    摘要: A system and method for communicating with contactless IC cards of multiple protocols includes transmitting an IC card polling signal and receiving a data transmission from an IC card. A processor is configured to determine whether or not a data transmission is received in response to the polling signal. The processor is configured to decode the data transmission in real-time if it is received in response to the polling signal. The processor is otherwise configured to first store the received data transmission in a memory and then decode the stored data transmission.

    摘要: Techniques and mechanisms for evaluating I/O buffer circuits. In an embodiment, test rounds are performed for a device including the I/O buffer circuits, each of the test rounds comprising a respective loop-back test for each of the I/O buffer circuits. Each of the test rounds corresponds to a different respective delay between a transmit clock signal and a receive clock signal. In another embodiment, a first test round indicates a failure condition for at least one I/O buffer circuit and a second test round indicates the failure condition for each of the I/O buffer circuits. Evaluation of the I/O buffer circuits determines whether the device satisfies a test condition, where the determining is based on a difference between the delay corresponding to the first test round and the delay corresponding to the second test round.

    摘要: A system and method for communicating with contactless IC cards of multiple protocols and power levels includes generating a first alternating magnetic field with an interrogator for energizing a proximate IC card and receiving a data transmission from the IC card. A processor of the interrogator is configured to decode the received data transmission. The interrogator then generates a second alternating magnetic field having a different magnetic field strength than the first alternating magnetic field when failing to decode the data transmission being received from the IC card. The processor then attempts to decode a data transmission received from the IC card in response to the second alternating magnetic field.

    摘要: An output-relative signal receiver to test an integrated circuit that provides an output-relative data signal. The output-relative signal receiver receives the output-relative data signal and a corresponding output strobe signal from an integrated circuit device and produces a test strobe signal derived from the output strobe signal. The test strobe signal is used to test a feature of the integrated circuit device indicated by the output-relative data signal.

    摘要: A test interface mode over general purpose input/output peripheral connectors of a multichip package (MCP) or system in package (SIP) for an integrated device chip having a wide functional interface. The wide functional interface has more signals than there are available external connectors on the SIP package. Logic in the SIP package includes selection logic to select one or more portions of the wide functional interface to test in a given cycle. Logic in the SIP package multiplexes peripheral connectors as a test interface for the device chip, instead of dedicating connectors on the SIP package for a direct access test interface.
