Abstract: A method for designing an integrated circuit having analog and digital circuit portions is disclosed. The method involves providing an emulation circuit, which preferably comprises a number of gates equivalent to a number of gates in the digital circuit portion, affixing the emulation circuit on a test substrate together with a version of the analog circuit portion having at least some of the defined functions of the analog circuit portion, and then testing the analog circuit version.

Abstract: An electronic component for failure detection and analysis of bus activity comprises configuration circuitry, a buffer, and read circuitry. The configuration circuitry, the buffer, the read circuitry and the bus being tracked are on the same die. The configuration circuitry identifies one or more modes, one or more triggers, and one or more responses associated with the triggers. The buffer stores transactions on a bus according to the configuration circuitry. The read circuitry reads data from the buffer. A method of tracking bus activity comprises configuring a bus activity tracking component; monitoring an interface for a trigger event; and performing associated responses upon the occurrence of the trigger event.
