US 11,080,446 B2 · Method to regulate clock frequencies of hybrid electronic systems

Abstract

A hybrid electronic system including an emulator side including a processor and a first clock, a simulated side including one or more models to simulate one or more prototypes and a second clock, a first interface to the emulator side, and a second interface to the simulated side is disclosed. The processor is configured to determine using the first interface a first amount of time corresponding to an amount of time advanced on the emulator side by the first clock. The processor is configured to determine using the second interface a second amount of time corresponding to an amount of time advanced on the simulated side by the second clock, and set a value of a clock frequency of the second clock based on an initial value of the clock frequency of the second clock and a ratio of the first amount of time to the second amount of time.
