timing simulation problem!!!

hi all ! I've designed a simple circuit and made a functional simulation. It seemt working how I want. But in timing simulation it didnt worked truly. So what do you think the problem is? :con...

Hi,

For a good starting practice in problem solving, I suggest that you first identify the problem.

First convince the forum that the functional simulation does work

then convince the forum that it is indeed the timing to blame.

If you blame the timing simulation make sure you are reading the waveforms corrctly and that your clock speed is not exceeding your Fmax.

Good luck
