In-Design DFx, what is it?

Allegro/OrCAD In-Design DFx On-line Manufacturing Checks Not an external tool as is the prevalent industry standard of batch-mode Consistent with Allegro Constraint Driven on-line checking solution Real-time violation detection Benefits Shortens the PCB design release process Eliminates unnecessary iterations with a sign-off user Predictable design process Addresses critical DFF checks ~200+ basic checks in Allegro PCB Designer* ~1500+ advanced checks in Allegro Venture PCB Designer* Integrated in Allegro Canvas Significantly reduce dependence on Valor, enabling displacements Integrated DRC description with graphics * Based on a typical rules configuration

Traditional Manufacturing Sign-off Flow

Traditional Sign-off Flow Step 1 : Edit design - Electrical constraints build design intent Logic Schematics Placement Routing Mfg Prep Step 2 : Prepare design for sign-off - Generate output files - Gerber, NC drill, IPC-356…. - Create file package - Send to validation tool 4 to 48 hours Manufacturing Sign-off Step 3 : Run validation tools - Verify all data present - Errors found return to Step 1 Step 4 : Send to manufacturing CM / EMS

Most Common Issues found at sign-off Copper to board edge spacing Acid traps Copper slivers Annular ring

What’s wrong with this process? Most common issues are found late in the process Communication delays for issue notification Once corrected, verified again Causes delays in release to manufacturing Interruption of work in progress

In-Design DFx Capabilities

Design For Fabrication Checks Data Physical fabrication based checks only Bare board type checks. No net checks No constraint region checks Rigid-Flex zone aware Defined in Constraint Manager Import/export only manufacturing rules capability DRC Modes Analysis Online, batch, off Additional group of constraint set checks Only targeted at fabrication and assembly Independent of all other constraint driven rules Leverages multi-threading technology to enhance performance

Summary

Summary Real-time, integrated DFM solution Differentiated solution, not batch oriented Consistent with Allegro Constraint Driven design flow Addresses critical DFF needs Fewer Iterations between Design and Sign- off Reduction in release to manufacturing time Allegro with in-design DFx MO CM / EMS
