Abstract
A system may include a synchronization device and an emulation chip including a processor and a memory. The processor may evaluate, during a first cycle, at least one of a set of one or more execution instructions in the memory or evaluation primitives configured to emulate a circuit, and evaluate, during a second cycle, at least one of the set of one or more execution instructions or a set of configured logic primitives. The synchronization device may interpose a gap period interposed between the first cycle and the second cycle such that during the gap period, the processor does not evaluate one or more instructions from the set of one or more execution instructions or re-evaluate primitives. The synchronization device may cause, during the first gap period, the emulation chip to perform refreshes on the memory of the emulation chip.
