convergence error on counting circuit

[potency]

Ignore all the extra stuff, alot of it was for troubleshooting so it looks messy.  It seems to give me the error when i hook the 7 segment display up to ground. If i just let it run without it connected, the leds light up approprately.  As soon as it's connected, i get convergence.  I tried all the time step stuff too.  No luck.

Here's what I found. Goto SIMULATE>DIGITAL SIMULATION SETTINGS and change itr from IDEAL to REAL. This will require you to place the following power sources on the schematic somewhere: VCC, VDD, DGND, VSS.  This should get it simulating without the error message popping up.

I do not know why the 7-seg displays don't work under the IDEAL Setting, but most of the time I have observed that they don't. Usually when I am going to use them I have to set the simulator up as described above.

I hope this helps

Works great now thank you so much!
