Constraint File Reference

FPGA designs are captured in the Altium Designer design environment as schematic/OpenBus System/HDL documents. Implementation information, such as device pin allocations and pin electrical properties are not stored in these source files, they are stored in separate constraint files. One or more constraint files can be mapped to an FPGA project by adding them to a project Configuration.
