Abstract
A method is provided for watermarking FPGA configuration data. Specifically, if an end user desires to use a macro from a macro vendor, the end user creates a design file containing a marked macro received from the macro vendor, rather than the actual macro. The end user then uses an FPGA programming tool to convert the design file into configuration data. Specifically, the FPGA programming tool processes the design file to detect marked macros. If a marked macro is detected, the FPGA programming tool embeds a watermark corresponding to the macro within the configuration data.
