Allegro X is Cadence’s platform for complex hardware designs. It is built for systems with multiple PCBs, for teams working on the same design simultaneously, and for requirements that must be managed as constraints rather than as agreements.

PORTFOLIO
Two tools carry the core work. The other two ensure that a large design stays on track throughout the process.
Schematic · System and Circuits
From the system architecture to the individual schematic. Designed for projects consisting of more than one PCB.
Layout · Routing and Physics
The layout environment for high-density, high-speed PCBs, with active rules and analysis integrated into the layout.
Constraints · unified rules
Constraints managed in one place, applied across both schematic and layout, and reusable for your next project.
Analysis · in progress
Signal and power integrity analysis performed on the layout using Sigrity X Aurora.
HOW IT CONNECTS
Constraint Manager keeps the rules organized so that they apply to both the schematic and the layout. That is the difference between a documented requirement and one that has been agreed upon.
A large PCB doesn't have to wait for one person to finish. Multiple people can work on it at the same time, keeping track of who is changing what.
Signal and power integrity are addressed during the routing process, rather than as a separate project afterward.
SEE IT IN ACTION
The video provides an overview of the Allegro X platform through short clips from day-to-day work, from schematics to layout and analysis.
If you'd like to see how it fits with your designs, we'd be happy to go over it with you and one of our specialists.
THE FULL SUITE
COMPARE
OrCAD X Professional covers the vast majority of PCBs, including high-speed and rigid-flex PCBs. The difference becomes apparent when the design consists of multiple PCBs, becomes very dense, or when a more in-depth analysis is required.

CUSTOMERS
Development teams working on complex designs in Allegro X alongside Nordcad.
We quickly identified many low-hanging fruits to streamline the process. Nordcad has been responsive and expert in delivery — and has helped us automate output, ensuring consistent results every time.
With Allegro X, we can significantly shorten the development cycle—we quickly assess density and complexity and adjust the electrical design as we go.

Ready?
A brief conversation is usually enough to determine whether your designs are the kind where Allegro X makes a difference. No sales pitch. No pressure. Just an open discussion about the PCBs you’re making and how many of them there are.
FREQUENTLY ASKED QUESTIONS
OrCAD X is the all-in-one package for a team that designs the PCB from start to finish on its own. Allegro X is built for larger-scale projects: multiple PCBs in the same system, multiple people working on the same design at the same time, and high-speed designs where requirements must be managed as constraints. The table above shows the differences, and we’d be happy to review your designs before recommending one solution over the other.
It depends on the design, not on the size of the company. A small team working on a single high-speed PCB may benefit more from Allegro X than a large team working on simple PCBs. That’s also why we’d rather look at one of your designs than an organizational chart.
Yes. The two platforms share the same core technology, and data can be transferred seamlessly. Many begin with OrCAD X and migrate as their designs grow.
Yes. In-design analysis in the layout is powered by Sigrity X Aurora. Deeper analysis in PowerSI and Advanced SI are standalone tools that can be added later.
Yes. Allegro X can be rented on a weekly, monthly, quarterly, semi-annual, or annual basis, and it can also be purchased. This allows you to test the platform on a specific project before making a decision.
