Abstract

The invention relates to an electronic system comprising a plurality of circuit lines and an error detection component for detecting errors on and between the plurality of circuit lines, wherein each circuit line having a voltage different to ground level, the error detection component being adapted to perform a test routine comprising the steps of: —selecting one circuit line out of the plurality of circuit lines; —determining the voltage of the selected circuit line and storing the voltage value; —discharging the selected circuit line to ground level; —iteratively repeating the aforementioned steps of selecting a circuit line, determining and storing its voltage and discharging for further circuit lines; —comparing the stored voltage values associated with the respective circuit lines with a threshold value; and —generating an error indicator if at least one stored voltage value is below the threshold value.
