This is an example for hspice: .include 'opamp.sp' .global vdd vss x1 vp vn out opamp vdd vdd 0 10 vss vss 0 -10 vp vp 0 0 ac 1 0 vn vn 0 0 .op .option post .ac dec 10 1 1e+9 .noise v(out) vp 10 $ vp is the refered input .print noise inoise onoise $ ... .end The inoise is the input-refered noise and is printed into the hspice output file.
