From the project
KiCAD EDA automatic component placement tool
atoplace is an intelligent orchestration layer for PCB design that bridges the gap between schematic and physical layout. It automates the tedious 80% of design—placement optimization and DFM validation—while strictly adhering to "Manhattan" aesthetics and Signal Integrity (SI) best practices.
Designed to work seamlessly with atopile and KiCad.
PCB layout automation has historically been "black box" and "messy"—producing organic, unreadable layouts that professional engineers reject. atoplace takes a different approach:
