XpressRICH5-AXI

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. 

We are actively working with our PHY ecosystem partners to provide an integrated and validated PCIe 5.0 controller + 32G PHY solution on a variety of process nodes and for a variety of foundries, as well as on leading edge FPGAs from Intel PSG and Xilinx.

Our unmatched expertise in PHY integration means customers can confidently select the PHY IP that best fit their requirements.

PCI Express is a complex protocol, and customers may not always have the expertise, the resources, or the time required to meet their development schedule. Our Advanced Design Integration (ADI) team helps customers shorten their development cycle by proposing expert services in the following areas:

  • Integration of commercial and proprietary PCIe PHY IP
  • Development and validation of custom PCIe PCS layer
  • Customization of the PCIe IP to add customer-specific features
  • Generation of custom reference designs
  • Generation of custom verification environments

  • 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%

The XpressRICH5-AXI controller IP is integrated and thoroughly verified using multiple VIP for foolproof reliability. We use a combination of Avery VIP, Cadence VIP, Mentor VIP, PCIe testsuites, and a PLDA-developed verification environment to achieve optimal coverage.

Our rigorous verification process ensure customers can focus on the core of their application.
