Abstract
A memory emulation test system is provided with a method of and system for fast functional testing of memories, such as boot ROMs, in microprocessor-based assemblies. The emulative test system includes a synchronization circuit which automatically re-arms itself and generates sync pulses on each and every UUT data access cycle to allow the UUT microprocessor to read every boot ROM memory location and collect data to be computed into a checksum or other signature to be compared with a predetermined signature representative of a correctly functioning and faultless boot ROM.
