Signal Integrity

Signal Integrity (SI) has become a de facto measure of PCBA EDA tool effectiveness. Numerous tools over the last 30 years have been built to generate PCBAs. Only a select few, typically with great effort, have provided effective solutions to the SI challenge.

JITX provides an SI solution that tackles many of the most difficult tasks in SI routing while maintaining consistency across large designs. The use of code to define constraints is a super power in this context. As we define the structures in a high frequency design, JITX can enforce design rules that are not possible in other tools. These aren't after the fact checks - these constraints influence the synthesis of the SI routes on the board in real time.

These constraints come in the form of primitives that provide the basic features. We then provide a high-level library in the form of JSL to more productively leverage those primitives.

This series outlines JITX's SI solution, including:
