1.2.13. Secure Device Manager (SDM) Pins
Note: Altera recommends that you create a Quartus® Prime design, enter your device I/O assignments, and compile the design. The Quartus® Prime software checks your pin connections according to I/O assignment and placement rules. The rules differ from one device to another based on device density, package, I/O assignments, voltage assignments, and other factors that are not fully described in this document or the device user guides.
