Foundation Constraints
Foundation Series 2.1i User Guide
This appendix discusses some of the more common constraints you
can apply to your design to control the timing and layout of a Xilinx
FPGA or CPLD; it describes how to use constraints at each stage of
design processing.
This appendix contains the following sections.

For a complete listing of all supported constraints, refer to the
Libraries Guide (Chapter 12, “Attributes, Constraints, and Carry
Logic”). For a more complete discussion of how timing constraints
work in Foundation, refer to the Development System Reference Guide
(“Using Timing Constraints”). For information on all attributes,
including timing constraints, used in CPLD designs, refer to the
Foundation online help.
