Abstract
A method is provided for securely configuring an FPGA with macros. Specifically, if an end user desires to use a macro from a macro vendor, the end user creates a marked design file containing a macro marker rather than the actual macro. The marked design file is converted into configuration data by a macro manager. Specifically, the macro manager obtains the macro from the macro vendor and replaces the macro marker with the macro prior to converting the design file into configuration data. The macro manager provides the configuration data to the end user. Because only the macro manager has access to the macro, the possibility of unlicensed use of the macro is diminished.
