HIGH-SPEED FUNCTIONAL PROTOCOL BASED TEST AND DEBUG

An integrated circuit (IC) device and a method for communicating test data utilizes test control circuitry, and a test controller. The test controller is coupled with the test control circuitry and decodes packetized test pattern data to identify configuration data for the test controller and test data for the test control circuitry. The test controller further communicates the test data to the test control circuitry, and packetizes resulting data received from the test control circuitry. The resulting data corresponds to errors identified by a test performed based on the test pattern data.

TECHNIQUES FOR ISOLATING INTERFACES WHILE TESTING SEMICONDUCTOR DEVICES

Techniques for isolating interfaces while testing a semiconductor device include a semiconductor device having a link interface that couples the semiconductor device to a high-speed data transfer link, a clock control unit that transmits one or more clock signals to the link interface; and a protection module. The protection module asserts a clock stop request to the clock control unit and, in response to receiving a clock stop acknowledgement from the clock control unit, asserts a clamp enable to cause the link interface to be isolated from portions of the semiconductor device. After waiting for a first predetermined period of time to expire, the protection module de-asserts the clock stop request.
