Worked on the OpenROAD repository to enhance RAM design layout abstraction, focusing on improving the accuracy of occupied-layer representation in the design flow. This involved refining rectangle definitions for metal layers using LEF and TCL scripting, which allowed for more precise abstraction in hardware layout design. Updated abstract LEF tests to align with these changes, ensuring that regression coverage was maintained and that improvements in layout representation were thoroughly validated. Leveraged expertise in EDA tools, TCL scripting, and hardware design to deliver a targeted feature that reduces downstream rework by increasing the fidelity of RAM layout abstractions within the project.
