Title: Innovations by Sreekala Anandavally

Introduction

Sreekala Anandavally is a prominent inventor based in Karnataka, India. She has made significant contributions to the field of technology, particularly in the area of error management and diagnostics in computing systems. With a total of three patents to her name, Sreekala's work has had a substantial impact on the industry.

Latest Patents

One of her latest patents is titled "Error injection for timing margin protection and frequency closure." This innovative method involves executing a pre-silicon operation on a simulated chip to verify that a plurality of latches from a timing simulation set error checkers when run against a manufacturing test suite. The process generates a cross-reference file containing latch entries in a table. It also includes executing a first post-silicon operation on a hardware chip based on the simulated chip to determine empirically that timing latches from logic built-in self tests ('LBIST') trigger the same error checkers set by the plurality of latches verified in the simulated chip. The method updates the cross-reference file based on the results of this determination. Additionally, it executes a second post-silicon operation on the hardware chip to improve chip frequency by working around functional checkers using the cross-reference file and updating it based on the results of the improvement.

Another notable patent is related to "Core diagnostics and repair." This invention comprises an apparatus that includes a first core susceptible to an error condition and a second core configured to perform diagnostics on the first core. The goal is to identify the cause of the error condition and determine an action to remedy it, thereby recovering the first core.
