Do you know any software for designing CPUs?

Minecraft has become really tedious and slow, specially when building big computers. Is there any program that lets me design CPUs?

I would recommend Logisim. I have used it to design (several) simple CPUs so its plenty capable enough, plus its free and fairly simple to use.
Want to design a PCB for your project? I strongly recommend KiCad. Its free, its multiplatform, and its easy to learn!
Also, I maintain KiCad libraries of Retro Computing and Arduino components you might find useful.

You might look into some of the tools used in From NAND To Tetris. They won't necessarily let you go to silicon, but are intended to teach you how to build CPUs from first principles and run stuff on them.
