Title: Chwen-Cher Chang: Innovator in Dynamic Logic Evaluation Systems

Introduction

Chwen-Cher Chang is a notable inventor based in Fremont, CA, who has made significant contributions to the field of electronic design automation and dynamic logic evaluation systems. With a total of 2 patents, his work focuses on enhancing the efficiency and performance of verification systems.

Latest Patents

One of his latest patents is a "Dynamic Evaluation Logic System and Method." This innovative system dynamically calculates the minimum evaluation time for each input in a verification system. By doing so, it alleviates the performance burden that a fixed evaluation time would impose. The system ensures that 99% of inputs are processed without delay, while only the 1% that require the worst-case evaluation time are affected. The dynamic logic evaluation system includes a global control unit connected to a propagation detector in each FPGA chip, which alerts the control unit of any input data currently propagating. This allows the system to adjust evaluation times based on the needs of the input data.

Another significant patent is for an "Electronic Design Automation Tool for the Design of a Semiconductor." This tool employs a single slack graph structure to facilitate communication between a placer and a timing constraint generator. It includes various components such as a slack graph generator, timing calculator, and timing analyzer, which work together to optimize the design process.
