How to Determine Via Locations？ #9

Open mayidu opened 2 years ago

mayidu commented 2 years ago

Hello, I am doing research on PCB wiring recently, can you share your algorithm or ideas on how to determine the location of vias on a multi-layer PCB? Thank you

Vias are simply any Z transition on a 3-D maze solve.

For through vias. Which is what I use in this solver.

I extend the collision case for any transition in Z to include the entire Z range in the 3-D hash map.
