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.

Easily ensure test points are accessible in your designs.

Easily create and assign constraints for manufacturing based on IPC standards and common PCB rules.

Measure from true signal origin to end point through vias and through packages, not just the etch, so you can get timing right and ensure signal performance.

Running traces over voids and split planes can cause impedance and noise control issues. Signal traces must be routed over an uninterrupted copper plane to ensure continuous loop or return path current. However, by automatically identifying problem traces, you can eliminate the need for time consuming, error-prone manual scanning on every layer of the board. OrCAD helps you do this with Segment Over Void detection. Now, problem traces are reported with the click of a button and highlighted for your review.

Matching trace lengths for large-bit buses and differential pairs in your design is vital. However, this can be a tedious process and mismatched lengths can result in signal quality and integrity issues. Signals may need to be synchronized with clocks and unmatched differential pairs create additional noise. Any of these issues can be detrimental to your design. However, by automating the process you can improve signal quality and reduce time and errors, allowing you to focus on more important aspects of the design. OrCAD helps you do this with constraints for Net Groups. Create Constraints for minimum and maximum propagation delay in mils, nanoseconds or percentage. Or set constraints for total etch length. Create Net Groups and assign the constraints to all the nets in a group. Analyze the constraints without ever leaving the Constraint Manager. DRC Markers flag any incorrect lengths in real-time. Eliminate the need to check each individual net with OrCAD PCB Designer.

Prevent time-to-market delays by identifying manufacturing issues before they become a costly mistake. It’s not uncommon for designs to be submitted to manufacturing only to have problems identified that require design reworking and re-submission. This results in lost production time, schedule delays, and recurring tooling costs. What if you could identify DFM problems as you design and fix them when they happen? This webinar will help show you how to spot and fix troublesome DFM issues in-design before they ever become a problem.

An in-depth overview of OrCAD 17.2 PCB Professional

This week’s Working with OrCAD video, DRC, will discuss how OrCAD can help easily resolve DRCs in your design. The video will cover how view DRC counts, review, waive, or fix them and reports you can execute which provide a secondary set of checks.
