Configuration Through the Boundary Scan
Pins
Spartan/XL devices can be configured through the bound-
ary scan pins. The basic procedure is as follows:
•
•
DS060 (v1.8) June 26, 2008
Product Specification
Power up the FPGA with INIT held Low (or drive the
PROGRAM pin Low for more than 300 ns followed by a
High while holding INIT Low). Holding INIT Low allows
enough time to issue the CONFIG command to the
FPGA. The pin can be used as I/O after configuration if
a resistor is used to hold INIT Low.
Issue the CONFIG command to the TMS input.

The user must account for all TCK clock cycles after INIT
goes High, as all of these cycles affect the Length Count
compare.
For more detailed information, refer to the Xilinx application
note, "Boundary Scan in FPGA Devices." This application
note applies to Spartan and Spartan-XL devices.
