Integrating a Processor with Custom Logic
As shown in the following figure, you can click on the Launch Xilinx SDK button on the
Software tab of a Hardware Co-Simulation block GUI to launch the Xilinx SDK.
When Xilinx SDK is launched from System Generator, the following items are
automatically set up by System Generator.
1. The workspace is set to the one as specified on the above Hardware Co-Simulation
block GUI.
2. A Xilinx Hardware Platform Specification is automatically created and points to
<netlist_dir>/SDK_Export/hw/<edk_project_name>.xml. This XML file is
generated by XPS through the Export to SDK utility. It contains information from the
hardware specification MHS file and software specification MSS file in the original
XPS project.
3. System Generator automatically adds
<netlist_dir>/SDK_Export/sysgen_repos to
local software repositories. You can verify this by going to Xilinx Tools > Repositories
> Local Repositories as shown in the following figure. By doing so, Xilinx SDK can
locate the software driver generated by System Generator.
