Won Sub Kim

Title: Biography of Won Sub Kim

Introduction: Won Sub Kim is an accomplished inventor based in Fremont, California. He holds a total of 12 patents, showcasing his innovative contributions to the field of technology.

Latest Patents: His latest invention is a method and apparatus for random stimulus generation. This invention enhances a Hardware Verification Language (HVL) by facilitating the generation of random test data. Random variables can be produced by adding a randomness attribute to a variable declaration within a class definition. A 'randomize' method call to a class instance generates random values for each random variable. Constraint blocks within the class definition control these random variables using constraint expressions. The dependencies of random variable value assignments, as determined by these constraints, can be expressed through directed acyclic graphs (DAGs). The constraint expressions are converted into ranges of permissible values, from which a value is randomly selected. The 'boundary' method call allows for the sequential selection of boundary values for each random variable, enabling the production of all combinations of boundary values through successive calls.

Career Highlights: Throughout his career, Won Sub Kim has worked with notable companies such as Synopsys, Inc. and Maspar Computer Corporation. His experience in these organizations has contributed significantly to his expertise in hardware verification and random stimulus generation.

Collaborations: Won Sub Kim has collaborated with esteemed colleagues, including Daniel Marcos Chapiro and John R. Nickolls
