Resumen
The article describes hardware and software tools to control a chip, which provides functions of the physical layer of the Ethernet protocol, in conditions of testing and debugging of the chip, including the cases of autonomous testing without an interconnection with data link layer equipment. In addition, tools for implementing other testing scenarios are discussed shortly, including BER measuring tool and auto-negotiation testing tool. Discussed tools were developed to support testing and debugging of an Ethernet transceiver chip which supports transmit speed of 10, 100 and 1000 Mbit/s (10BASE-T, 100BASE-TX and 1000BASE-T protocols
