PAM3 voltage source

cADEUser

Is there any PAM3 voltage source in ADE/Spectre ? vsource from analogLib only supports NRZ and PAM4.

    To be specific, I am looking for PAM3 PRBS source.

    No, and strangely enough I've not found any requests for PAM-3 either. Probably worth contact customer support to request this, but in the meantime you might want to write a Verilog-A model to do it (say, for a random bit stream) - I don't think that would be very complicated to implement.

    Thanks Andrew.  I wrote a verilog-a and it works. I was hoping to use the vsource since I can add jitter ( Rj/Dj) from the vsource. I need to figure out reliable way of adding jitter in verilog-a module that I have created.
