Title: Pallab Kumar Dasgupta and Observability-Based Code Coverage.

Introduction

Pallab Kumar Dasgupta is an inventor associated with Andover, Massachusetts, and Synopsys, Inc. His patent work addresses observability-based code coverage, a technique for evaluating whether design statements in a circuit become observable during simulation.

Latest Patents

Dasgupta is named on 1 patent: “Method and Apparatus for Observability-Based Code Coverage.” The invention augments conventional simulation signals with tag values. Assignment statements inject tags onto their output signals, and each tag identifies the statement that produced it while carrying a history of tags from earlier control or data flow. When a tag propagated through the design under test reaches an observable output, designers can determine that the identified statements have met observability-based coverage.

Career Highlights

The patent reflects work at the intersection of hardware design, simulation, and verification. By tracking the origins and histories of signal values, the method offers designers a way to assess whether particular assignments can affect observable outputs.

Collaborations

Dasgupta’s listed coworkers include Debashis Roy Chowdhury and Surrendra A. Dudani. His patent is associated with Synopsys, Inc.

Conclusion

Pallab Kumar Dasgupta’s patent presents a tag-based approach to observability coverage that helps circuit designers trace assignment statements through simulation and determine whether their effects reach observable outputs.
