PCB Design Automation Stackup - Build/Check/Compare Constraint - Build/Check/Compare Checklist – Check/Prompt/Record 6/6/2018

Purpose 1. We require an easier and faster way to create and verify PCB Design layer stackups and impedance values. (Completed) 2. We require a faster and easier way to add and verify signal constraints in the PCB Design database. (In-work) 3. We require a faster and easier way to check the PCB Design database prior to fabrication. (In-work)
