Problems solved by technology

While several algorithms are available to model the complex shape of PGPP, these algorithms are computationally expensive, especially as these PI analysis tools must share computational resources with other design tools
[0006] Unfortunately, designers encounter shapes and configurations that are often Figure 1A The simple PGPP shown is far more complex
For example, gaps, voids, cutouts, and seamed power, ground, and signal vias can cause additional problems for designers of specific circuits

Abstract

The invention relates to a method and system for PDN (Power Delivery Network) analysis. The invention aims at a computer implementing method for displaying one or more results of the PDN analysis associated with an electronic circuit design. The method can comprise the step of extracting the EM (Electromagnetic) model of each of one or more discontinuous structures associated with the electronic circuit design with at least one processor. The method can further comprise the step of executing the PDN analysis for the electronic circuit design, wherein the PDN analysis comprises a calculation by an MoM (Method of Moment). The method can further comprise the step of displaying a three-dimensional image of one or more results describing the PDN analysis. Many other features are also within the scope of the invention.

Description

technical field [0001] The present invention relates to printed circuit board (PCB) design and analysis. More specifically, the present invention relates to power delivery network (PDN) analysis, which can occur prior to fabrication of actual integrated circuits (ICs). Background technique [0002] PDN analysis including power integrity (PI) and IRDrop has become the focus of circuit designers. These tools allow simulation and modification of power distribution networks during both design and verification phases. When performing PDN analysis, the frequency response of the PDN may be analyzed. Designers can also perform static and dynamic IRDrop analysis in the time domain during the verification process. The use of PDN analysis tools may allow modifications to the design during the design phase and prior to fabrication of the actual circuit. This can significantly reduce the time to market for a given product. [0003] For example, split-plane power distribution is a co...
