Contributions With Source


Contributed Reuse Library


  • Cadence oaScan : Binary and Documentation
    oaScan is an unlicensed application that scans the contents of a library and checks for inconsistencies in the OpenAccess design, tech and DMData databases. Optionally, oaScan can repair the inconsistencies and save the databases. Inconsistencies are more common with older versions of OpenAccess. The oaScan application is used to upgrade such data to current quality standards.
