Abstract: IEEE 1149.1 Test Access Ports (TAPs) may be utilized at both IC and intellectual property core design levels. TAPs serve as serial communication ports for accessing a variety of embedded circuitry within ICs and cores including; IEEE 1149.1 boundary scan circuitry, built in test circuitry, internal scan circuitry, IEEE 1149.4 mixed signal test circuitry, IEEE P5001 in-circuit emulation circuitry, and IEEE P1532 in-system programming circuitry. Selectable access to TAPs within ICs is desirable since in many instances being able to access only the desired TAP(s) leads to improvements in the way testing, emulation, and programming may be performed within an IC. A TAP linking module is described that allows TAPs embedded within an IC to be selectively accessed using 1149.1 instruction scan operations.

Abstract: The Translation Layer is embedded into each circuit under test (CUT) to modularize test process. The modularized tests are self-contained and performed in isolation. They are composed without consideration of environment constraints. The CUT and its environment constraints can be concurrently be tested in isolation and independently. Interconnections between the CUT and the environment can be tested in the environment constraint test without additional dedicated test logic. The modularized test process allows the test patterns of the environment constraints to be derived from those of the CUT. The resulting test patterns are used to compose the test patterns of a target system. Since the test process is recursive in nature, the modularized test of each constituent subsystem or design core can be performed in isolation in the target system, while the environment constraints and the interconnections are being tested concurrently.

The solid-state defects in the crystal sensor absorb microwave and optical energy to transition between several energy states while emitting light intensity indicative of their spin states. The magnetic field alters the spin-state transitions of the solid-state defects by amounts depending on the solid-state defects' orientations with respect to the magnetic field. The optical read out, reporting the spin state of an ensemble of solid-state defects from one particular orientation class, can be used to lock microwave signals to the resonances associated with the spin-state transitions. The frequencies of the locked microwave signals can be used to reconstruct the magnetic field vector.
