Question About SetOptMode, Bob, are you there?

archive

hi bob, I got one question about setOptMode.

Last night, I type getOptMode command, I find the options:

-congOpt
-rebuffer
-incrTrialRoute

They are the hidden options for setOptMode, I want to know what their functions are, what command do they control, since optDesign is just a large tcl wrapper.

Thanks, Bob!

  • Many Thanks, Bob. I thinks I should clarify my current situation further.


    When I am closing the timing of my design, I found that in a timing path, there are a lot of cells titled '****_FE_RBC_****', they are buffers or inverters, after delve into this I found that these cells must be 'ReBuffer Cell'. As we know optCritPath will do this 'rebuffer' step. And I want to try if I switch this option off, what will happen to my timing.

    So I want to know the detail of this parameter.
