Hi, Diemilio,

My answer is good for PSpice (ORCAD):

In TRAN setup you have to activate FOURIER and to specify the fundamental frequency of the signal you want to analyze as well as the corresponding node voltage. After completion of the analysis the result (THD in %) is written in the *.out-file.
