1.6.5. Disabling I/O Pad Insertion

The Precision Synthesis software assigns I/O pad atoms (device primitives used to represent the I/O pins and I/O registers) to all ports in the top-level of a design by default. In certain situations, you might not want the software to add I/O pads to all I/O pins in the design. The Intel® Quartus® Prime software can compile a design without I/O pads; however, including I/O pads provides the Precision Synthesis software with more information about the top-level pins in the design.
