Worked on the OpenROAD repository to enhance code readability and maintainability by standardizing interval notation for the shrink_ variable in dbChip.h. Focused on code refactoring and documentation using C++, the update replaced the nonstandard ]0, 1] interval with the more widely recognized (0, 1] format. This change was carefully implemented to be low-risk and non-breaking, ensuring that both the header file and the associated dbChip.json configuration remained consistent. By clarifying interval constraints, the work reduced ambiguity for future contributors and improved the overall consistency of constraint handling across the codebase, supporting clearer future code reviews.
