Abstract
A JTAG testing system including a JTAG test equipment and a device under test compatible with the JTAG configured to form a synchronous data transmission connection with one another for transferring test data through a transmission path placed between predetermined interfaces. An asynchronous connection can be used as the transmission path between the interfaces, whereby the test equipment and said device under test are provided with a transceiver on the transmission path side configured to arrange the test data to be sent from said interface into a mode appropriate for an asynchronous transmission path and correspondingly to arrange the test data to be received from the asynchronous transmission path into a synchronous mode required by said interface.
Claims20
A JTAG testing system comprising a JTAG test equipment and a device under test compatible with the JTAG configured to form a synchronous data transmission connection with one another for transferring test data through an asynchronous transmission path between predetermined interfaces, wherein the test equipment and the device under test comprise a transceiver configured on the side of the transmission path, the transceiver being configured to arrange the test data to be sent from said interface into a mode appropriate for an asynchronous transmission path and correspondingly to arrange the test data arriving from the asynchronous transmission path to be received into a synchronous mode required by said interface.
A transceiver configured to the transmission path side of the JTAG test equipment, the transceiver being configured to arrange the test data to be sent from the interface according to the JTAG definition into a mode appropriate for an asynchronous transmission path and correspondingly to arrange the test data to be received from the asynchronous transmission path into a synchronized mode required by said interface.
