Allegro X Platform Overview

Experience The Next Generation in PCB Design with Allegro X

Key Capabilities

High-Speed Design Done Right

Reduce SI issues while routing to maximize performance and functionality with advanced high-speed capabilities in Allegro X. Auto-interactive delay and phase tune, automatic rules-based routing, timing vision with color-coded results, backdrilling support, and reusable electrical rules sets lets you quickly and successfully complete your high-speed designs.  

Automated HDI & Miniaturization

Create reliable, powerful, compact designs, and ensure HDI project success by enabling a rules-driven HDI design flow with rules for HDI spacing, stacking and micro-via insert. Additional capabilities and manufacturing rules for embedded package components guarantee overall design success and reliability.

DesignTrue DFM

Achieve first-pass manufacturing success by verifying the PCB design against manufacturer’s rules and capabilities during the PCB layout with integrated design for manufacturing (DFM) rules. The DesignTrue DFM Partner Portal and DesignTrue DFM Wizard allow engineers to quickly configure fabrication, assembly, and test constraints based on requirements direct from manufacturers to guarantee a producible, error-free PCB.

Real-Time Team Collaboration

Concurrent collaboration by team members in a single design allows designers to complete a PCB layout simultaneously. Access restrictions and a single design database eliminate the need to merge revisions and reduce errors. With embedded design review and markup, stakeholders and designers can seamlessly comment on and review the layout, streamlining the PCB design process.

Constraint Driven Design

With design complexity constantly increasing, it’s critical to employ a rule-driven design flow to ensure functionality and accuracy throughout the PCB layout. The Allegro X Constraint-Driven design methodology allows you to effortlessly manage the complicated rules required for today’s technology, including comprehensive support for timing, reflection and crosstalk, differential pairs, simultaneous switching noise (SSN), creepage and clearance, DFM, physical and spacing requirements, and more to efficiently correct the layout as you design and produce a successful PCB the first-time.

Shift-Left with EE Cockpit

Integrated stress analysis, smart schematic audits, front-end constraint management, and initial floor planning capabilities allow the EE to configure and communicate critical requirements to the PCB layout. This “EE cockpit” allows the design process to shift-left, embedding vital design information into the database, reducing PCB layout iterations, and driving the PCB design to success directly from the schematic.

In-Design Analysis

Integrate signal and power integrity analysis directly in PCB design canvas for efficient evaluation of impedance, coupling, return path, IR drop, crosstalk, reflection, power inductance, and more. Tabular results and graphical, color-coded overlays allow you to easily identify problem areas in the design, make PCB modifications, and improve signal and power integrity.
