Abstract: For a circuit path to be represented in a timing model, a set of propagating waveforms substantially converges through waveform stabilization to a uniform waveform at a waveform invariant node and all pins following. The circuit path is decomposed at the waveform invariant node into first and second portions, which are characterized as first and second timing arcs. In computing output slew and delay values, the first timing arc generation factors only a single output load of the waveform invariant node, and the second timing arc generation factors only the uniform waveform. Similarly, a setup arc employs the uniform waveform rather than multiple clock input waveforms in computing setup/hold values. Simulation of waveform propagation is also simplified by simulating only the uniform waveform for the second portion. Additionally, the first arc may be shared between a plurality of circuit paths which share an input pin and the waveform invariant node.

Abstract: Methods, systems, and apparatuses for wireless communication are described at a device. A device may utilize telescopic discovery techniques to efficiently preserve a wireless connection until a previously connected device returns within range of the connection. In one example, the device may transmit a discovery request intended for the other device according to a first interval after determining the wireless connection. If a response is not received, the device may adjust the transmission interval to be a second interval. The device may then compare the second interval with a maximum interval to determine whether the second interval is greater than the maximum interval. If the second interval is less than the maximum the device may transmit a discovery request according to the second interval. Otherwise, the device may transmit discovery requests according to the maximum interval until a discovery response is received from the other device.
