The electronics industry has been developing rapidly driven by Moore's Law, with enhanced product functions, higher integration, faster signal rates, and shorter development cycles. As electronic products continue to become more miniaturized, precise, and high-speed, high-speed channel design must consider the complete communication chain from the transmitter, vias, connectors, and transmission lines to the receiver. It is also essential to support accurate simulation of the IBIS model, AMI model, transmission line model, and S-parameters. The traditional SPICE time-domain simulation method struggles to ensure accuracy and convergence of S-parameters and transmission line cascades in multi-port situations.
PCB board design is a complex process that involves a transformation in design concepts, approaches, processes, and methods due to signal integrity issues, including signal crosstalk. As an essential part of electronic systems, PCB board design is not only about connecting components through circuits. It also needs to consider high-speed, high-density, and the correctness of electrical rules in thermal and electromagnetic design fields.
Xpeedic PCB board design tool solves challenges encountered in product design, such as signal integrity, power integrity, and radio frequency system optimization. The solution includes electronic design automation for chips, packaging, circuit boards, components, and systems within the electronics industry, to determine whether the design meets the requirements. The design can be quickly optimized without spending a lot of time building and testing costly prototypes. It can model and simulation more conveniently and accurately, assisting designers quickly check critical path signal integrity indicators, like insertion loss, return loss, eye diagrams, ISI, and crosstalk. The tool uses industry leading frequency-domain cascading technology to achieve cascading multiple S-parameters quickly and accurately. It can be integrated with Notus to extract the equivalent topology of the network. Embedded with leading time-domain simulators, the tool supports the latest versions of IBIS and AMI model simulations, including NRZ and PAM-4 modulation modes, equalization and pre-emphasis technology, drawing PAM-4 eye diagrams, and automatic extraction of PKG parameters.
