I think I found your problems.
1. U4B doesn't seem to be connected. The grounds on the o-scope are not connected.
2. This is the real solution. Goto the Simulate Menu. Under Digital Simulation Settings. In the dialog box check the circle for Real.
3 Make sure you place VCC and a DGND connection somewhere on the schematic. I usually like to place VCC, VDD, VSS and DGND just to make sure I cover all the bases when it comes to digital components. These don't have to be connected to anything, but just have to be there when you use the Real Setting for Digial Simulation Setting.
I hope this gets you the result you were looking for. Have a Nice Day

Hi... having problems again.... when i simulate the circuit everithing is well but i pasted it into another project as a subcircuit and it doesn't work...
Please help
Thanks

Hi, i already modify the simulation settings... but it is still not working... It seems to be the inverter in the mxrthot_box, look at this and tell me what do you think... I modified the values of the vss source of that subcircuit but it affected all the others subcircuits so i modified the vss source in the 4009 (Switch subcircuit) and i called vss2 and it worked fine. Look at the 4009 in the mxrhot_box which is the one i think is not working.
Thanks
