Functional Description
Readback
FPGA configuration data can be read back using either the
Slave Parallel or JTAG mode. This function is disabled if the
Bitstream Generator
or Level2.
Along with the configuration data, it is possible to read back
the contents of all registers and distributed RAM.
To synchronously control when register values are captured
for readback, use the CAPTURE_SPARTAN3 library primi-
tive, which applies for both Spartan-3 and Spartan-3E
FPGA families.
The Readback feature is available in most Spartan-3E
FPGA product options, as indicated in
back feature is not available in the XC3S1200E and
XC3S1600E FPGAs when using the -4 speed grade in the
Commercial temperature grade. Similarly, block RAM Read-
back support is not available in the -4 speed grade, Com-
mercial temperature devices. If Readback is required in an
XC3S1200E or XC3S1600E FPGA, or if block RAM Read-
back is required on any Spartan-3E FPGA, upgrade to
either the Industrial temperature grade version or the -5
speed grade.

The Xilinx iMPACT programming software uses the Read-
back feature for its optional Verify and Readback opera-
tions. The Xilinx ChipScope™ software presently does not
use Readback but may in future updates.
