Patent number: 7702979Abstract: An object of the invention is to drastically reduce the area overhead in a semiconductor integrated circuit incorporating a test configuration that uses a partially rotational scan circuit. To achieve this, in the semiconductor integrated circuit incorporating the test configuration that comprises a combinational circuit (3) and a scan chain (2) constructed by connecting a plurality of scan flip-flops (5) in a chain, the scan chain (2) is divided into a plurality of sub scan-chains (20a to 20n) each of which has a partially rotational scan (PRS) function and a test response compaction (MISR) function. By performing a scan test in a plurality of steps while changing the combination of the sub scan-chains to be set as PRS and the sub scan-chains to be set as MISR, the test can be performed without having to provide a test response compactor separately from the scan chain, and thus the area overhead can be reduced.Type: GrantFiled: April 5, 2006Date of Patent: April 20, 2010Assignee: Semiconductor Technology Academic Research CenterInventors: Masayuki Arai, Kazuhiko Iwasaki, Satoshi Fukumoto, Takeshi Shoda, Junichi Nishimoto
