Setting differential random data source

Hadi Hayati
How can I find "differential random data generator" in Cadence? Is there such block in cadence or I have to make it by vpwl source in AnalogLib? Any suggestion will be appreciated... Regards, Hadi

  • Hi Hadi,

    You could use the vsource component in analogLib with the source type set to prbs.  This will create a pseudo-random bit sequence.  Alternately there is rand_bit_stream component in ahdlLib.  This is implemented with Verilog-A code so you could customize this to meet your needs if it does not currently do what you want.
