Title: Sandeep S Deshpande: Innovator in Circuit Design Simulation

Introduction

Sandeep S Deshpande is a notable inventor based in Longmont, Colorado, known for his contributions to circuit design simulation. He holds a total of 3 patents that showcase his innovative approaches in the field of hardware description languages.

Latest Patents

One of his latest patents is titled "Operator aware finite state machine for circuit design simulation." This invention involves simulating a circuit design specified in a hardware description language (HDL). During the simulation, a thread is initiated at the edge of a simulation clock signal to evaluate the states of a finite state machine (FSM) that represents a series of events specified in the HDL. The thread transitions from one state to the next in response to the evaluation of the current state. When a fork state is encountered, the thread is divided into two threads during the simulation, representing a composite operator in the statement. The FSM has branches from the fork state for each operand of the composite operator. Upon reaching a join state in the FSM, the two threads are merged back into one.

Another significant patent is the "Framework for reusing cores in simulation." This invention focuses on simulating a hardware description language design that includes a core and a testbench. It involves performing a first compilation of the design using a processor, generating a compiled core unit for the core, a compiled testbench for the testbench, and synchronization data that describes signals crossing a compile checkpoint boundary. A subsequent compilation can then be performed by reusing the compiled core unit from the first compilation while generating a new compiled testbench using the synchronization data.
