I am now do a SAR ADC design and need to do mixed-signal simulation on my design.
The digital part of the circuit is descripted with VerilogHDL at RTL level. And then I make it as a symbol and integrated into a schemetic with analog part. The stimulus to digital part is descripted with verilogHDL and the stimulus to analog part is directly added on the schemetic. And then I run the simulation with Cadence mixed-signal simulator. No error or warning reported, but no waveform output.
Would you help me to give an explanation?
