If you ever wanted to know more about the inner workings of the Z80 cpu I have found an awesome application the Z80 Explorer by Goran Devic found on this site It permits you to look at the Z80 down to the transistor level, run simulations to see what is being made active in the chip and a waveform window to see how the logic of selected nets interact. There is an experimental feature that will make logic diagrams of selected nets as well. There is also a very detailed online manual with it.

Also on his blog is a series detailing some of the logic inside the Z80. He shows how to interface an Arduino Mega to a Z80 to single step it to watch the various signals. He also has a very detailed blog on the A-Z80, a softcore Z80 on a FPGA synthesized from logic diagrams that make up the Z80. He even shows how to use the A-Z80 to run a ZX spectrum on a FPGA!

This site is a must see if you need information on the the Z80 down to the gate level!

Great find. I'll be having a proper look when I get some spare time.

Thanks for posting this.

Kind regards
