Error: PRL15: Insufficient voltage resources (VCCI, VCCR)=(<required VCCI voltage value>v, <required VCCR voltage value>v) for HCLK. 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 HCLK macro in your design is not compatible with the I/O bank VCCI and VCCR (VREF) settings. HCLK macros can only be assigned to the HCLK I/O Banks (Bank 0 and Bank 1). The I/O technology for an HCLK 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 HCLK I/O bank to be compatible with the HCLK macro settings. To modify the HCLK I/O Bank Settings, use PinEditor in MultiView Navigator (or a PDC file).
