Description
CFG_DATA[6]
Output
For Slave-Serial configuration mode, CFG_DATA[6] is the serial data signal for
Serial-Slave Chain 6 and is connected to DIN of the first FPGA in the
Slave-Serial Chain 6. For Slave-SelectMAP configuration mode, CFG_DATA[6]
is the data bit 6 on the SelectMAP bus and is connected to D6 on all target
FPGAs.
CFG_DATA[7]
Output
For Slave-Serial configuration mode, CFG_DATA[7] is the serial data signal for
Serial-Slave Chain 7 and is connected to DIN of the first FPGA in the
Slave-Serial Chain 7. For Slave-SelectMAP configuration mode, CFG_DATA[7]
is the data bit 7 on the SelectMAP bus and is connected to D7 on all target
FPGAs.
CFG_MODE[0]
Output
The CFG_MODE pins set the configuration mode on the target FPGAs.
Connect CFG_MODE[0] to the M0 pin on all target FPGAs.
CFG_MODE[1]
Output
The CFG_MODE pins set the configuration mode on the target FPGAs.
Connect CFG_MODE[1] to the M1 pin on all target FPGAs.
CFG_MODE[2]
Output
The CFG_MODE pins set the configuration mode on the target FPGAs.
Connect CFG_MODE[2] to the M2 pin on all target FPGAs.
CFG_CCLK
Output
CFG_CCLK is the configuration clock source for the target FPGAs. The
CFG_CCLK is derived from the SYSCLK. The CFG_CCLK frequency is half
the SYSCLK frequency. Connect CFG_CCLK to the CCLK pin on all target
FPGAs.
CFG_PROG
Output
CFG_PROG is pulsed Low at the beginning of the configuration download to
reset the configuration state of the target FPGAs. CFG_PROG is connected to
the PROG_B pin on all target FPGAs.
CFG_INIT
Input
Target FPGA INIT monitor pin. At the start of the configuration process, the
System ACE MPM controller waits for INIT to go High before initiating delivery
of configuration data through the CFG_DATA pins. CFG_INIT is connected to
the INIT pin on all target FPGAs.
CFG_BUSY
Input
When CFG_BUSY is High, the CFG_DATA outputs are held. If the target FPGA
configuration mode is Slave-SelectMAP and if the CFG_CCLK is greater than
50 MHz, connect the CFG_BUSY pin to the BUSY pin on all target FPGAs.
Otherwise, pull-down the CFG_BUSY pin to GND.
CFG_DONE
Input
CFG_DONE monitors the DONE status on all target FPGAs. Connect the
CFG_DONE to the DONE pin on all target FPGAs. DONE must be pulled High
with an external 330-
8
pull-up resistor. The BitGen option DriveDONE should
be left in the default
“
NO
”
setting when generating bitstreams for Xilinx FPGAs.
CFG_WRITE
Output
Slave-SelectMAP write-enable pin. Connect the CFG_WRITE pin to the
RDWR_B pin on all target FPGAs.
CFG_CS[0]
Output
Slave-SelectMAP chip-enable for target FPGA 0. Connect the CFG_CS[0] pin
to the CS_B pin on target FPGA 0.
CFG_CS[1]
Output
Slave-SelectMAP chip-enable for target FPGA 1. Connect the CFG_CS[1] pin
to the CS_B pin on target FPGA 1.
CFG_CS[2]
Output
Slave-SelectMAP chip-enable for target FPGA 2. Connect the CFG_CS[2] pin
to the CS_B pin on target FPGA 2.
CFG_CS[3]
Output
Slave-SelectMAP chip-enable for target FPGA 3. Connect the CFG_CS[3] pin
to the CS_B pin on target FPGA 3.
