Segmentation fault in SoC Encounter 4.1 with Nanoroute

archive

Hi,
I want to route my design in SoC Encounter and I use the follow script for Nanoroute:

setNanoRouteMode -quiet routeFixPrewire true
setNanoRouteMode -quiet route_selected_net_only false
setNanoRouteMode -quiet routeWithTimingDriven false
setNanoRouteMode -quiet routeTdrEffort 1
setNanoRouteMode -quiet drouteFixAntenna true
setNanoRouteMode -quiet routeWithSiDriven true
setNanoRouteMode -quiet routeSiLengthLimit 200
setNanoRouteMode -quiet routeSiEffort normal

globalDetailRoute

This work without problem.
But as I want to avoid routing on the first layer, I also add the follow option:

setNanoRouteMode -quiet routeBottomRoutingLayer 2

But with this option the program report an segmentation fault.

What's I'm doing wrong?

Christian

  • Hi Christian,

    As Mohanch mentioned, it is impossible to route layer 1-7 if you have pin on metal1 (note: layer1 is metal1 and layer 7 is metal7).

    Most std cell pins are on metal1.
