Hi,
I want to simulate a delta sigma modulator in Cadence spectre. I have a ctrl block in verilog-A and the main circuits in transistor level. I have also a digital filter of two cascased integrators which is defined in verilog module. Now I want to simulate this in spectre. but the problem is this digital filter works in logic levels (0,1) where the other parts in real analog voltage level. so is there any procedure in which i can change the digital level to analog levels?
thanks
