ABSTRACT:
An array of circuitry forming row and column ring oscillators is provided to determine aberrant gates in an integrated circuit. Control logic is coupled to the rows and columns to enable a ring oscillator of either a row or a column to oscillate. Based on outputs of these oscillations, aberrant gates in an integrated circuit may be more readily studied.
