Typical Overflow ?

archive
archive over 18 years ago

Hi,

I just wonder how much is the typical horizontal and vertical overflow so that the design be routable. I think this should depend on the number of metal layers in the design, I am using 6 metal layers in my design.

Thanks,

Houman

    Are you setting -updateRemainTrks for trial route? This option helps to better correlate trial route and nanoroute results.

    setTrialRouteMode -updateRemainTrks

    Determines whether to update congestion data after the layer assignment phase of Trial Route mode. Updating the congestion data displays congestion that is closer to the actual Trial Route result.

    From past experience if the trialroute results with -remainUpdateTrks are > than 4% over congested then nanoroute will not be able to route cleanly.


    Regards,
