| CAUSE: | You turned on the specified logic options either globally or on specific nodes in the design in a previous version of the Quartus II software. However, the logic options are not supported by this version of the Quartus II software. Therefore, the assignments are ignored by the Compiler. |
| ACTION: | Turn off the options by using the cmp add_assignment Tcl command or by manually editing the assignment files for the project. To achieve the same results as the unsupported logic options, turn on Optimize I/O cell register placement for timing. |
