Error: PRL13: Insufficient voltage resources (VCCI, VCCR)=(<voltage value>v, <voltage value>v) for RCLK. This design requires <number of I/Os required>, Total available: <number of I/Os available>. Please verify that sufficient VCCR has been assigned for your design.

The I/O technology for an RCLK macro in your design is not compatible with the I/O bank VCCI and VCCR (VREF) settings. RCLK macros can only be assigned to the RCLK I/O Banks (Bank 4 and Bank 5). The I/O technology for an RCLK macro must match the VCCI and VCCR settings for the I/O bank that contains the macro.

Action

Modify the VCCI and VREF settings for your RCLK I/O bank to be compatible with the RCLK macro settings. To modify the RCLK IO Bank Settings, use PinEditor (or a PDC file).
