Submodules

hls4ml.backends.quartus.quartus_backend module

class hls4ml.backends.quartus.quartus_backend.QuartusBackend

Bases: FPGABackend

build(model, synth=True, fpgasynth=False, log_level=1, cont_if_large_area=False)

Builds the project using Intel HLS compiler.

Parameters:

• model (ModelGraph) – The model to build

• synth – Whether to run HLS synthesis

• optional – Whether to run HLS synthesis

• fpgasynth – Whether to run FPGA synthesis (Quartus Compile)

• optional – Whether to run FPGA synthesis (Quartus Compile)

• log_level – Logging level to be displayed during HLS synthesis (0, 1, 2)

• optional – Logging level to be displayed during HLS synthesis (0, 1, 2)

• cont_if_large_area – Instruct the HLS compiler to continue synthesis if the estimated resource usage exceeds device resources

Errors raise exceptions

create_initial_config(part='Arria10', clock_period=5, io_type='io_parallel', **_)

Create the minimal conversion config for the backend.

Subclasses should implement this method to provide the initial configuration for the conversion.

get_default_flow()

The name of the default flow of the backend.

Default flow is used as the conversion target if the target flow has not been specified.
