Title: Srivatsan Raghavan: Innovations in Electronic Design and Emulation.

Introduction

Srivatsan Raghavan is an inventor based in Karnataka, India, whose work focuses on electronic circuit design and emulation technologies. He is associated with Synopsys, Inc., and has 2 patents.

Latest Patents

Raghavan’s listed patents address challenges in verifying and efficiently emulating complex electronic designs.

“Detecting Instability in Combinational Loops in Electronic Circuit Designs” describes a method for identifying unstable combinational loops during circuit emulation. The method detects strongly connected components in a circuit design and inserts break registers to interrupt those loops. During an emulation run, it checks for value mismatches across the registers’ input and output pins and reports an instability event when mismatches indicate that a loop is unstable.

“Memory Profiler for Emulation” presents a method for estimating the sparse memory size needed during emulation. A profiler tracks which pages of user memory are used by a test sequence, identifies their indexes, and counts the unique pages. The system then uses that count and the memory page size to determine the sparse memory size.

Career Highlights

Raghavan’s patent work reflects an emphasis on practical tools for hardware verification. His inventions address two distinct needs: detecting instability in circuit behavior and measuring memory usage during emulation.

Collaborations

Raghavan is associated with Synopsys, Inc. His listed coworker is Mikhail Bershteyn.

Conclusion

Srivatsan Raghavan’s two listed patents contribute methods for improving circuit-emulation stability analysis and memory profiling.
