Hermes API
Python Library for PCIe Gen6 EDSFF Redriver Control
The Hermes API delivers full programmatic access to Serial Cables' PCIe Gen6 EDSFF Redriver cards, bringing signal integrity tuning into your automated workflows.
Key Capabilities:
- Signal Tuning — Adjust equalization (2.3–20.8 dB), flat gain, and output swing across all redriver channels
- EDSFF Control — Manage PERST#, dual-port mode, power disable, and host LED signals
- Diagnostics — Monitor card temperature, fan speed, and current draw in real-time
- I²C/SMBus Access — Direct communication with downstream EDSFF devices
- Configuration Management — Save optimized settings to flash for persistent deployment
- Extensible with QuarchPy — For Quarch Mezzanine enabled cards (optional), this API can be used alongside to offer monitoring/tuning AND power/sideband measurements
Supports both x8 and x16 card variants. Integrates seamlessly with Atlas3 switch and Hydra JBOF APIs for end-to-end PCIe Gen6 test automation.
To Install:
pip install serialcables-hermes
