Title: Innovations by Subramanian Venkateswaran

Introduction

Subramanian Venkateswaran is a notable inventor based in Sunnyvale, CA. He has made significant contributions to the field of ASIC design through his innovative patents. With a total of 2 patents, his work focuses on improving the accuracy of delay calculations in integrated circuits.

Latest Patents

Venkateswaran's latest patents include a "4 point derating scheme for propagation delay and setup/hold time computation." This invention discloses methods for calculating delays for cells in ASICs by considering various factors such as process (P), voltage (V), temperature (T), input ramptime (R), and output load or fanout (F). The delays are computed by fitting the delay at four corner points for derated PVT conditions into a non-linear equation. This approach results in a five-dimensional characterization, which is split into (P,V,T) characterization and (R,T) characterization to optimize time and resources. The invention provides accurate calculations of delays for cells in ASICs.

Another patent is the "4K derating scheme for propagation delay and setup/hold time computation," which follows a similar methodology. It also emphasizes the importance of the same parameters (P, V, T, R, and F) in achieving precise delay calculations for ASIC cells.
