Hello there,
Hello,
I'm converting Matlab file(.m) to HDL code. The fixed-point file is working 100% , but I got the following errors when I tried to convert it to VHDL code. I found that I have to use the VHDL math library to get those errors fixed.
Can you please help me to run the VHDL code at Matlab
_ _ *.m file orders _ _ *
Y= Sin(x);
Y= Cos (x);
Power(a,b);
round (a,b);
Y=abs(x);
_ VHDL errors _ *

The short answer is that the function calls you list are not supported by HDL Coder, just like the message you received says. The list of supported functions are available in the documentation at:
You can build a custom lookup table to implement any function, given the appropriate input range and desired output granularity. See the documentation on lookup table replacement.
