logic gate simulation problem

[allen]

Hi, all:

I use orcad 9.23 edition to run a digital simulation of phase detector.

I write a *.stl file to stimulus. And select DSTM symbol, time scale is

Micro second.

No error shows when simulating, but no waveform shows.

I don't know where the problem is. I have tried for almost five days, no

solution found.


Any suggestion is appreciated.

Thank you all

allen

Post your schematic to alt.binaries.schematics.electronic

I love to cook with wine. Sometimes I even put it in the food.

It couldn't be as simple as not having Markers on the schematic to
automatically pull up waveforms after simulation, could it?

Don't know if you're really new to Orcad or not.

Does the plot Window automatically open at the end of simulation but has
nothing in it? If so, and it is this simple then just select (Add Trace or
hit "Insert" on the keyboard) a trace to plot.

But most likely it's not something this simple.

OP can't post to a.b.s.e but he sent me a schematic in a DOC file :-(

It's Ron Treadway's and my old phase detector, the "nine-gate-wonder".

I sent the OP a suggestion on how to excite it... it takes a long
stream of f and 1.01*F to really see how it works.
