Differential terminations work in Hyperlynx but you have to do two things.
One, when you assign the driver you have to assign the pin also. Second, if
you are using LineSim you need to use the free form schematic not the cell
based schematic. Needless to say you need to use the most current version
of the tool.

Hi
I am trying to run an LVDS simulation on a Xilinx Spartan 6 FPGA device. The
problem I have is that I am trying to use the internal receive termination.
When I select the device with this termination and try to run a simulation
Hyperlynx complains that it failed to model IBIS differential R_series at
the receiver input. I guess that this is something to do with the
termination but I am not sure what I have to do to fix the problem.
Thanks
Jon
