The detection of catastrophic short and open faults in bipolar current mode logic (CML) circuits is studied. The non-intrusive tests considered include functional (logic) tests, an Idd test, and a common-mode test. A 622 Mbps SONET SIPO (Serial-In/Parallel-Out) and a PISO (Parallel-In/Serial-Out) circuit form the basis of this case study
