Routing in SoC Encounter

oAwad

Hello all,

 I use command "placeInstance" to place some instances in the core and route them manually since I want a certain routing pattern, then I run the automatic routing to place and route the rest of the design keeping my previous instances and routed wires as fixed. But I find that SoC Encounter ignores all pins connected to the pre-routed wires (the ones I manually routed and assigned to be fixed before automatic routing), so how to let the tool not ignore those pins in routing ?

I want my manually placed instances and manually routed wires to remain fixed, the rest of the design be automatically routed accordingly without ignoring any pins. How to do that ?

Thanks

  • That is strange. Because encounter usually doesn't touch hand routed nets especially since you set them as fixed. Try skipping those nets when you route the rest of the design.

    Another dirty method would be to specify those nets as special nets
