NXP authors extend one UVM environment across the digital and analog sides of an automotive Ethernet PHY

An NXP-authored paper reports verifying an IEEE 802.3bw 100BASE-T1 PHY with one UVM environment extended to handle its analog interface. The environment adds analog source and probe components, error injection, and analog-domain coverage while retaining the digital UVM register-model environment; the authors demonstrate the approach on a released automotive Ethernet PHY.
