✅ Hi there, I’m an FPGA/RTL engineer with solid experience on Zynq (Vivado, Verilog) and secure peripheral interfaces, including timing-sensitive single-wire buses and on-chip crypto/authentication flows. From your description, the key here is a robust 1-Wire master that respects all timing margins, plus a clean SHA-1 authentication path that matches the secure EEPROM’s command set and challenge/response protocol, all wrapped so it’s easy to use from the ZedBoard’s PS side. ✨ Here’s how I’d approach it: • Study the exact 1-Wire secure EEPROM datasheet (commands, timing, SHA-1 flow) • Implement a Verilog 1-Wire master FSM with precise timing (reset, presence, read/write slots) • Add SHA-1 authentication handling per device spec (challenge, secret, MAC verify) • Integrate with Zynq (top module + simple register/AXI-lite interface) and provide a testbench • Deliver a small Vivado project or example design to prove it on ZedBoard You’ll receive well-commented Verilog, testbenches, constraints, and a short usage guide so you can drop it into your design with minimal friction. ❓ A couple quick questions: • Which exact 1-Wire secure EEPROM part number are you using (e.g. Maxim DS28xxx)? • Do you want SHA-1 done purely in FPGA logic, or is PS-side support acceptable? Thanks for considering my bid.

### => FPGA DEVELOPMENT FOR 1-WIRE EEPROM INTERFACE WITH ZYNQ ZED BOARD <= ### Hi There, I’ve read your post carefully and I’m confident I can help you develop the Verilog code for interfacing the 1-wire secure EEPROM with your Zynq Zed Board. I’ve previously worked on FPGA projects involving low-level hardware interfacing, including integrating SHA-1 authentication protocols and ensuring full compatibility with embedded systems like the Zynq family. Here’s my approach: - Develop fully functional Verilog code to interface with the 1-wire EEPROM, ensuring correct data transfer. - Implement SHA-1 authentication handling in the Verilog code to protect data integrity. - Test and optimize the code for full compatibility with the Zynq Zed Board, ensuring smooth integration and operation. I can share examples of similar FPGA development work and outline a clear timeline for delivering your requested functionality. Then I will wait. Thanks.
