SmartDV’s CXL 4.0 Verification IP is a comprehensive solution for verifying Compute Express Link designs, an open coherent interconnect standard providing high-bandwidth, low-latency connectivity between host processors and accelerators, memory buffers, and smart I/O devices for AI, data center, and high-performance computing applications. Fully compliant with CXL Specification 4.0 and backward compatible with CXL 3.1, 3.0, 2.0, 1.1, and 1.0, it supports complete verification of CXL Host and Device components across all three CXL sub-protocols — CXL.io, CXL.mem, and CXL.cache — covering signaling rates up to 128 GT/s via PCIe 7.0, all CXL device types, Bundled Port aggregation, fabric topology, memory pooling and sharing, IDE security, and the full suite of CXL 4.0 RAS enhancements, alongside native PCIe mode operation across PCIe 1.0 through 6.0.
SmartDV’s CXL 4.0 VIP supports UVM, SystemVerilog, and Verilog, and integrates seamlessly into diverse verification environments. It is simulator-independent and compatible with all leading EDA simulators, providing flexibility across simulation platforms.
With comprehensive CXL.cache and CXL.mem request and response coverage, Type 1, 2, and 3 Multi Logical Device support, ARB/MUX link management, QoS telemetry, Advanced Error Reporting, CXL IDE key management, DOE compliance mode, built-in functional coverage, and a complete test suite, SmartDV’s CXL 4.0 VIP enables verification teams to thoroughly validate next-generation coherent interconnect designs for AI accelerators, memory expanders, disaggregated memory infrastructure, and high-performance computing applications.
