Quartus

I/O standard <name> is not supported for selected device family


CAUSE: You manually edited the Compiler Settings File (.csf), and selected the specified default I/O standard for the current project, but the Quartus II software does not support the I/O standard for the selected device family.
ACTION: Change the I/O standard for the device family. Altera recommends using the Voltage tab of the Device & Pin Options dialog box to specify the I/O standard, rather than manually editing the CSF.
