Is there a way to add a normal buffer on a clock path

anil chatrathi

Hi All,

I have scan timing path where clock path is connected to SI pin as data and I have a huge hold violation on it.

Is there a way I can add a normal delay cell on the endpoint. 

ecoAddrepeater giving out an error saying that the wires of the net are fixed. I used db commands to set the the wires of the net as routed and tried the ecoAddrepeater commands. still it gives the same error message.

Help me if any one face the same type of issue.

Regards,

Anil

  • Hi,

    Try this

    addInst -cell <buffCell> -inst <instBufName> -loc <llx> <lly>

    addNet <newNetClock>

    attachTerm <instBufName> <input> <oldNetClock>

    attachTerm <instBufName> <output> <newNetClock>

    attachTerm <sinkInstName> SI <newNetClock>

    Finally make an ecoRoute


    Regards.
