INTEGRATED CIRCUIT WITH INPUT AND/OR OUTPUT BOLTON PADS WITH INTEGRATED LOGIC.

摘要

An input and/or output pad (P) is dedicated to an integrated circuit comprising a core with input and/or output pins. This pad (P) comprises a pad cell (PC) comprising a pad block (PB) connected to an input buffer (IB1, IB2) and/or an output buffer (OB) and arranged to be connected to one of the core input and/or output pins. The pad (P) also comprises a pad logic module (PLM) comprising a first boundary scan cell (BC1) and/or a second boundary scan cell (BC2), connected to the pad block (PB) through the input buffer (IB1, IB2) and/or output buffer (OB) and arranged to feed input signals to and/or deliver output signals from the pad block (PB), and control means connected to the first (BC1) and/or second (BC2) boundary scan cell(s) and adapted to receive control signals for controlling access to the first and/or second boundary scan cell(s) and feeding the first boundary scan cell (BC1) with the input signals and/or outputting the output signals delivered by the first boundary scan cell (BC 1).
