CXL 3.0 Verification IP

Truechip's CXL 3 Verificaton IP provides an effective & efficient way to verify the components interfacing with CXL interface of an IP or SoC. Truechip's CXL VIP is fully compliant with latest CXL specifications. This VIP is a light weight with an easy plug-and-play interface so that there is no hit on the design cycle time.

Key Benefits

  • Available in native SystemVerilog (UVM/OVM/VMM) and Verilog.
  • Unique development methodology to ensure the highest levels of quality.
  • 24X5 customer support.
  • Unique and customizable licensing models.
  • Exhaustive set of assertions, cover points with connectivity example for all the components.
  • Consistency of interface, installation, operation, and documentation across all our VIPs.
  • Provide complete solution and easy integration in IP and SoC environment.
  • On-the-fly protocol checking using protocol check functions, static and dynamic assertion.
  • Provides a comprehensive user API (callbacks). Graphical analyzer for easy debugging, regression analysis, performance, statistics, charts and automatic integration.

Features

  • Verification IP configurable as CXL Host and Device when operating in Flex Bus mode and as PCI Express Root Complex and Device Endpoint when operating in PCIe mode.
  • Support for all three CXL protocols i.e., CXL.io, CXL.cache, CXL.mem and device types to meet specific application requirements with user configurable memory size for both CXL Host and Device.
  • Support for CPI(CXL-Cache/Mem Protocol Interface) and CXS (Credited eXtensible Stream) at either side of host or device
