PCIe GND Via fanout location: does it matter where?

PCIe is a vastly used High-Speed interface.

However, routing PCIe signals and passing compliance simulations and performance tests are more challenging than one can think.

Check out a simple, good practice rule of thumb to improve PCIe SI performance dramatically.This video is based on an internal training session for the Dgtronix HW designers.

Keysight ADS SI tools were used for this Test Case.
