Complex-constant multiplier in VerilogA

RFStuff

 Dear All,

I am doing a PSS+PNOISE simulation of a circuit in Spectre.

I need to multiply the output voltage of certain terminals with Complex Constant ( exp(j*pi/4)=0.707+0.707i).

This I don't want for post-processing ( which can be easily done using Ocean Script).

I want it on the fly of simulation.

Is there any ways of achieving this in VerilogA.

Kind Regards,

Parents

  •  If you run an ac analysis on a system containing verilogA blocks and use the calculator to implement a multiplier function, is there any way to extract the dc component on the 'multiplier' output? In my example the multiplier inputs have no dc component but the multiplier output will have a dc component. I have simply done a real(VF("/in1")*VF("/in2")) and although I have a result, it does not look correct to me and am wondering about how to fully specify the complex nature of the signals in the calculation.

    Regards, James
