Creating Compilation Targets
5.
Create a new directory (e.g., Bitstream) under the plugins/compilation directory
of your System Generator software install tree. Copy the xltarget.m,
xltools_postgeneration.m, and xltools_target.m files into this directory.
Note: The System Generator Compilation submenus mirror the directory structure under the
plugins/compilation directory. When you create a new directory, or directory hierarchy, for the
compilation target files, the names of the directories define the taxonomy of the compilation target
submenus.
6.
Copy the xlBitstreamPostGeneration.m, xlToolsMakebit.pl,
balanced_xltools.opt and bitgen_xltools.opt files from the
examples/comp_targets directory into a directory that is in your MATLAB path.
These files must be in a common directory.
7.
In the MATLAB command window, type the following:
>> rehash toolboxcache
>> xlrehash_xltarget_cache
8.
You can now access the newly installed compilation target from the System Generator
graphical interface.
Using XFLOW
The post-generation scripting included with this example uses XFLOW to produce a
configuration file for your FPGA. XFLOW allows you to automate the process of design
synthesis, implementation, and simulation using a command line interface. XFLOW uses
command files to tell it which tools to run, and how they should be run.
This example contains two XFLOW options files, balanced_xltools.opt and
bitgen_xltools.opt. These files are associated with the implementation and
configuration flows of XFLOW, respectively. The balanced_xltools.opt options files
runs the Xilinx NGDBUILD, MAP, and PAR tools. The settings for each tool are specified in
the options files . The bitgen_xltools.opt file runs BITGEN to produce a
configuration file for your FPGA. You may modify these files as desired (e.g., to run the
timing analyzer after PAR).
