S parameter model for PCB SI

Could anybody tell me how can i use s-parameter model for modelling my connectors. For back-plane connectors model i want to use s-parameter model instead of ibis model (.dml file). I am using Allegro PCB SI 15.5.

You will need a PCB SI 630 license to use S Parameters. The S Parameter models need to be converted to DML, take a look at the Model Integrity User Guide, miug.pdf in the doc\miug directory of the installation, page 24 "Converting and Normalizing Touchstone Files"

Hi
Depending on your needs you could also add the S-Parameters Option to a lower level tool than 630
Look at page 5-6 for the needed functionality at http://www.cadence.com/rl/Resources/datasheets/pcb_signal_ds.pdf

I have S-parameter model of "connectors". When I tried converting them to DML it gave error
"Error: The first statement line must be .subckt " . What's the reason for this. Kindly send me a link where S-parameter to DML conversion is explained nicely. I am using PCB SI 16.2/XL.

Thanks
Ajay

It would be great help if someone can reply to the post. I am not able to convert S16P file to DML using model integrity. I am using PCB SI GXL also.

Thanks and regards
Ajay
