Spectre Error using S-parameter with Multiple Reference Impedances

gwong

Error:Mismatch found between number of data and number of ports

I'm getting the above error when using s-parameter file that has multiple reference impedances: 

#       Hz      S       RI      R       1 1 50 50 1 1 50 50

If I change the line to (single reference impedance for all ports) the following, it works

#       Hz      S       RI      R       50

What's the proper way of defining multiple impedances so Spectre will run.

 Regards,

Gary
