PCIe Gen3 PHY
Maturity plannedTargets ASIC (CMOS) onlyDifficulty Very hardPriority 1
PCI Express PHY up to 8 GT/s with PIPE interface, x1 to x16 lane configurations, receiver detection, electrical idle and L1 substates. Covers Gen1 and Gen2 rates with SSC support.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
