Examples — Dedicated examples are included for testing the HDL interface functionality
To test the HDL interface functionality, dedicated examples are included in the downloaded archive file. To open the examples, navigate to the corresponding folder. Note that the examples only test I/O channels for which the loopback test method is possible. The terminal board provided must be wired as described. Examples do not test I/O channels that require external hardware (for some examples a function generator or an oscilloscope is required), but running this example will still provide sufficient confirmation of the correct setup of this implementation. The examples only test interface channels which are provided by the base functionality of the I/O module. Please note that the examples provided have been color coded. The green colored subsystem (FPGA domain) is the part of the model which is actually compiled using HDL Coder and ultimately runs on the FPGA. The FPGA domain usually has a sample frequency in the range of 100 MHz and is set in the HDL Workflow Advisor (FPGA Synthesis Software Settings). The blue blocks (CPU domain) which surround the green subsystem are interfaces to the processor section of the model. The CPU domain usually has a sample frequency in the range of 1 kHz. The interrupt subsystem has been given another color (magenta), as its functionality is asynchronous to both the processor and FPGA. The interrupt source can be selected in the generated model in the Interrupt Setup block once the model has been run through the HDL Coder Workflow Advisor.
