CXL - Enables robust testing of CXL-based systems for performance and reliability

Overview

CXL Verification IP is a cutting-edge solution for validating designs based on the Compute Express Link (CXL) protocol. With features like protocol compliance checks, cache coherency validation, and advanced debugging tools, it ensures robust and efficient testing of high-performance computing systems.

From HPC and AI to automotive and edge computing, CXL Verification IP supports diverse applications. It enables seamless communication between processors, memory, and accelerators, ensuring reliable performance in data centers, ML systems, cloud infrastructures, and telecom networks.

Key Features

  • Protocol Compliance: Ensures strict adherence to CXL 1.1, 2.0, and 3.0 standards, with automated checks to validate protocol correctness and ensure interoperability. This provides confidence that systems meet the latest CXL specifications and can communicate seamlessly across devices.
  • Cache Coherency Validation: Verifies that memory is consistently shared and synchronized across different processors and accelerators, preventing data inconsistencies. This ensures that cache coherence is maintained for efficient multi-core or multi-processor system performance.
  • Multiple Protocol Modes: Supports I/O, Memory, and Cache modes, allowing for versatile testing across different CXL operational modes. This ensures comprehensive validation of systems using various types of data transfer and memory access, depending on the mode of operation.
  • Advanced Error Injection: Simulates real-world errors, such as data corruption or link failures, to test error detection and recovery mechanisms. This helps ensure system robustness and reliable operation even in the presence of faults.
  • High-Speed Data Transfer: Validates data transfer rates up to 64 GT/s, ensuring the system can handle high-performance, high-bandwidth communication essential for modern designs. This is critical for applications requiring extremely fast data throughput, like AI and high-performance computing.
