I do not have Verilog A or any analog software. Is Spectres enough for simulations of ADC or would it give me a wrong simulation output. I would like to know this little bit in-detial (i.e. why?). thanks.
In cadence ,first you can create a verilogA cell,(the code you can learn from the 8bit DAC or ADC in the AHDLib),and then create a symbol. this symbol of ideal DAC can help you simulation your owr adc.
