Apparatus and method for flexible visibility in integrated circuits with minimal package impact

摘要

An apparatus and method for flexible visibility in an integrated circuit are disclosed. As one example, an apparatus for flexible visibility in an integrated circuit is disclosed. The apparatus includes a switch unit disposed in the integrated circuit, the switch unit configured to receive a plurality of signals associated with a plurality of visibility points in the integrated circuit, and output the received plurality of signals in a serial form. Also, the apparatus includes a formatter unit disposed in the integrated circuit and coupled to the switch unit, the formatter unit configured to receive the plurality of signals in the serial form, and output a plurality of formatted signals including the received plurality of signals.
