- The data type at port must be scalar.
- The data type at port must be either fixed point or Boolean.
- xlType doesn't allow negative value for binary point.
- xlType doesn't allow binary point position greater than word-size.
HDL Coder error when converting m-code to System Generator Black Box

Everything went fine from fixed-point conversion until post code generation tasks where the console shows following errors:
### Begin Verilog Code Generation ### Working on PLL_HDL_CODER_FixPt as PLL_HDL_CODER_FixPt.v ### Generating Resource Utilization Report resource_report.html Error occurred when running post codegeneration tasks Error: failed to run post code generation tasks: MATLAB:builtins:BadDataType In 'hdlcoder:matlabhdlcoder:porttypeforXSG', data type supplied is incorrect for parameter {2}.
I guess Xilinx System Generator doesn't accept data type provided by HDL Coder. And by the way, where is parameter {2}? To be honest, Matlab console and error tracing are rather ambiguous to me.
PS: Sorry for duplicating this question (the other one is in Newsgroup). However, I believe that this is where I will got the appropriate answer.

The message is indeed vague and will be improved.
HDL Coder can't turn a MATLAB design into a System Generator blackbox, because at least one port is of data type that doesn't meet the following requirements:
