Latest Patents

Funabiki's patent, titled "Method and apparatus to generate test sequences for communication protocols," presents an innovative approach to generating test sequences. This invention inputs data from finite state machines (FSM) that represent the specifications of communication protocols. By converting the test sequence generation problem into the satisfiability problem (SAT problem), Funabiki's method is able to generate effective test sequences. It works by modifying the FSM and defining the problem with a conjunctive normal form formula based on the altered FSM. This dynamic approach includes consideration of multiple input/output sequences and overlapping sequences, ultimately generating the minimum length test sequences needed to verify whether the states specified in the protocol's specifications are present in the FSM implementation.
