Industrial MESBox Controller Design
Configure 100Ω Ethernet rules, route the Ethernet pairs first, then run full DRC.
Thought for 11 sec
I’ll configure the Ethernet nets for 100 Ω differential routing, route the Ethernet pairs first, then run a full DRC and report the remaining board issues.
Thought for 15 sec
I’m blocked because the account has no available ACUs, so I can’t configure routing rules, route traces, or run DRC right now.
Accomplished before this request:
- Ethernet schematic support was completed: RJ45 center taps, LEDs, ESD arrays, KSZ9477 straps/clock/reset/MDIO, and CM4 uplink.
- Ethernet block placement was completed: RJ45s on the board edge, ESD arrays behind them, KSZ9477 behind the protection row, and crystal/load caps near U61.
- Ethernet layout constraints were documented in the project file.
Remaining work when ACUs are available:
- Configure 100 Ω differential-pair rules for all Ethernet pairs.
- Route Ethernet pairs first from RJ45 → ESD → KSZ9477.
- Route remaining power/control nets.
- Run full DRC and fix/report remaining layout violations.
