Compression of emulation trace data |
摘要 |
A system and method for compressing trace data from an emulation system. Scan chains may receive trace data from configurable logic blocks inside one or more emulation chips, and the data received from the scan chains may be compressed. Where delta compression is used, the scan chains may also perform a delta detection function. Alternatively, delta detection may be performed using the outputs of the scan chains. In addition, event detectors may be implemented within or outside of the scan chains. Compression of the trace data may include receiving a plurality of data sets and performing compression along cross-sections of the combined data sets.
