assigning a complex value to a design variable in ADE assembler

atataba

Hi 

I'm trying to assign a complex value to a design variable so I can do sourcepull in cadence but it's been so frustrating with no solution. I have tried using 

Gamma_S = complex((mag * cos(theta)) (mag * sin(theta))) or Gamma_S = mag*cos(theta)+i*mag*sin(theta)

with no luck. Is it even possible to do it?

I appreciate any help.

    What are you hoping to do with this variable? If the simulator is spectre, then the netlist format does not support complex parameters (which is what the design variable would end up as), so this doesn't really make sense. You'd normally either use the native load pull capability in spectre (which I think you can use for source pull too) or use the portAdaptor component which has separate mag and phase parameters. For some info you might want to look at these articles:

    We used to have a good workshop on load/source pull but it got out of date and hasn't been replaced yet, sadly.

    Regards,

    Andrew
