ID:169203 PCI-clamp diode is not supported in this mode. The following <number> pins must meet the Altera requirements for 3.3V, 3.0V, and 2.5V interfaces if they are connected to devices other than the supported configuration devices. In these cases, Altera recommends termination method as specified in the Application Note 447.

CAUSE: You assigned the specified configuration pins in your design to 3.3-V, 3.0-V, or 2.5-V interfaces. However, your assignment do not meet the Altera requirements for 3.3V, 3.0V and 2.5V interfaces.

ACTION: Refer to the Application Note 447, which describes issues related to 3.3-V, 3.0-V, or 2.5-V interfaces.
