1. A method for determining a condition associated with an integrated circuit disposed on a circuit board, comprising:
- receiving electromagnetic-interference (EMI) signals from one or more antennas while the integrated circuit on the circuit board is operating, wherein the one or more antennas are disposed on the circuit board, and wherein the antennas receive EMI signals generated from the integrated circuit while the integrated circuit is operating; and
analyzing the received EMI signals to determine the condition, wherein the one or more antennas comprise at least two metal traces on the circuit board, wherein the at least two metal traces have different lengths, and wherein the different lengths correspond to a set of predetermined wavelengths that are determined based on an ability to accurately determine the condition.

Abstract
Embodiments of a system that determines a condition associated with an integrated circuit disposed on a circuit board are described. During operation, the system receives electromagnetic-interference (EMI) signals from one or more antennas while the integrated circuit is operating, where the one or more antennas are disposed on the circuit board. Then, the system analyzes the received EMI signals to determine the condition.
