Test data compression technique for embedded cores using virtual scan chains.

Test data compression technique for embedded cores using virtual scan chains.

This paper presents a design-for-test (DFT) technique to implement a "virtual scan chain" in a core that looks (to the system integrator) like it is shorter than the real scan chain inside the core. A core with a "virtual scan chain" is fully compatible with a core with a regular...
