PCIe Gen4 controller (EP/RP)
Maturity plannedTargets FPGA + ASICDifficulty Very hardPriority 2
PCI Express controller up to Gen4 operable as endpoint or root port, with transaction, data link and PHY logical layers, SR-IOV option and a PIPE interface. Adds 16 GT/s, lane margining and extended tags and credits.
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.
