Warp Pipe: Library for Simulation-Driven Development of PCIe Devices...
summary
Warp Pipe is an Apache‑licensed C library that simulates PCIe networks with tight Zephyr integration and native adapters for Qemu and Renode, enabling mixed Linux/Zephyr nodes over Unix sockets. It implements packetization and depacketization of TLP/DLLP, supports DMA and MSI, provides a Wireshark dissector for live inspection, and adds Twister integration so tests run in CI. Examples boot firmware, run performance suites (coverage ~85%) and demonstrate the model at ISS speed rather than slow RTL — it works and is upstream‑ready.
