These are called autoplace and autoroute.
They exist, but NONE of the PCB designers I have worked with, all of who have worked at multiple big name tech companies and still do, use these tools.
Do the work. Even something as simple at a guitar amplifier needs attention to detail, to route ground currents away from where they can cause noise. Even something as simple as a guitar amplifier needs attention to the current handling needs of individual traces. Even something as simple as a guitar amplifier needs attention to the detail of proper component placement to minimize inductance where necessary between bypass caps and their associated IC's. DO THE WORK!
- exabrial 10y ago:) Thank you for the encouragement. That's good information to know. I've got a hand wired prototype, and it seems to work ok, so my PCB is going to be similar. That's one nice about (tube) guitar amplifiers: max current is at the power supply pin, about 72ma, despite transferring 27w or so. So your voltages are pretty high , but your traces can be pretty thin. The big thing is leaving plenty of space to prevent arcs.
- nibnib 10y agoYou also need to allow for failure conditions. If a power tube fails as a short or low impedance, which will vaporise first: your thin tracks, or your fuse?
