Boundary-Scan Mode
In the boundary-scan mode, no non-dedicated pins are
required, configuration being done entirely through the
IEEE 1149.1 Test Access Port.
Configuration through the TAP uses the CFG_IN instruc-
tion. This instruction allows data input on TDI to be con-
verted into data packets for the internal configuration bus.
The following steps are required to configure the FPGA
through the boundary-scan port (when using TCK as a
start-up clock).
1.
Load the CFG_IN instruction into the boundary-scan
instruction register (IR)
2.
Enter the Shift-DR (SDR) state
3.
Shift a configuration bitstream into TDI
4.
Return to Run-Test-Idle (RTI)
5.
Load the JSTART instruction into IR
6.
Enter the SDR state
7.
8.
Clock TCK through the startup sequence
Return to RTI
Configuration and readback via the TAP is always available.
The boundary-scan mode is selected by a <101> or <001>
on the mode pins (M2, M1, M0).
Configuration Sequence
The configuration of Virtex-E devices is a three-phase pro-
cess. First, the configuration memory is cleared. Next, con-
figuration data is loaded into the memory, and finally, the
logic is activated by a start-up process.
Configuration is automatically initiated on power-up unless
it is delayed by the user, as described below. The configura-
tion process can also be initiated by asserting PROGRAM.
The end of the memory-clearing phase is signalled by INIT
going High, and the completion of the entire process is sig-
nalled by DONE going High.
The power-up timing of configuration signals is shown in
Figure 20
