Latest Patents

Kanei's latest patents include a "Power Supply Noise Analysis Model Generating Method" and a "Power Supply Noise Analysis Model Generating Apparatus." The objective of these inventions is to simplify the power supply noise analysis model of a circuit board. By obtaining CAD data from a CAD apparatus, overlapping power supply islands among different layers of the circuit board are extracted as a power supply pair. Nodes are arranged in this extracted power supply pair, and the nodes are projected onto the corresponding power supply islands. A mesh region is determined for each power supply island, and the impedance (L, R, C) between nodes is calculated. This leads to the creation of a power supply noise analysis model based on the impedance between nodes in each layer and the capacitance between layers.

Another significant invention is the "Noise Checking Method and Apparatus." This invention aims to enhance the accuracy of noise calculations and checks during electronic circuit design. The noise checking apparatus includes a model production section for creating a simulation model of a circuit portion related to a specific wiring line. It also features a simulation section that calculates signal and noise waveforms, a noise waveform synthesis section for combining these waveforms, and a noise checking section for performing noise checks based on the synthesized waveforms.
