hi,,,
how can i make an voltage source with the following waveform

period = 1ms
0<t<0.25 ms : V=1
0.25<t<0.75: V=0
0.75<t<1 ms :V=1

thanks alot....
 

Bsically it's a square wave with PW = 0.5 ms and TD = -0.25 ms. If PSPICE doesn't accept a negative TD value, you have to combine two VPULSE sources.

Try VPULSE with:
V1=1
V2=0
TD=0
TR and TP according to your requirements (nsec)
PW=0.25m
PER=1m
