Multiple of waveform (voltage vs current)

my project is: The effect snubber on SiC IGBT. my circuit is buck converter with resistive load. i need to multiple voltage and current together. i think the waveform is wrong. the switching voltage is 30v and the switching current is around 2.5A. so the Plosses is around 75watts.. I used the normal Product block from the smiling library.

i have tried PS Product, but doesn't work at all. i have attached the waveform to it..

 can anyone help me in this in order to get the correct waveform???
