Constraint-Driven Design

Manage Design Intent Direclty Inside Your CAD Environment

Native Constraint Management

As designs become more complex, the number of constrained and managed nets continue to increase. Keeping track of the growing number of rules that need to be adhered to can become a serious design challenge. Without a constraint-aware CAD environment, design teams are forced to spend an extensive amount of time checking their design against their rules manually or risk sending a bad design to production.   

Common Constraint Management Issues

  • CAD data and constraints are stored separately.
  • Extensive time is spent verifying designs based on external constraint requirements.
  • Inability to define constraints properly inside native CAD tools.
  • Constraint checking does not occur in real-time.
  • Inability to derive design intent from actual simulation results.

Benefits of a Constraint-Driven PCB Design Environment

Complete Constraint Environment

Embed your design intent directly into your CAD data at both the schematic and PCB stage ensuring everyone will stay in sync seamlessly.

Intuitive Constraint Entry

Simple, spreadsheet-based interface makes it easy to enter and manage constraints throughout the design process.

Simulation Driven Rules

Avoid overly restrictive design rules. Define constraints directly from simulation results to optimize design requirements for your unique design needs.

Real-Time Feedback

Real-time DRC engine provides immediate constraint pass/fail feedback as the design progresses, enabling designers to make quick adjustments on the fly.

Comprehensive Verification

Quickly analyze the entire design and generate reports to ensure all constraints are being met before signoff.

Evaluate in Context

View requirements in the context of the design itself, easing the design review process.
