Differential signal simulation with bus switch ...

Using Hyperlynx V8.0, I am having getting a fatal error window stating:

 

"Line:231,  File:C:\views\mholley_HL8.0_2\hyp_src\bswDiffPair.cpp  File date:Apr 7 2009"

 

using a DDR3 DQS/DQS~ drivers going through a TI bus switch, TS3DDR3812_RUA, and terminates at a Hynex DDR3 DQS receiver.   What could cause this?  How can I fix this?

 

Note that,  I have added a DIFF_PIN section to the TI switch IBIS model:

 

|*******************************************************************************

|                                   DIFF PIN

|*******************************************************************************

|               if diff_pin is needed, you must edit this section

[Diff_pin]   inv_pin      vdiff        tdelay_typ   tdelay_min   tdelay_max

|

4            5            0.400V       0ns          NA           NA

6            7            0.400V       0ns          NA           NA

24           23           0.400V       0ns          NA           NA

22           21           0.400V       0ns          NA           NA

18           17           0.400V       0ns          NA           NA

16           15           0.400V       0ns          NA           NA

where those pins are connected to respective DQS/DQS~ lines.
