The following example programs demonstrate valid initialization and use of the runtime drivers. These are provided for reference purposes only, the build system provided with the drivers does not compile this program into an executable. The programs have no interface to an FPGA and instead use a set of stub functions for register access. To run this program, refer to the Building section of this chapter on compiling the drivers for their platform and the Porting to Platform section of this chapter for details on how to connect the drivers to their platform’s register access functions.
