摘要: A dynamic hardware emulation model (10) to be used with a hardware simulator for testing a user device(26) under test. A programming interface (12) controls a memory pool (14) and a command processor/bus manager (16) such that a command cycle is initiated to read and write data through a computer bus (24), to and from the user device (26). The programming interface (12) and the user device (26) can act in a master or slave mode. When the user device (26) is in slave mode, a slave memory (18) contains expected data for comparison purposes, and an arbiter (20) determines which device will have access to the computer bus (24).
