Title: Dhananjay Kumar Griyage: Innovator in Signal Integrity

Introduction

Dhananjay Kumar Griyage is a notable inventor based in Sunnyvale, CA (US). He has made significant contributions to the field of signal integrity, holding 2 patents that showcase his innovative approach to circuit design.

Latest Patents

One of his latest patents is titled "Signal integrity delay utilizing a window bump-based aggressor alignment scheme." This application discloses a computing system designed to determine a timing window for the reception of a signal propagated through a victim channel in a circuit design. It generates an aggressor window bump for each noise bump that can be induced on the victim channel by one or more aggressor channels. The system determines a delta delay corresponding to the timing window for the signal based on the aggressor window bump and utilizes this delta delay to assess whether the victim channel operates within a timing constraint associated with the circuit design.

Another significant patent is the "Lumped aggressor model for signal integrity timing analysis." This model simulates multiple aggressor nets acting on a victim net by lumping the aggressor nets together into a single input port. A single voltage excitation can be applied to simulate the model during static timing analysis. However, it maintains a record of each individual aggressor net and several associated attributes, allowing for separate contributions to the attack on the victim net.
