Title: Shiu-Ping Chao: Innovator in Integrated Circuit Design

Introduction

Shiu-Ping Chao is a notable inventor based in Los Altos Hills, California. He has made significant contributions to the field of integrated circuit (IC) design, holding a total of 2 patents. His work focuses on enhancing the efficiency and effectiveness of IC layout processes.

Latest Patents

Chao's latest patents include an innovative IC layout system that features separate trial and detailed routing phases. This integrated circuit layout process is organized into two distinct phases. During the first phase, a preliminary placement plan is generated, fixing the position of every cell of an IC design described by a gate level netlist. A trial routing plan is also established, which outlines approximate routes for the nets that interconnect cell terminals. The placement and trial routing plans are iteratively analyzed and modified to ensure compliance with various design constraints, including signal path timing and power distribution. In the second phase, the trial routing plan is converted into a detailed routing plan that specifies the exact routes for all nets, ensuring that the layout meets all design requirements.

Another significant patent by Chao is related to design hierarchy-based placement in computer-aided electronic design automation software. This placement system biases the clustering of cells according to their hierarchical design while optimizing placement to control die size and total wire length. The system also incorporates slack distribution, row improvement, and randomization during partitioning, along with floor plans based on trial placement and placement guiding blocks.
