Is there a way to send arguments to the simulator?

I'm using the Vitis backend. Is there a way to send arguments to the invocation of the simulator besides manually editing the run_xsim.sh file that is generated?

You can specify input_data_tb and output_data_tb as NumPy arrays or .dat files. See here for Keras:

hls4ml/hls4ml/converters/__init__.py

Line 181 in 2c17f66

input_data_tb=None,

. Analogous for PyTorch.

This is then picked up and forwarded to both CSim (software simulation) and CoSim (RTL simulation)

I was thinking about arguments to the xsim command itself, like how I added --maxdeltaid 100000 --tp --tl manually below to run_xsim.sh.

/tools/Xilinx/Vivado/2023.2/bin/xsim --maxdeltaid 100000 --tp --tl --noieeewarnings myproject -tclbatch myproject.tcl -view myproject_dataflow_ana.wcfg -protoinst myproject.protoinst

Unfortunately, these are not directly supported in hls4ml and need to be added manually.
