Abstract:
An internal net of a digital circuit is virtually probed while performing a dynamic functional stimulation that includes changing vectors asserted to a dynamic functional interface. A JTAG SAMPLE command is triggered through a JTAG interface at a timing during the dynamic functional stimulation by controlling the timing of a JTAG TCK rising clock edge. Captured JTAG SAMPLE data is shifted out to the JTAG interface. The JTAG SAMPLE data, which includes the logic states of internal nets at a chosen timing during the dynamic functional stimulation, are stored. A sequence database is built by repeating the test with incrementally different JTAG rising clock edge timings.

Claim (Index 1):
A digital circuit electronic system comprising:\n a unit under test that includes a digital circuit with at least one JTAG device in communication with a JTAG interface, and including a dynamic functional interface, and the JTAG device includes a plurality of pins; at least one piece of electronic equipment in communication with the JTAG interface and the dynamic functional interface; wherein the at least one piece of electronic equipment has a JTAG algorithm configured to emulate a JTAG controller, a dynamic functional stimulus algorithm, a synchronizing algorithm and a virtual probe data algorithm; wherein the dynamic functional stimulus algorithm is configured to communicate a plurality of vectors to the dynamic functional interface, and the plurality of vectors change during a dynamic functional stimulation; wherein the synchronizing algorithm is configured to trigger a JTAG SAMPLE command from the JTAG controller to the JTAG interface at a predetermined timing during the dynamic functional stimulation by controlling a timing of a JTAG TCK rising clock edge, and JTAG SAMPLE data is captured responsive to the JTAG SAMPLE command; and wherein the virtual probe data algorithm is configured to shift out the captured JTAG SAMPLE data to the JTAG interface and store the JTAG SAMPLE data, which includes logic states of the pins at the predetermined timing during the dynamic functional stimulation.
