ID:14084 WYSIWYG MCELL primitive "<name>" has illegal combination of mode parameters -- cannot be in XOR or XNOR mode, TFF mode, and parallel expander mode

CAUSE: The specified WYSIWYG MCELL primitive is in either XOR or XNOR mode (that is, the OPERATION_MODE parameter is set to XOR or XNOR) and is also in TFF mode (that is, the REGISTER_MODE parameter is set to TFF) and parallel expander mode (that is, the PEXP_MODE parameter is set to ON). The TFF mode can be used only when the OPERATION_MODE parameter is set to NORMAL, INVERT, or VCC.
