Abstract: In a method for testing serial attached SCSI (SAS) ports of a server using a computing device, the computing device connects to an oscilloscope and a mechanical arm that is equipped with a test fixture having a probe. The mechanical arm controls the probe to be plugged into one of the SAS ports. The method adjusts an intensity grade of the SAS signals through the SAS port, and controls the SAS port to generate a SAS signal corresponding to the intensity grade. The test fixture obtains the SAS signal from the SAS port, and the oscilloscope measures test parameters of the SAS signal. The method analyzes values of the test parameters to find an optimal SAS signal, determines an intensity grade of the optimal SAS signal as a driving parameter of the SAS port, and accordingly generates a test report of the SAS ports.

The substrate includes a signal layer which is the top layer of the substrate, a first reference layer adjacent to the signal layer, and a second reference layer not adjacent to the signal layer. A first and a second pair of pads are mounted on the signal layer. Each of the through holes extends through the first pair of pads such that the through hole and the first pair of pads jointly form a compound via. A first reserved opening is formed on the first reference layer and corresponds to the first and the second pair of pads and the compound via. A second reserved opening is formed on the second reference layer and surrounds the through hole thereon.

Abstract: A computing device and a method for scattering parameter equivalent circuit reads a scattering parameter file from a storage device. A non-common-pole rational function of the scattering parameters in the scattering parameter file is created by applying a vector fitting algorithm to the scattering parameters. Passivity of the non-common-pole rational function is enforced if the non-common-pole rational function does not satisfy a determined passivity requirement.

Abstract: In a method of optimizing parameters of electronic components on printed circuit boards (PCBs), a first experiment table for m variables of one type of parameter of P electronic components on a PCB is designed using n values of each variable and the RSM. P EHs of each first experiment are obtained by simulating, and P EH empirical formulas are computed according to the P EHs. A second experiment table for the m variables is designed using n′ values of each variable and the full factorial design, and P EHs of each second experiment are computed using the P EH empirical formulas. Experiments, all the P EHs of which are greater than 1, are filtered from the second experiment tables, and an average EH of each filtered experiment is computed to pick an experiment the average EH of which is the greatest. The values of the m variables in the picked experiment are considered as optimized.

Abstract: A simulation system and method for generating equivalent circuits compatible with HSPICE reads data corresponding to N-port network system format in a storage device, and obtains S-parameter matrixes from the N-port network system. S-parameters in the S-parameter matrix that satisfy passivity are checked, and an interpolation algorithm to supplement S-parameters with passivity when some S-parameters not satisfy passivity is performed. Numbers of pole-residue, times for recursion and a tolerant system error of a rational function are generated for determining S-parameters. A rational function matrix composed of S-parameters is generated by performing a vector fitting algorithm, and an equivalent circuit is generated compatible with HSPICE format based on the generated rational function matrix.
