Creating GTL with High Level Synthesis

Usage

$ git clone https://github.com/herbberg/hls4gtl.git
$ git checkout <branch/tag>
$ python manage.py init </path/to/menu/dist> <module_id>
$ python manage.py export

The generated symlink current_dist in the project root directory is the entry point for the auto generated HLS source files implementing a menu module. The symlink can be configured either manually, by external scripts or by using manage.py which provides also integrity checks on the linked distribution directory:

$ python manage.py init|status|reset [...]

To generate a solution, run simulation or export the IP core use the HLS specific comamnds:

$ python manage.py csim|csynth|cosim|export|clean [...]

C/Co simulation

Running manage.py csim or manage.py csim automatically crawls for test vector files in the menu distribution's testvectors directory. The search pattern is TestVector*.txt. Every located test vector is loaded by the C/Co simulation.

To run the C simulation with one or more custom test vectors apply them using the --testvector <file ...> option.

$ python manage.py csim --testvector custom_testvector.txt

HLS directives

Additional HlS directives can be added in config/directives.tcl

Menu distributions

Use tm-distribute to create a distribution from an XML trigger menu.
