u1: STRTUP port map (UCLK =><clock name>);
INBUF
The I/O INBUF option will disable all unused input buffers to save power. INBUF mode limits some of the function-
ality of Boundary Scan. For Boundary Scan testing it is recommended that the I/O Power Save mode be set to ON
so that all of the I/Os will be fully functional.
