Conditions during predict_qos and synthesize -to_placed process.

admin

Hi there,

How can I change the operating conditions to ensure that RC extraction agrees with my synthesis settings?

Is the RTL Compiler physical synthesis enough, or the best practice is to run trial place and route on the Encounter?

At least in Encounter I have more control over the RC extraction process.

Thanks

  • Hi Julian,

     not sure I follow your question but operating conditions used in RTL Compiler are honored during R/C extraction so both should line up when using RTL Compiler Physical. In addition operating conitions changes using something like

    set_attr temperature 43.2 [find / -operating_condition nominal] 

     will also be taken into account during R/C extraction

     hope this helps,

    gh-
