摘要： A circuit includes a memory (130) coupled to an analog line coverage circuit (104). The analog line coverage circuit includes a plurality of buffers (151-154) in which each buffer is coupled to one memory location of the memory, a plurality of bin cells (161-164) in which each bin cell is coupled to a buffer, a multiplexer (170), each input terminal of which is coupled to a bin cell, and an analog-to-digital converter (180) coupled to the multiplexer and to an output terminal of the analog line coverage circuit. The analog line coverage circuit stores an analog voltage that is representative of a number of occasions that a memory location is accessed, and outputs a signal indicative thereof. A processor (102) is coupled to the memory and to the analog line coverage circuit, and the processor enables the analog line coverage circuit when the processor is in a debug mode.

摘要： An output driver circuit having an input stage and an output stage, wherein the output stage and the input stage are configured to function as (1) a low-frequency voltage follower and (2) a high-frequency feedback loop for the output driver circuit. In operation, the low-frequency follower and the high-frequency feedback loop may precisely regulate the output voltage of the output driver circuit when large load transients occur. A compact charge pump may be used to supply additional voltage required to operate a current mirror of the output driver circuit.
