The line that you're using to probe the common mode voltage won't work.
Take a look at the Simulation and Analysis HSpice documentation for using
algebraic expressions.

[SI-LIST] Re: how to plot common mode voltage in Hspice

Hi
We need to do PCI-e gen1 simulations. I extracted s-parameters from
allegro. I used that extracted S-parameter for Hspice simulations. I am
getting single ended plots and differential plots, but I am not getting
plot for common mode voltage.
I am using following command in spice files.
.tran 5p 30n start=2n
.probe tran v(txp_pad,txn_pad) v(rxp_pad,rxn_pad) //for differential
plot
.probe tran V ((rxp_pad+rxn_pad)/2) // for common
mode plot
Is there something wrong with spice commands?
Please help? I am new to Hspice.
Regards
Piyush
