Physical Design Entry Points

This directory contains physical-design integration entry points. The local Makefile is reserved for implementation flows that require the selected PDK, technology collateral, and often site-specific tools.

Generated layout, report, and database outputs must remain outside tracked source paths. Treat PDK-dependent physical-design results as toolchain-specific evidence and record the selected profile, PDK, and validation command when handing off a change. See Engineering Workflow.
