Quartus II I/O bank voltage settings

Running into a problem when allowing quartus to set I/O bank voltage. Particularlly 1.8V

The tool generates the following in the .qsf

set_instance_assignment -name IO_STANDARD "1.8 V" -to ramAddrPout[10]

however when compiling I get the following error:

Error: Error reading Quartus II Settings File location, line# ##

Info: set_instance_assignment -name "IO_STANDARD" 1.8 V -to "ramAddrPout[10]"

But stickler is when reading the documentation they refer to all voltage IO as "voltage_value-V"

When I manually edit the .qsf to the following everything compiles fine. Is there a bug in the quartus tool. I don't understand why the tool generated .qsf isn't working until I edit "1.8-V" or "1.8V"

set_instance_assignment -name IO_STANDARD "1.8-V" -to ramAddrPout[10]

or

set_instance_assignment -name IO_STANDARD "1.8V" -to ramAddrPout[10]

Regards,

D

    I tried a Cyclone III test case in Quartus II version 7.2 SP3. The .qsf had "1.8 V" with a space, but Quartus did not give an error. The problem might be specific to your device family, but I suspect it is a bug that has already been fixed if you are using an older Quartus version.

    It might, but I doubt it. I expect that the Web Edition and Subscription Edition use the same code for features available in both.

    If you are using QII 7.2 SP2 or SP3, I suggest that you file a service request. If you are using an older version, I suggest that you try the latest version.
