Thanks a lot guys for your replies, I had to work the whole day today so I didnt have any time to test your solutions. I will try it first thing tomorrow and let you know how it went. Once again,thank you!
I noticed that even when I leave both input floating the simulation stays exactly the same as before,it still shows that straight line at the same voltage level,even more confusing,maybe that will help you understand what is going on,because I am stuck for days at this.
Double clicking on symbol...
I know that it should have a power supply but there is no other input on this symbol, except INPUT and RESET. I have a component and it has a clk input and a supply voltage but here in spice,this symbol does not have anything else. I guess I am missing something :D
Hi,thanks for your reply. I did as you said for the reset input, but the simulation stays the same. I am not sure what is the problem as this circuit really isn't that complicated. Thanks for the advice anyway! :)
I am trying to make a DAC R-2R ladder with CD4040B counter. Output should be a staircase but it is just a straight line in my simulation. I am probably doing something wrong as I am not that experienced with Spice so I would appreciate any help. I tried it without counter(just attached four...
