Methods and system for sensing dynamic failures in an electronic circuit. An exemplary system includes a drive source, a radiant energy source, and a signal comparator. The drive source supplies a dynamic input signal to the electronic circuit, thereby causing the electronic circuit to output a signal. The radiant energy source generates and directs radiant energy at the electronic circuit and thus induces localized changes in the output signal of the electronic circuit. The signal comparator compares the output signal to an expected output signal, thereby producing a comparison signal proportional to the match between the input and output signals. A data processing device generates an image based on the comparison signal and an image based on a reflection signal. A display device displays at least a portion of the generated images simultaneously.
