what's the hspice command to find out the icmr(input common mode range), cmrr(common mode rejection ratio) and psrr(power supply rejection ratio)? or do i need to use functions? all the commands i know for analysis are: .ac .dc .tf .trans .fft .probe .plot .print .op

For those measurements you perform the simulation of the circuit using the transient (.tran) analysis, use the .probe and .plot commands to see the results, and then calculate the icmr, cmrr and psrr from the simulation results.
