I downloaded your display scheme but after opening with Simulide 0.4.14-SR4 it crashed immediatly.
I opened simulide again, tried to drag Bcd to 7 segm decoder driver CD4511 from the components list into the empty circuit and whop it crashes. Other (CD4xx)-components do not cause this. I checked folder share-data-icCD and the (LS)package and subcircuit are there.
Tried it with 0.4.13-SR5 and that gives no problem at all, I can open your dynamic display and run it.
Runs very nice except the display at the top. The transistors are flashing but the driving CD4511 is not moving so the top display stays off.
Topdisplay is on now, the CD4511 is working. When I downloaded it the wires where mixed up, I compared it with your picture and rearranged them. I'm talking about version 4.13 now. The other one, 4.14 crashing is not solved yet. Just wanted to let you know that maybe there is a problem with that 4511-package in 4.14.
