The Cadence® Allegro® PCB SI furnishes an integrated high-speed design and analysis environment for engineers creating complex digital PCB systems. This family of products in the Allegro system interconnect design platform allows users to develop optimum constraints very early in the design cycle. It also enables a constraint-driven PCB design flow. The result is first-pass success for even the most complex designs.
Allegro PCB SI offers the scalability to design anything from PCB systems with large number of high-speed nets to systems having a small number of nets that operate in the multigigahertz (MGH) range. This integrated analysis environment allows SI and hardware engineers to explore and resolve electrical performance-related issues at every stage of the high-speed PCB system design cycle.
As timing margins shrink, it is important to consider the effects of discontinuities on the signal path, whether they are inside the package or within the system of multiple boards. The Allegro PCB SI solution performs analysis on the board, across multiple boards, or across silicon-package-boards. Its ability to read the Allegro Package Designer database and use actual signal lengths inside a critical IC package enables users to fine-tune critical signals on the PCB.
Allegro PCB SI Silicon Design-in Kits
Cadence pioneered the concept of silicon design-in kits—introducing the first Allegro PCB SI silicon design-in kit for Intel's 64-bit architecture in 1998—and continues to lead the industry in providing this type of complete EDA solution. Silicon design-in kits contain validated models, topology files, layout constraints, example PCB files and footprints, tutorials, documentation, scripts, and other utilities. |
