encounter : place/preplace buffers next to IO pads

Hello,

There are about 600 buffers which should be placed as close as possible to the io pads they are connected to. I set “set_max_capacitance 0” on the relevant nets before placement

> setPlaceMode -timingDriven false -reorderScan false -congEffort high doCongOpt true -modulePlan false -placeIoPins false -wireLenOptEffort high

>placeDesign –noPrePlaceOpt

It has not worked.

What is the recommended flow / solution for such cases?

Thank you.

Boris
