You can change part of the board definition file for a Xilinx® FPGA board to customize it. For example, you want to change the default interface for the ML605 to MII. However, you cannot change the board definition file directly. Instead, make a copy of the file and then change the copied file.
Create a copy of the board definition file using the FPGA Board Manager. Follow these steps:
Start the FPGA Board Manager by typing the following at the MATLAB® command prompt:
In the FPGA Board List, select the board you want to copy and click Clone.
In the Create copy dialog box, specify the file name and location and click OK. Choose a new file name (and, optionally, a location) so that the original definition file is preserved.
Specify FPGA board information for the copy to customize it. By default, the copy inherits its information from the original, so you have to change only those fields that differ.
The copy of the original board now appears in the FPGA Board List. It also appears on the Board Name list in the FPGA-in-the-Loop Wizard and you can use the board with FIL simulation.
