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 ,
     Since 3 years we are using Soce and i have not fased such problems ,
    Its duffecult to justify the right reason for such issues spacific to your design .
    check how are the WARNINGS and ERROR msg.  at the time of loading and running nano route.
    In practical I have even limited using some layers on all subversion of 4.1 . -NO PROBLEM .

    If possible can you please let me know on which technology and your encounter.log & cmd file ... not all only the Nano route attrebuts and reported log.

    advice  before sending more details
    1. before globaldetail  route just check  Global Route .
    and check each layer conjesion map .
    during Global route check :

    #Start data preparation...

    # #Using automatically generated gcell grid.

    #Total wire length on LAYER M4 = 5812 um.

    #Total wire length on LAYER M5 = 5344 um.


    2. use Routing Control ( area Route ) and try .
    [command ]
    globalRoute
    detailRoute
    globalDetailRoute

    ################## # Routing Control ##############
    #### [option]
    setNanoRouteMode -routeSelectedNetOnly false (bool)
    setNanoRouteMode -routeBottomRoutingLayer default (integer/dynamic)
     setNanoRouteMode -routeTopRoutingLayer default (integer/dynamic)
    setNanoRouteMode -routeWithEco false (bool)
    [command]
     globalDetailRoute
    detailRoute
