Error when generating test bench

I am generating a test bench for an AES encrypt/decrypt function that I wrote. It has the prototype of

function EnPlainText = aes_init(cipherPlain,key,mode)

%EnPlainText - Encrypted/Plain Text
%CipherPlain - Cipher/plain text
%key         - key
%mode        - true for encryption and false for decrypt

I created a testbench by the name 'main.m' with the following contents:

cipherText = aes_init(16:-1:1,1:16,true)
plainText  = aes_init(cipherText,1:16,false)

I then converted the code into HDL code using the HDL converter. All the steps until the HDL verification was successful without any warnings or errors. When I try to test the generated code with test bench using Verify with HDL Test Bench option in the HDL coder menu, the following error is shown.

### Begin TestBench generation.
Error using eml_error (line 20)
BIT must be integers between 1 and 4 for embedded.fi.

Why is this error being shown. How can I fix this?

Thanks.

bro i too get same error, did u figure it out. can u tell me what to do to fix that error

Need dut.m and testbench.m and a project file (with data type settings, HDL settings) to debug such floating point to fixed poitn conversion or HDL code generation issues.
