摘要
Embodiments of the present disclosure relate to detecting undervoltage conditions at a subcircuit. A power supply current of a first subcircuit is determined over a first number of previous clock cycles. A cross current flowing between the first subcircuit and a second subcircuit is determined over the first number of previous clock cycles. An estimated momentary supply voltage present at the first subcircuit is then determined based on the power supply current of the first subcircuit over the first number of previous clock cycles and the cross current flowing between the first subcircuit and the second subcircuit over the first number of previous clock cycles.
