The Mission of SIL is as follows.
Ensure high-speed signal quality.
Reduce PCB turn-around time to fix SI, PI
and EMC issue in advance.
Minimize cost on board design (size, layer
no.,stackup, etc ).
Provide board stack-up design and PCB
material selection.
Export layout guidelines of high-speed
signals.
Signal validation and correlation.
