Blocks for HDL Code generation

3 views (last 30 days)
What are the toolboxes in Simulink that can be used to generate HDL netlist?
What is the difference between DSP System Toolbox HDL Support, Embedded Coder, HDL Coder, HDL Verifier, Mixed Signal Blockset and Xilinx Toolbox (on installing System Generator)? Which of these blocks can be used to generate HDL netlist for target FPGA in Vivado?
I've gone through the document https://in.mathworks.com/help/hdlcoder/ug/using-xilinx-system-generator-for-dsp-with-hdl-coder.html , but I couldn't open the example file mentioned witht he following message: "Block diagram 'hdlcoder_slsysgen' is not loaded."
Please help!

If you type hdllib on at the MATLAB command line, the Simulink library browser will show you the list of blocks supported for HDL code generation. These are selective blocks in Simulink, DSP System Toolbox (called DSP System Toolbox HDL Support), etc. Type hdllib off to get the library browser to show all the Simulink blocks. You can generate HDL for these blocks and use the HDL to target Xilinx devices.
System Generator is an AMD-Xilinx product which allows you to target Xilinx devices using those blocks.

I don't think there is an easy or clear answer to this question. My suggestion would be to try all 3 workflows (HDL Coder, System Generator, both) to see which is more to your liking. I would start with a simple example that you can run through the entire workflow.
