14.8. Design for Testability

With the push toward increased product performance and higher design complexity, the current “giant” SoCs not only incorporate multiple IP cores, they also mix diverse circuits such as digital random logic, functional units, processor cores, static memories, embedded dynamic random access memories (DRAMs), and analog circuits on a single chip. Also, new circuit types such as FPGAs, flash memories, radio frequency (RF) devices, and microwave devices are also almost at the point of becoming a regular feature of the on-chip circuitry. Zorian [618] believes that it is only a matter of time before we move beyond the realm of conventional circuits and “electronics-only” ICs and start integrating optical devices and micro-electro-mechanical ...
