4.1.2. PCIe Wake-Up Time Requirement

For an open system, you must ensure that the PCIe* link meets the PCIe* wake-up time requirement as defined in the PCI Express* CARD Electromechanical Specification. The transition from power-on to the link active (L0) state for the PCIe* wake-up timing specification must be within 200 ms. The timing from FPGA power-up until the Hard IP for PCI Express* IP Core in the FPGA is ready for link training must be within 120 ms.
