Latest Patents

One of his latest patents is titled "Equivalence classes over parameter state space." This invention provides an approach where an equivalence class generator selects a configurable module that includes control points and configuration parameters. The configuration parameters define a parameter state space of the configurable module. The equivalence class generator utilizes the control points to generate equivalence classes, which include class representatives that indicate values for the configuration parameters. Subsequently, one of the class representatives is selected and verified from each of the equivalence classes. This verification process ensures the accuracy of the parameter state space of the configurable module.

Another significant patent by Xiushan Feng is "Integrated circuit design verification through forced clock glitches." This technique determines whether an integrated circuit design is susceptible to glitches by identifying storage elements in an original register-transfer level (RTL) file of the design. It also involves identifying clock signals for each of the storage elements and generating respective assertions for each identified clock signal. The technique identifies potential glitchy logic in respective clock paths and inserts glitches in each of the respective clock paths of the original RTL file to create a modified RTL file. Finally, an RTL simulation is executed using the modified RTL file and the respective assertions.
