sine pwm pspice models

Hi,
I m doing work on Single-phase Unipolar Inverter , I have made all the schematics in Orcad Capture and want to simulate it on Pspice but problem is that how can i generate the PWM signal in Pspice.
 

pwm in pspice

As in a real circuit, have a sawtooth respectively triangle pulse generator and a comparator. Can be done with ABM blocks or regular parts.
 
Hi,
I m doing simulation for the first time in Pspice, so can you please send me the details how to generate these PWM signals by ABM block, My inverter is Single-phase Unipolar and I have to generate 4 pulses which will go to the four optocouplers.
Triangular Frequency is from 5-10KHZ and 50HZ Sinosuial.
