PCIe Software Developer
Project description
We're looking for a PCIe Developer to join our team.
Responsibilities
- * Design and develop PCIe controller features using modern C++ * Implement PCIe transaction layers, data path logic,MAC layer, protocol handling, and error recovery mechanisms. * Work closely with hardware/RTL teams on PCIe IP integration, debug, and bring-up. * Develop and maintain PCIe TLP/ DLLP/ LTSSM handling modules. * Contribute to the development of drivers, firmware modules, or board-level diagnostics for PCIe devices. * Implement performance improvements including latency reduction, throughput optimization, flow control tuning, etc. * Participate in post-silicon validation, debugging link training issues, and compliance interoperability problems. * Build unit tests, system tests, and simulation testbenches for PCIe components. * Collaborate with cross-functional teams including Silicon, FPGA, Validation, and Firmware.
SKILLS
Must have
- * 5-8 years of experience * Strong C++ programming experience. * Hands-on PCIe development experience (not just usage): - TLP formatting and parsing - Data link layer concepts - LTSSM understanding - Flow control mechanisms - Virtual Channel (VC), Traffic Class (TC), Completion rules - MSI/MSI-X, BARs, configuration space access * Experience developing or debugging PCIe controllers, endpoint or root complex. * Strong understanding of PCIe Base Spec (Gen6). * Experience with logic analyzers, PCIe protocol analyzers, or hardware bring-up. * Good understanding of low-level system concepts: DMA, MMIO, interrupts, caching, coherency. * Experience in Linux/Windows system programming is a plus. * Strong problem-solving skills in a real-time embedded or system-level environment.
Nice to have
* Exposure to PCIe Gen5/Gen6, SR-IOV, ATS, PASID, PRI, IDE * SystemC knowledge
