Technical Examples

A multi-level scan compression method and apparatus for reducing test data volume and test application time in a scan-based integrated circuit without reducing the speed of the scan chain operation in scan-test mode or self-test mode. The scan-based integrated circuit contains one or more scan chains, each scan chain including one or more scan cells coupled in series. Two or more decompressors are embedded between N compressed scan inputs and M scan chains, where N<M, to broadcast compressed scan data patterns driven through the N compressed scan inputs into decompressed scan data patterns stored in the M scan chains. The multi-level scan compression approach allows to speed up the shift-in/shift-out operation during decompression using two or more decompressors separated by intermediate scan chains. Two or more compressors are separated by intermediate scan chains to speed up the shift-in/shift-out operation during compression.
