Hi Wojciech,

can you reproduce the same issue when latest SW version is used
(THCC 2025.2) ?

Answered: Does the THIL API support setting a fixed circular buffer size (FIFO overwrite) for captures?

Thu, 03 Apr 2025 13:21:05 +0000

Hi,

Currently, HIL API start_capture doesn't support circular buffer behavior or size limiting.

start_capture expects queue.Queue or list object as dataBuffer, so in theory custom container can be created (which implements list or Queue interface), with some additional logic like circular data buffer.

Answered: Missing SchematicAPI get_model_init_code method

Hi Radovan,

There is a way to do this by using mdl.set_ns_var() and mdl.get_ns_var() functions.

Let say your variable is named temp_var. To read it you can call:

With mdl.get_ns_var("temp_var") you will get value of that variable.

Problem occurs when you want to change it. If you just call mdl.set_ns_var("temp_var", 10) your variable will still be set on the previous value after compile. Reason for this is that during compilation model init is called and it will overwrite changed variable.

What you could do is to leave model init empty and than you will not face this problem, however if you try to compile it through schematic, you will get an error because there is no variable defined.

Better approach is to check first if variable already exists, in model init of course. Something like this:

if "temp_var" not in mdl.get_ns_vars():
temp_var = 1

In this case you will be always able to load compile model through schematic, or through API. If you dont set ns varable, temp_var will be set to 1, but if you set with set_ns_var to, lets say 10, it will be 10.

Drawback of this is that you will not be able to read initial value, at least without compiling the model.

Hello,

Do you have more information regarding this problem?

Hi Laurin,

I'm not sure which way you generated and exported your plots, but adding of the plots in .png format should be possible using attach_figure function from TyphoonTest API: documentation

I've never used that function with pdf reports, but I'd expect it to work the same way it does for Allure reports.

Hello Christian,

Do you have both HIL devices connected to the same PC?

Hi Bikas, welcome to the forum. Is your intention to use an actual HIL device in this project? Are RL model + LVRT comprising a controller model that you plan to load onto some DSP/hardware target?
