Physical Design Python Code

✨ Features

• Rectilinear Polygon support

🚀 Recent Developments

• Deferred Merge Embedding (DME) Algorithm: Implemented the DME algorithm for clock tree synthesis, featuring a strategy pattern for delay calculation. This allows for flexible delay modeling, with both LinearDelayCalculator and ElmoreDelayCalculator provided as options. The algorithm is designed to build a zero-skew clock tree and includes functionalities for analyzing clock skew, total wirelength, and other tree statistics.
• Global Router Enhancements: The global router now offers multiple routing strategies to accommodate different design needs:
  • route_simple(): Connects terminals directly to the nearest node in the tree for quick and straightforward routing.
  • route_with_steiners(): Inserts Steiner points to optimize wire length, resulting in more efficient routing.
  • route_with_constraints(): A performance-driven approach that also uses Steiner points to reduce wire length.

Dependencies

• luk036/mywheel
