Hi

I tried implementing a schmitt trigger oscillator using orcad 9.
But it does not show the any waveform.just a dc of supply voltage at output
Why is that???
This is my circuit diagram

Hello, all right
I did the same circuit using Orcad 16.6 and got the waveform simulation in Orcad

Your circuit produced an output high of +6V when it had a +5V supply??

I suspect that the original OrCAD used did not know anything about the 74AC14 IC.
 

Remove the short circuit from the inverter output to GND, and your circuit should (may) work.
