JTAG Boundary-Scan I/O Modules
SCANIO Family - Corelis, Inc.
The Corelis family of SCANIO™ modules turn any IEEE standard 1149.1 boundary-scan controller into a powerful digital boundary-scan tester. The SCANIO family of products use boundary-scan gate arrays to add control and visibility to connectors, traces, and logic that can not be tested using traditional boundary-scan techniques.
The SCANIO products, when combined with a boundary-scan controller, operate as a traditional “bed-of-nails” tester except access to the stimulus and response I/O’s is achieved via boundary-scan.
