    Abstract

    Asynchronous circuits offer great potential for solving the interconnect problems faced by system-on-chip designers, but their adoption has been held back by a lack of methodology and support for fabrication testing of such circuits. This paper addresses this problem using a partial scan approach which achieves a test coverage of 99.5% on the CHAIN network-on-chip interconnect fabric which is used as an example. Test patterns are generated by a custom program automatically, given the topology of the interconnect. In comparison to standard, asynchronous, full-scan LSSD methods, area savings in the order of 50% are noted.
