摘要： A method for determining polynomials to model circuit delay includes the step of determining one or more error areas in a characteristic map that exceed an error margin. Next, a current domain count is set to zero and selecting one error area of the one or more error areas is selected. A patch region that will contain the error area determined the patch region is then curve fitted and the current domain count is increased by one. The steps of repeating steps of selecting an error area, determine a patch, curve fitting within the patch, and increasing the domain count by one are repeated until there are no error area within the patch region. Then a previous domain region having the largest domain count and at last one error area is curve fitted without using data points in any of the domain regions greater than the previous domain region if the previous domain region contains at least one error area, repeating steps of selecting an error area, determine a patch, curve fitting within the patch, and increasing the domain count by one. Then, a domain region having at least one error area is selected as the previous domain region. The steps of curve fitting a previous domain level having at least one error area is repeated for all domain regions less than the previous domain region that has at least one error areas, until all error areas are removed from all domain regions. Additionally, the method can include using a nth order polynomial for curve fitting and associating the polynomial with the current domain region.

摘要： A method of characterizing a device under test (DUT) includes determining a goal function associated with a setup and hold time for the DUT. A minimum value for the goal function is determined by iteratively adjusting setup and hold times for input data to the DUT, and determining whether the DUT performs according to specifications. The minimum goal function value will reflect minimum setup and hold time values based on weights associated with the goal function. This allows the minimum setup and hold times for the DUT to be characterized with a small number of binary searches, improving the speed of the characterization process.

摘要： Improved message range in a wireless network is achieved by each node performing an energy/noise scan to determine a receiving channel having the lowest noise and/or interference, e.g., best reception conditions, relative to the other channels available in the wireless network. Each node may thereafter scan available channels periodically to adjust its optimal receiving channel if the noise/interference environment changes on its present receiving channel, e.g., noise/interference on another channel is less then the noise on the present receiving channel. When a receiving channel is changed by a node, the wireless node may broadcast this information to notify its neighbor nodes of the change in its receiving channel.
