xtalk simulation failed

Upender

Hi ,

When doing cross talk analysis on a post -routed board,  cross talk summary window always gives the results as

 Victim XNet                       Victim Drvr                  HSOddXtalk  HSEvenXtalk  LSOddXtalk  LSEvenXtalk  Group  

xxxxx                               yyyyy                                        NA          NA           NA          NA           Group all_tw   

 for all nets.

Geometic window 16mils, trace width 4 mils.  spacing between aggressor and victim is 8 mils and they run 50mm in parallel..

The results always show NA .

does anyone know  to set any other parameters for xtalk. tool used Cadence 16.2 PCB SI XL.

 

Thanx,

Upen

  • Hi Chris,

    Wave form directory is not created when the simulation fails.

    I have a 20 layer symmetric stack –up, signals selected from some layer produce results,  few other layers does not give for the same case settings.

    Cross-section seems to be fine

    Field solver used is EMS2D

     

    Thanks,
