CXL Verification IP

Features

• Compliant with the CXL 1.1 specification.
• 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 CXL Downstream and CXL Upstream Port registers (located at RCRB and MEMBAR0).
• Support for 32.0 GT/s Data Rate with backward compatibility.
• Support for Alternate Protocol Negotiation for CXL Mode.
• Support Pipe Specification 5.1 with both Low Pin Count and Serdes Architecture.
• Support for ARB/MUX for CXL ALMP transmission and reception to control virtual link state machine and power state transition requests.
• Support for CXL ACK forcing and Link Layer Credit exchange mechanism.
• Support Arbitration among the CXL.IO,CXL.cache and CXL.mem packets with Interleaving of traffic between different CXL protocols.
• Support for randomization and user controllability in flit packing.
• Support for CXL Link Layer Retry Mechanism.
• Support for Configurable timeout for all three layers.
• Support for different CXL/PCIe Resets.
