The board design phase is probably the longest step in new product introduction. Cadence® Allegro® technology helps you to shorten your overall design process by improving individual and team productivity, as well as minimizing rework by bringing more and more of the post-design verification and analysis process into the early design stages.
Allegro PCB DesignTrue DFM Technology
Manufacturability is a fundamental requirement for all your designs. Ultimately, the burden of making a design manufacturable lies with the PCB designer, regardless of who is responsible for manufacturability. Allegro PCB DesignTrue DFM Technology brings more than 2,000 real-time manufacturability rule checks into the design environment, minimizing rework and easing new product introduction.
Integrated Manufacturing Constraints
Manufacturing rules are managed as constraints in the familiar constraints manager, coexisting independently with electrical rules that can have more or less constrictive constraints.
Real-Time DFM Verification
The design canvas shows design for manufacturing (DFM) check violations in real-time while designing, because the best time to find and fix errors is now, not later.
Signoff with Confidence
Double-check your DFM rules before signoff with a forced batch check of all rules for your whole design. If you do find something awry, it’s easy to locate and fix in your design.
Actionable Analysis Results for PCB Designers
PCB design is where the science of signal integrity goes from theoretical to real. By bringing actionable analysis results to the PCB designer–in their own environment–the Allegro technology helps designers complete complex designs faster by minimizing post-analysis rework.
Return Path Checks
Easily identify potential return path issues, like crossing a split plane or changing reference planes in real-time while you design, without waiting for the signal integrity engineer to perform analysis and provide feedback.
Impedance Analysis and Vision
Trace segments or parts of a segment are color coded to show impedance discontinuities based on analysis of where the reference plane is located. Segments are color coded to reflect if the impedance is above, below, or meets the impedance constraints.
Coupling Analysis and Vision
Coupling analysis and vision provides a view of where crosstalk issues may occur. Visual feedback on where higher coupling is occurring and who the aggressor is allows PCB designers to reduce iterations with signal integrity (SI) and power integrity (PI) engineers. Hovering over a trace gives designers detailed information needed to resolve the issues.
Static Phase Check at a Via Transition
Cline segments are color-coded to show which trace segment between pins and vias is out of phase, eliminating the guesswork and trial and error.
Allegro PCB Symphony Team Design Option Real-Time Concurrent PCB Design Collaboration
The way we collaborate is changing. Everyone is hyper-specialized and spending expert engineering resources where they can make the most impact is one aspect of making sure your team is running at peak efficiency. Allegro PCB Symphony Team Design Option supports collaborative placement, routing, auto-interactive routing, interactive routing, and shape design to let your team dedicate their time and efforts to get designs done faster through real-time concurrent design collaboration.
Real-Time Concurrent PCB Design Collaboration
Local and dispersed teams can collaborate in real time on a single design and instantly see the changes being made by their teammates. Conflicts are easily avoided by restricting access to an object or objects being edited by a user, dramatically reducing routing time and eliminating the need to merge multiple versions.
Managed Constraint Manager Controls
A single user can have exclusive access to define or update constraints through the constraint manager while all other members continue to design in a constraint-driven flow.
Interactive3D Canvas with Rigid-Flex and Seamless Mechanical Collaboration
Your products all have three dimensions. And viewing them in 3D is great, but going back and forth from a 2D design and a 3D visualization feels a lot like trial and error. Don’t just view in 3D; design in 3D with the Allegro Interactive3D canvas.
3D Bending of Flex Material
Bend flex circuitry in your design individually or in groups to verify assembly and fit, and see any collisions that may be happen when folded.
3D Component Placement and Movement
Move and place components in 3D, where it’s easiest to find and fix collisions.
Seamless ECAD/MCAD Collaboration
Product design is a collaborative, often iterative, process between multiple domain experts. It’s a delicate balancing act of maintaining the divide between domains of expertise, but allowing for smooth collaboration.
Advanced Routing Features
PCB routing is where designers spend the majority of their work day. Productivity, teamwork, and right-the first-time accuracy are the best ways to shorten your overall design time.
Always cross your “t’s” and dot your ”i’s.” Clean up and optimize traces for spacing and balance, functionality, and manufacturablity with one quick look, an easy way to improve performance and yield.
Automatically center individual routes between via and pin channels, and evenly space between multiple routes for clean and neat routes when hugging and shoving.
Route Clearance View
Avoid rejection—visualize object- and route-spacing constraints while routing to know if a trace will fit before attempting.
Reusable inductance compensation structures, or L-Comp structures, increase pin inductance to reduce socket capacitance. Place reusable parameterized structures to easily achieve required capacitance.
