Patent ID: 6988232

Claim:
A system for accessing one or more electronic circuits for testing, debugging, or programmably configuring the electronic circuits, comprising: a test bus; a first test resource connected to the test bus; and a plurality of controllers connected to the test bus, each controller being coupleable to a respective electronic circuit to be accessed, wherein the first test resource is configured to send at least one first signal over the test bus to respective controllers to access, substantially in parallel, the electronic circuits via the respective controllers, wherein each controller is configured to employ a first protocol to access the respective electronic circuit coupleable thereto based on the at least one first signal sent over the test bus by the first test resource, and wherein the first test resource is further configured to send at least one expected-data signal to the respective controllers, the expected-data signal being indicative of data expected to be received from the electronic circuits as a result of being accessed by the respective controllers.
