Two errors: Port "devoe" does not exist | WYSIWYG LCELL COMB primitive

Hi all, I encountered two errors when running quartus ii. I am using modelsim altera edition.

Here is what I did:

Take a verilog file as input, run quartus ii on it and get the verilog output file (.vo) file. I made some changes in .vo file and re-ran quartus two on it. I first changed the extension from .vo to .v, took the stratixiii_atoms.v (from modelsim_altera) as the lib file (use `include). But the quartus ii got two kinds of weired errors when running.

Error one: Port "devoe" does not exist in primitive "stratixiii_io_obuf" of instance "xxx"

Error two: WYSIWYG LCELL COMB primitive "xxx" must use LUT_MASK parameter

In the .v (changed from .vo), the instantiation of stratixiii_io_obuf does have the devoe port as .devoe(devoe). And "defparam xxxxxx.lut_mask = 64'h00FF00FF08F708F7" also presents in the file.

Does anyone has any idea why these things are happening?

Thanks in advance.
