555 4017 led simulation using yenka program

Hi guys, just found this great program which can simulate electronic diagrams. It called Yenka and it was free for a 15 day trail.

The question I've got is how much voltage can the 4017 decade counter handle. I have simulated a bunch of 555 and 4017 led flasher circuits but the simulator all ways tells me the 4017 pin voltage has been exceeded and can only handle 1v.

Not familiar with that simulator, however, other simulators require a VDD=xxV parameter to model the supply voltage dependence of the 4000 series of CMOS logic.

Hola Alberto Leandro Tupone

You've bought the software ???
No.. .
Probably the temporary license period is over.

We could see us your design with the intention of seeking some mistakes ??
you could compress your file ***. YKA with WinZip or WinRAR and upload the compressed file.
Thanks a lot crutschow. Actually this is pretty weird, it doesn't take any voltage for above of 6v. I'll try the LTspice.
By the way, with this soft can also make a PCB? Thanks a lot! :)
