Abstract

See full text

A hybrid emulation system includes a hardware emulation system, a simulation system, and a co-simulation interface. The hardware emulation system emulates a first portion of a design under test (DUT) during a hybrid emulation. The emulation runs in a first time domain local to the hardware emulation system. The simulation system simulates a second portion of the DUT during the hybrid emulation. The simulation runs in a second time domain local to the simulation system. The first time domain and the second time domain are unsynchronized. The co-simulation interface is coupled to the simulation system and the hardware emulation system. The co-simulation interface communicates transactions and events between the hardware emulation system and the simulation system. For each transaction, the co-simulation interface captures a transaction time in the first time domain, and for each event, the co-simulation interface captures an event time in the first time domain.
