2. 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)
