- EthSwt Hardware Architecture — Switch Chip Design for Software Engineers
The three hardware variants for switch/PHY arrangements defined by the AUTOSAR SWS, the forwarding engine, and typical switch chips in practice.
- EthSwt Hardware Deep Dive — Port Interfaces and Signal Processing at the PCB Level
Host-side interfaces (RGMII/SGMII) to the switch, internal forwarding paths, PCB and power aspects of multi-port chips, and the path a frame takes through the switch.
- EthTrcv from the Hardware Side — PHY Architecture for Software Developers
What actually happens inside the PHY chip when EthTrcv_Init is called: the PMA/PCS/MDI architecture, link training on 100BASE-T1, and PHY-level power states — explained conceptually, without the electronics deep dive.
- EthTrcv Hardware Deep Dive — The Physical Interfaces of the PHY Chip
A hardware deep dive for software developers: what happens at PCB level when EthTrcv is configured — MAC interfaces, MDIO bus, line side, and the path of a frame through the PHY.
- EthSwt — Internal Switch Fabric Architecture for Software Engineers
What's actually inside a switch chip's silicon? Shared-memory vs. crossbar fabric, the lookup engine, buffer architecture, egress queues in hardware, and the embedded management core.
