As I received the buttons, I was able to not only get electrical information but also dimensions. I updated the layout:
The 50 buttons easily fit in a 18×18cm square so 20×20cm is a safe dimension for this panel.
Remember that it's only the instruction, and more things are done in other panels :
- The disassembly panel shows the instruction being sent to the core (it's the reverse of the ASM panel)
- The control panel selects the source of the instruction, generates the clock, sends the clock pulses to the core (one-shot, several ones or continuously)
- The debug panel has several event counters that can stop the core...
- More panels display the inner state of the core
