Foundation series software packages.
Description
The XC1700D Hi-rel family of serial configuration PROMs
(SPROMs) provides an easy-to-use, cost-effective method
for storing Xilinx FPGA configuration bitstreams.
When the FPGA is in Master Serial mode, it generates a
configuration clock that drives the SPROM. A short access
time after the rising clock edge, data appears on the
SPROM DATA output pin that is connected to the FPGA
DIN pin. The FPGA generates the appropriate number of
clock pulses to complete the configuration. Once config-
ured, it disables the SPROM. When the FPGA is in Slave
Serial mode, the SPROM and the FPGA must both be
clocked by an incoming signal.
Multiple devices can be concatenated by using the CEO
output to drive the CE input of the following device. The
clock inputs and the DATA outputs of all SPROMs in this
chain are interconnected. All devices are compatible and
can be cascaded with other members of the family.
For device programming, either the Xilinx Alliance or the
Foundation series development systems compiles the
FPGA design file into a standard HEX format which is then
transferred to most commercial PROM programmers.
