Simulating a DAC in Cadence

I am trying to simulate a 8-bit DAC in Cadence I want to input all digitial input combinations from 00000000 to 11111111 (0 to 256) incrementing by 1 each time and also I can also hold it on a specific output to test the circuit. The problem is that is it not very feasible to set these inputs using 8 vpulse function

how can i solve this problem

thanks

You could use an 8-bit ideal ADC from ahdlLib and then ramp the input (adc_8bit_ideal would do the job).
