PCIe 4.0 Host Enabling Reference Platform for Prototyping &
Development of PCIe 4.0 Devices and Applications 


PLDA Gen4HOST provides a platform for prototyping and developing PCIe 4.0
hardware and software. At the core of Gen4HOST is PLDA's PCI-SIG compliant
XpressSWITCH switch IP for PCIe 4.0 technology running on a Xilinx® Virtex®
UltraScale+™ FPGA. Gen4HOST provides a PCIe 3.0 x16 (upstream) to PCIe 4.0
x8 (downstream) integration backplane for development and validation of PCIe
4.0 endpoints, and is also available in a reversed configuration (PCIe 4.0 upstream,
PCIe 3.0 downstream) for development and validation of PCIe 4.0 Hosts and Root
Complexes. By working with Gen4HOST, early developers of PCIe 4.0 devices can
accelerate their software, firmware, and hardware developments, in their production
environment, using the Operating System of their choosing.
