Abstract
A test system for testing communications over a bus connecting electronic devices, e.g., components of a computer system is preferably embedded in the devices themselves rather than in apparatus external to them, and is responsive to digital control signals, e.g., conforming to JTAG, for scanning test data into and out of the devices. The test system has a stress injection module for injecting a set of stimulus patterns on the bus; an error identification module for identifying an error resulting from the set of stimulus patterns; a bus tuning module for adjusting one or more bus operating and signaling parameters so that testing can be performed at one or more of a number of different sets of operating and signaling parameters; a programmable control module for controlling the bus tuning module; and a presentation module for presenting a plurality of results of the testing.
