Method and apparatus for correlating trace data from asynchronous emulation machines

Abstract

A method and apparatus are provided for correlating trace data from asynchronous machines, such as asynchronous emulation machines. A data capture signal is received from each of the plurality of asynchronous machines. The data capture signal from each of the plurality of asynchronous machines is sampled. Then the sampled data capture signal from each of the plurality of asynchronous machines and a cycle count are stored. A trace synchronization system is coupled to each of the plurality of asynchronous machines for receiving the data capture signal from each of the plurality of asynchronous machines. The trace synchronization system operates no slower than the data capture signal from each of the plurality of asynchronous machines, so that no data capture signals are missed.

Dependencies are inferred from the claim text.
