Abstract: Transient voltage noise, including resistive and reactive noise, causes timing errors at runtime. A heuristic framework, Walking Pads, is introduced to minimize transient voltage violations by optimizing power supply pad placement. It is shown that the steady-state optimal design point differs from the transient optimum, and further noise reduction can be achieved with transient optimization. The methodology significantly reduces voltage violations by balancing the average transient voltage noise of the four branches at each pad site. When pad placement is optimized using a representative stressmark, voltage violations are reduced 46-80% across 11 Parsec benchmarks with respect to the results from IR-drop-optimized pad placement. It is shown that the allocation of on-chip decoupling capacitance significantly influences the optimal locations of pads.

Abstract: A medical interventional tool has distal and proximal ends. A responsive material is located at the distal end or elsewhere along the interventional tool and is capable of providing a temperature-dependent or pressure-dependent optical response. At least one optical guide is in optical communication with the responsive material to collect an optical signal from the responsive material located at the distal end or other location along the interventional tool. The at least one optical guide further guides the collected optical signal to an optical output at the proximal end of the interventional tool. An optical response analyzer is configured to receive the collected optical signal from the optical output and to process the collected optical signal to derive therefrom a temperature or pressure reading or indication representative of a temperature or pressure at the distal end or other location along the interventional tool.
