- Introduced a new ECC directory containing scripts and Makefile for the padless ICS55 core hardening flow. - Updated the main Makefile to include the new ECC Makefile and added relevant help commands. - Added dependencies for the ECC CLI in the dependencies.lock.json file. - Created README documentation for the ECC flow detailing usage and requirements. - Implemented various scripts for configuration generation, validation, output checking, and packaging of ECC results. - Added unit tests to validate the ECC configuration and flow behavior.

Physical Design
This directory owns physical-design integration, managed technology inputs, smoke implementation-flow sources, and the self-developed commercial-flow drivers.
pdk/contains the locked PDK setup helpers and managed PDK checkouts.smoke/syn/contains Yosys synthesis and source-export integration.smoke/sta/contains OpenSTA constraints and timing integration.librelane/contains the open-source IHP130 core-hardening and full-chip pad-ring flows.ecc/contains the open-source ICS55 padless-core hardening flow backed by the locked ECOS Chip Compiler release.commercial/contains licensed-tool orchestration and flow logic. PDKs, foundry decks, commercial libraries, site configuration, and results remain outside Git.sdf/, when supplied by an implementation flow, contains post-layout netlist and SDF collateral consumed by post-layout simulation.
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.
