  # CXLMemSim
  
  CXLMemSim is a software framework for studying CXL memory systems without requiring complete CXL hardware. The repository contains two related pieces:
  
  - a CXL memory latency, bandwidth, topology, and coherency simulator.
  - a QEMU-integrated CXL emulation stack for Type 3 memory devices, distributed memory pooling, and experimental Type 2 accelerator/GPU support.

  # CXLMemSim: Cycle-Accurate CXL 3.0 Memory System Simulation and QEMU Emulation
  
  CXLMemSim is the leading open-source framework for cycle-accurate performance simulation and characterization of CXL 3.0 memory systems. It uniquely integrates a detailed CXL memory latency, bandwidth, topology, and coherency simulator with a QEMU-based CXL emulation stack for Type 3 memory devices, distributed memory pooling, and experimental Type 2 accelerator/GPU support. This enables full-system experiments for hardware architects and researchers without requiring complete CXL hardware.

  ## Why CXLMemSim?
  
  Unlike general-purpose simulators or high-level EDA tools, CXLMemSim offers a unique combination of:
  
  - **Cycle-Accurate CXL 3.0 Simulation:** Detailed modeling of CXL.mem protocol, latency, bandwidth, and coherency for precise performance characterization.
  - **QEMU-Integrated Emulation:** Seamless integration with QEMU for full-system experiments, allowing guest software to interact with realistic CXL device interfaces.
  - **Comprehensive CXL Feature Support:** Includes Type 3 memory devices, distributed memory pooling, and experimental Type 2 accelerator/GPU support, providing a robust platform for CXL research and development.
