Spectre S-parameter analysis

cADEUser

I am doing s-parameter analysis using spectre "SP" analysis.  Few question : 

1) I have placed 40 ports ( port from analogLib) and attached to the appropriate nodes in the circuit. I have numbered them as 1 to 40.  Do I need to tell the tool which ones is input and which ones are output ?

2) In the ADE analysis GUI I have given the port name in the following form. 

3) Is there any way to put all the S11/S12/S13......etc in the output so that I can view them in the result analysis as soon as the simulation is done ? 

4) How do I save the s-parameter result in a touchstone file format ?

    Thanks Andrew for the details. Both of your suggestions worked. I tested ISR11 and it worked.  Also this method gave me the form "errsetstring(hiGetCurrentForm()->sp_asiiOptionsFormButton->_callback)". Is that generic that I can use in other forms as well just in case, by changing <analysis>_asii<button>_callback ?

    Anyway ...looks like ISR11 has the fixes which is good.

    The expression should be generic - at least I think it's always errsetstring(hiGetCurrentForm()->analysis_asiiOptionsFormButton->_callback) . I wouldn't try to generalise it to other things on the form.

    If you're running ISR11, that must be an early access build since ISR11 isn't released yet (the fix seems to be in the released ISR10 too). Anyway, glad it's working now...

    Regards,

    Andrew.
