3.1.2. JTAG and the FPGA

The tile contains configuration and debug JTAG chains.

The two JTAG chains are completely separate:

Both scan chains are available through separate signal groups on the HDRZ tile header. The configuration JTAG signals are prefixed C_, and the debug JTAG signals are prefixed D_. For example, C_TDI is the configuration JTAG test data in signal and D_TDO is the debug JTAG test data out signal. See Table A.3 for details of the available JTAG signals.
