Abstract
A trace memory in the emulator is formed into a plurality of memory banks. Data to be traced is in principle stored sequentially in each memory bank. A trace condition setting circuit (trace registers) and a trace condition agreement detecting circuit (comparators) are provided to generate a valid/invalid flag FB indicating whether or not the data meet the set condition. This flag FB is stored along with the trace data in each memory bank.
