Is there a way to advance one tick without checking solution?

[Lord Emsworth]

It's unsatisfying that I can't mess freely with what I've made if it involves a delay.

When you get to higher levels you unlock a fast forward and if right click you change your speed. I ran a program at 1Mhz

you can copy your solution (Ctrl+A,Ctrl+C), go into sandbox, and then into component factory, paste your circuit with Ctrl+V, add back inputs/outputs, and play around
