All Silicon IP


PCIe 5.0, 4.0, 3.1/3.0 Root Port, Endpoint, Dual-mode, Controller IP Core with Built-in Many-Channel DMA (vDMA), Legacy DMA, and Configurable AMBA AXI Interconnect

XpressRICH5-AXI is a configurable and scalable PCIe controller Soft IP designed for ASIC and FPGA implementation. The XpressRICH5-AXI IP is compliant with the PCI Express 5.0, 4.0, and 3.1/3.0 specifications, as well as with the PHY Interface for PCI Express (PIPE) specification and the AMBA® AXI™ Protocol Specification.

The IP can be configured to support endpoint, root port, and dual-mode topologies, allowing for a variety of use models, and exposes a configurable, flexible AMBA AXI interconnect interface to the user. The provided Graphical User Interface (GUI) Wizard allows designers to tailor the IP to their exact requirements, by enabling, disabling, and adjusting a vast array of parameters, including number, type, and width of AXI interfaces, PIPE interface width, low power support, SR-IOV, ECC, AER, etc. for optimal throughput, latency, size and power.

Users may optionally enable one of two built-in DMA engines based on the application requirements. PLDA is working hand in hand with multiple PHY IP vendors and Verification IP vendors to offer a range of integrated solutions for PCIe 5.0 at 32GT/s.

PLDA XpressRICH5-AXI PCIe IP is the #1 choice for ASIC, SoC and FPGA designers looking for an enterprise-class PCIe interface solution with a high-performance, reliable, and scalable AMBA 3 AXI/AMBA 4 AXI interconnect.


  • Internal data path size automatically scales up or down (64-, 256-, 512- bits) based on link max. speed and width for reduced gate count and optimal throughput
  • Configurable pipelining enables full speed operation on Intel and Xilinx FPGA, full support for production FPGA designs up to Gen4 x8/Gen3 x16 with same RTL code - Gen5 support pending
  • Stringent implementation of PCIe to AXI Ordering Rules and AXI to PCIe Ordering Rules guarantees AXI deadlock prevention
  • Carefully engineered AXI bridge & AXI interconnect allows full performance on AXI interfaces
  • Availability of multiple AXI Master interfaces, a key benefit for high end SSD to maximize throughput
  • Optional QuickBoot mode allows for up to 4x faster link training, cutting system-level simulation time by 20%
