Title: Innovations of Ssu-Min Chang
Introduction
Ssu-Min Chang is a notable inventor based in Cupertino, CA. He has made significant contributions to the field of clock tree synthesis, holding a total of 3 patents. His work focuses on enhancing the efficiency and effectiveness of clock tree synthesis techniques.
Latest Patents
Ssu-Min Chang's latest patents include a "Multi-mode scheduler for clock tree synthesis." This invention describes techniques and systems for performing clock tree synthesis (CTS) across multiple modes. Some embodiments traverse one or more clock trees from the root to a set of sinks. During this traversal, each clock gate is marked with a traversal level, and each sink is associated with one or more clocks and modes. A task queue is created based on the collected information, populated with tasks that address skew balancing requirements across different modes. This task queue is then provided to a CTS engine to achieve high-quality skew-balanced clock trees across all modes.
Another significant patent is the "Automatic clock tree synthesis exceptions generation." This system automatically generates CTS exceptions by identifying sequential circuit elements that can be ignored during clock skew minimization. The process identifies elements whose clock skew cannot be balanced due to structural reasons, those without timing relationships, and those with sufficient slack to avoid timing violations. Clock tree exceptions are then generated based on these identified elements.
