QPHY-PCIE3-TxRx Limit Sets
The default installation of QPHY-PCIE 3-TxRx contains only one limit set, called “Default.” In
this script, limits are only used to convey Unit labels. The actual limits for each value tested are
encoded in or computed by the script and cannot be changed. The default limits used by QPHY-
PCIE3-TxRx are specified in the PCI Express Card Electromechanical Specification, Rev. 3.0.
