    摘要: A software self test engine is executed from a cache of a processor. The software self test engine is executed using an execution engine of the processor to perform a physical layer self test. The physical layer self test is performed by transmitting a test vector from the execution engine under control of the self test engine to an input/output (“I/O”) unit of the processor along a datapath coupling the execution engine to the I/O unit. The test vector is transmitted along a loop back path including the I/O unit and the datapath to test a hardware device along the loop back path.

    摘要: A testing procedure for distributed logic circuits that incorporates an efficient utilization of flip-flops to toggle detect for sensing output is discussed. The distributed logic circuit is a phase interpolator or a phase interpolator preceded by a DLL. The testing procedure utilizes enabling one of a plurality of independent programmable current sources and a flip-flop to toggle in response to the enabled current source to indicate a physical connection of the enabled distributed logic circuit current source.
