Title: Innovations by Michael Juergen Kessler
Introduction
Michael Juergen Kessler is a notable inventor based in Herrenberg, Germany. He has made significant contributions to the field of integrated circuit design, particularly in the area of test pattern coding. With a total of 4 patents to his name, Kessler's work has had a substantial impact on the efficiency of test data generation.
Latest Patents
Kessler's latest patents include a method and system for coding test patterns for scan design. This innovative approach allows for the efficient coding of test patterns for integrated circuits (ICs) using a built-in linear feedback shift register (LFSR) for pseudo-random pattern generation. The initialization procedure involves generating a novel LFSR logic model, which is integrated into the system for test data generation and test vector compression. During the test data generation procedure, test vectors are specified and compressed independently, resulting in a compact pattern code that can be processed further. Another significant patent focuses on random pattern weight control through the initialization of multiple pseudo-random bit-pattern generators (PRPGs), which are also LFSRs. This method allows for the control of the weight of the generated output-pattern by managing the number of zero-set LFSRs.
