Latest Patents

Chakraborty’s listed patents include two inventions related to electronic design verification.

“Power Aware Real Number Modeling in Dynamic Verification of Mixed-Signal Integrated Circuit Design” describes a method for synchronizing different representations of a power supply in a mixed-signal design. The method identifies mismatches between a power supply network description and a register-transfer-level hardware description, generates a value converter, and uses it during runtime to translate voltage values between the descriptions. This approach helps maintain consistency when verifying designs that combine analog and digital circuit portions.

“Assertion Extraction from Design and Its Signal Traces” presents a method for generating verification assertions from groups of signals in an electronic design. It samples signal values over a fixed-depth temporal window, organizes the resulting combinations into truth tables, and extracts functional relationships that can be used to create assertions. The method then filters and checks the generated properties, producing syntactically correct assert, assume, and cover statements for further simulation, emulation, or formal verification.

Career Highlights

Chakraborty’s patent portfolio reflects work on improving verification workflows for complex semiconductor designs. His inventions address both power-aware modeling across mixed-signal descriptions and the systematic generation of properties from design behavior. The listed record attributes 2 patents to him.
