ABSTRACT:
An analog signal monitoring (ASM) circuit (40, 42) non-intrusively monitors an analog circuit (20) within an electronic system. The ASM circuit (40,42) comprises input circuitry (80) that receives a plurality of analog signal inputs while the analog circuit (20) operates in a functional mode. Translation circuitry (142) associates with the input circuitry (80) for converting the analog signal inputs into digital signal representations of the analog signal inputs. Output circuitry (58) associates with the translation circuitry to output the digital representations. Control circuitry (114) controls the translation and output circuitry while the analog circuit (20) is in a functional mode. The ASM circuit (40, 42) also include an event qualification circuit (68) that includes input circuitry (236) to receive the digital signal representations, compare circuitry (104) to compare the received digital representations to an expected value and output a matched signal when a compared condition is identified.
