Latest Patents

One of his latest patents is titled "Metastability effects simulation for a circuit description." This innovative circuit design incorporates at least two clock domains and utilizes a novel system and method for injecting the effects of metastability. The system features detectors that identify when a clock in a transmit clock domain aligns with a clock in a receive clock domain, as well as when the input of a register receiving a clock-domain-crossing signal is changing. Additionally, the system includes coverage monitors that measure statistics related to metastability injection during simulation. By accurately modeling the effects of metastability, errors in circuit design can be detected while simulating a pre-existing simulation test. This simulation method is repeatable and does not require modifications to pre-existing RTL design files or simulation test files.
