Hi experts:
     when i simulate BCM5421s with ibis model in hyperlynx, a error
occured:"Differential pin 116 is paired with a Nc pin in component BCM5421s
of file E:\........"
     I open the model, the differential pins are like this in ibis file:
115   SGIN+      NC
116   SGIN-      NC

118   SGOUT+     NC
119   SGOUT-     NC

121   SCLK+      NC
122   SCLK-      NC

|************************************************************************
[Diff Pin]   inv_pin   vdiff        tdelay_typ
115             116     100mV        0
118             119     0V               0
121             122     0V               0



but the analog differential pins are OK, they are:
47    TRD[0]+    NC
48    TRD[0]-    NC
49    TRD[1]-    NC
50    TRD[1]+    NC

Could anyone provide some advices on fixing the problem? Thanks a lot.
