Custom PCIe x1 DMA Interposer Card Development -- 2

@AITSoft

Hello, I understand you need a custom PCIe x1 DMA Interposer Card that works as a go-between for a host computer and a PCIe endpoint like a Wi-Fi adapter. The card should allow the endpoint to appear directly connected to the host while embedding an FPGA with DMA capabilities to read, write, and manipulate memory and PCIe traffic. I can build the PCIe passthrough bridge ensuring protocol compliance, design the FPGA logic for bus mastering and packet injection, and integrate control through PCILeech software. The design will also include debug interfaces and optional power connectors to meet your specified form factor and power needs. My approach will focus on robust hardware design with clear control paths and high throughput DMA operations. Could you clarify which specific FPGA model you prefer or have available? What are the expected max data rates or performance targets for the DMA engine? Do you have existing PCILeech software versions or any custom modifications planned? Are there particular endpoint devices you aim to test, or should the design be generalized? What development environment or tools do you want for FPGA programming and debugging? Which FPGA model are you planning to use for this DMA interposer card? Best regards,

Hi there, I’ve carefully read your project description and I fully understand the architecture and challenges involved in designing a PCIe DMA interposer with FPGA-based bus mastering, passthrough, and packet-level control. With my background in mechatronics and advanced embedded systems, I have strong experience working on high-speed digital designs, FPGA-based systems, PCIe-related architectures, and complex PCB layouts requiring strict signal integrity, power distribution, and protocol compliance. I’m comfortable handling designs that involve DMA engines, high-speed buses, and low-level hardware/software interaction. I can help you translate this architecture into a clean, production-ready hardware design, ensuring proper PCIe routing, impedance control, power integrity, and reliable FPGA integration. I also understand the importance of clean control interfaces, debug access, and ensuring stable operation under high-throughput DMA conditions. Given my experience, I’m confident I can contribute effectively and move quickly on this project while maintaining a high level of design quality. Just send me a message and we can discuss the next steps. Best regards, Samuel Tshibangu

Hello, I hope you are doing well. I have hands-on experience designing PCIe-based FPGA systems with DMA, including custom endpoint logic, BAR-mapped control interfaces, and high-throughput data paths. I understand the complexity of maintaining transparent passthrough while injecting and managing TLP traffic without breaking enumeration or link stability. What I bring is not just schematic or HDL work, but a system-level approach covering PCIe architecture, signal integrity, FPGA resource optimization, and software interaction layers such as PCILeech integration. I can help you build a robust and debuggable design that behaves predictably under real host environments, not just in simulation. My background includes Xilinx platforms, high-speed PCB design, and low-level firmware coordination. Once you open a chat, I can walk you through similar work I have completed and how I would approach your design step by step. Best regards, Manoj Kumar A.
