XpressRICH4

PCIe 4.0, 3.1/3.0 Root Port, Endpoint, Dual-mode, Switch Port Controller IP Core with Native User Interface

XpressRICH4 is a configurable and scalable PCIe controller Soft IP designed for ASIC and FPGA implementation. The XpressRICH4 IP is compliant with the PCI Express 4.0 and 3.1/3.0 specifications, as well as with the PHY Interface for PCI Express (PIPE) specification. The IP can be configured to support endpoint, root port, switch port, and dual-mode topologies, allowing for a variety of use models. 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 data path size, PIPE interface width, low power support, SR-IOV, ECC, AER, etc. for optimal throughput, latency, size and power. XpressRICH4 IP is verified using multiple PCIe VIPs and testsuites, and is proven in production silicon in hundreds of designs using a variety of commercial and proprietary PCIe PHYs. PLDA XpressRICH4 PCIe IP is the #1 choice for designers requiring enterprise-class features, highest performance, reliability, and scalability.

XpressRICH4 controller IP is integrated, validated, and silicon-proven with a variety of PCIe PHY IP covering PCIe 4.0, 3.1, 2.1, 1.1, and process nodes down to 7nm. Supported combos include PHY IP from our Partner Ecosystem, PHY IP from EDA vendors Synopsys and Cadence, PHY IP from leading edge ASIC vendors, and integrated PHY Hard IP from FPGA vendors Intel (Altera) and Xilinx.

Some of our proven PCIe 4.0 Controller-PHY combos include:

  • Avago PHY on TSMC 16FF/FF+, 7FF
  • Cadence PHY on TSMC 28
  • Phison PHY on TSMC 28HPC+
  • Rambus PHY on TSMC 28
  • Synopsys PHY on TSMC 28HPC+
  • Terminus Circuit PHY on TSMC 28HPC
  • Xilinx Virtex UltraScale+ integrated PHY

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

Check out our Integration Services page for more information on our ADI team and its capabilities.

  • Xilinx 7-series and UltraScale series: up to Gen3 x8
  • Xilinx UltraScale+ series : up to Gen4 x8 or Gen3 x16
  • Altera V-series (Arria, Stratix): up to Gen3 x8
  • Altera 10 series (Arria, Stratix): up to Gen4 x8 or Gen3 x16

Note that the number of ports that can be implemented on FPGA is limited by the number of transceivers/quads available on the targeted device.

PCI Express layer

  • Compliant with the PCI Express 4.0 and 3.1/3.0, and PIPE (8-, 16- and 32-bit) specifications
  • Compliant with PCI-SIG Single-Root I/O Virtualization (SR-IOV) Specification
  • Supports Endpoint, Root-Port, Dual-mode, Switch port configurations
  • Supports x16, x8, x4, x2, x1 at 16 GT/s, 8 GT/s, 5 GT/s, 2.5 GT/s speeds
  • Supports AER, ECRC, ECC, MSI, MSI-X, Multi-function, crosslink, and other optional features
  • Additional optional features include OBFF, TPH, ARI, LTR, IDO, L1 PM substates, etc.

User Interface layer

  • 256-bit transmit/receive low-latency user interface
  • User-selectable Transaction/Application Layer clock frequency
  • Sideband signaling for PCIe configuration access, internal status monitoring, debug, and more
  • Optional Transaction Layer bypass

Download the product brief or request the reference manual for complete specification and additional information.

  • Internal data path size automatically scales up or down (64-, 256- bits) based on max. link speed and width for reduced gate count and optimal throughput
  • Dynamically adjustable application layer frequency down to 8Mhz for increased power savings
  • Optional MSI/MSI-X register remapping to memory for reduced gate count when SR-IOV is implemented
  • 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
  • Ultra-low Transmit and Receive latency (excl. PHY)
  • Smart buffer management on receive side (Rx Stream) and transmit side (merged Replay/Transmit buffer) enables lower memory footprint
  • Optional Transaction Layer bypass allows for customer specific transaction layer and application layer
  • Optional QuickBoot mode allows for up to 4x faster link training, cutting system-level simulation time by 20%

The XpressRICH4 controller IP is integrated and thoroughly verified using multiple VIP for foolproof reliability. We use a combination of Avery VIP, Cadence VIP, and Mentor VIP, and PCIe testsuites to achieve optimal coverage.

We use state-of-the-art FPGA prototyping platforms built in-house to thoroughly validate XpressRICH4 controller IP in real world conditions.

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