Any idea why it is so difficult to get stable filter with fdatool from matlab?
I'm designing IIR BP filter for implementation in LatticeECP in audio domain, but I can't get decent signal out of the implemented filter. (very noisy signal)
If I'm simulating the design in matlab everything seems to be fine.
Are there some general guidelines tha

what is the difference between labview and vhdl
vhdl is programming language for hardware say FPGA/ASIC.
where as Labview is higher lever language to design complete system. Labview project may contain some block with vhdl code also. It can be compared with matlab for instance.

you can generate white noise with matlab, and then transform it binary data, such as symbol function.
you can store these data and regard it white noise.

Your question is a bit unclear. matlab mabe pluged into your vhdl simulator.
You can eother use some commertial library that generates vhdl out of matlab, or
use simulator and matlab C API to connect both.

Xilinx,Leonardo spectrum can generate schematics for vhdl code.
Even you can write the code in matlab and system generator will generate vhdl code for the written code.
from that you can generate schematics.

If your purpose is just generating vhdl code, matlab HDL Coder is suitable. However, it generates lots of files, and most of time result is not suitable for FPGA bitstream generation.
