What kind of jtag is the best

The installed circuit board generates a timing pulse which is fired at the CPU chip. If this timing pulse hits the CPU at exactly the correct time and frequency, then this makes the CPU boot the console in unprotected mode and therefore allow the booting of unofficial software.

The first way, connection testing see next section gives good test coverage, particularly for short circuit faults. Where two JTAG enabled pins are meant to be connected the test will make sure one pin can be controlled by the other.

Where enabled pins are not meant to be connected they are tested for short circuit faults by driving one pin and checking that these values are not read on the other pins. XJTAG will automatically generate the vectors required to run a connection test based on the netlist of a board and JTAG information for the enabled devices. In order to add this open circuit coverage it is necessary to communicate with the peripheral device from boundary scan on the enabled device.

If communication can be verified, there cannot be an open circuit fault. This type of testing can be very simple, for example lighting an LED and asking an operator to verify it has activated, or more complex, for example writing data into the memory array of a RAM and reading it back. The library files contain models for all types of non-JTAG devices from simple resistors and buffers to complex memory devices such as DDR3.

Because boundary scan disconnects the control of the pins on JTAG devices from their functionality the same model can be used irrespective of the JTAG device controlling a peripheral.

Most boards already contain JTAG headers for programming or debug so there are no extra design requirements.
