Hi, I have made progress with simulating Bode plot of closed loop of muy SMPS. The docment I found from TI https://www.ti.com/lit/an/sluaa51/sluaa51.pdf?ts=1607072449713&ref_url=h... states using .STEP, .TRAN, .PROBE64 and .options commands to set up the measurement during transient sim. I can't find these commands, does anyone know how to place these on the schematic? Thanks.

Those commands are not added to the schematic per se. Prior to running a simulation, you prepare your .cir file (the one executed by PSpice) through the "Simulation Profile" GUI. It is here that you can add those commands that you've referenced. From the PSpice menu select "Edit Simulation Profile" to do this.
