ɢ How to Use:
■
Run signal integrity simulations on critical nets, focusing on differential pairs, clock lines, and data lines. Review eye
diagrams, then make routing adjustments in Presto PCB Editor.
■
Identify sources of reflections or crosstalk in Sigrity X Aurora, using simulation results to refine trace placement and
spacing.
Practical Tips for Manufacturing Handoff
f
Communicate High-Speed Constraints: Include a summary of high-speed requirements with the manufacturing files, such
as trace width tolerances and controlled impedance specifications.
f
Review Gerber Files with the Manufacturer: Coordinate with your manufacturer to review the Gerber files and ensure that
all high-speed requirements and DFM/DFA adjustments are understood and achievable with their equipment.
f
Document Assembly Guidelines: For DFA, include notes on component orientation, assembly order, and any special
instructions for placing high-speed components like BGAs or connectors.
