What does SI Service Include?

Axcon offers signal integrity service on many different levels. Basically, this includes support of and throughout the entire process, from concept and architecture to the following testing and verification steps. A typical process involves both the circuit designer and the layout person, to varying extends. The process can for instance involve the following issues:

• Choice of connection technologies during system design.
• Analysis of package types in relation to choice of components.
• Collect and control of necessary IBIS/Spice models for simulation.
• Choice of PCB stack-up.
• Identification of interfaces and definition of net classes.
• SI analysis (simulation) of net classes for all interfaces.
• Formulation of routing rules for all net classes (layers, lap width/impedance, distance in class, distance to other classes, via-restrictions, length restrictions etc.)
• Transfer of schematic, net list and routing rules for the layout system.
• Assistance with and follow-up on layout with auto-routing run by rules.
• Adjustment of routing rules for optimum utilization of resources and auto-router.
• Control of finished layout in relation to routing rules prior to PCB production.
