How are signals PHASE_1, 2, and 3 used in the ST-EVAL-ESC01 design?

In trying to create a design from scratch using the motor control workbench, I have tried to verify what I see in the ST-EVAL-ESC01 design documentation. In that design (https://www.st.com/en/embedded-software/stsw-esc001v1.html) that there are three phase_x signals, three curr_fdbk x signals, and three vshunt_x_filtered signals. See here:

In a startup program using the STM32F303 and Workbench 5.1, it is pretty clear that the current feedback is accounted for (A0/A1/A2) and the over current protection (A7/B9/B11) is for the vshunt_x_filtered signals. Here:

I see nothing in the workbench that accommodates the PHASE_x signals.

What are they used for (if at all) in this design?

Thanks,

Mr. Yan

This was resolved by Cedric in a separate thread. The PHASE_X signals are not used in this design (i.e. for FOC control).

The question has been moved from the section "Motor Control Hardware" to the "STM32 Motor Control" section (the question is about the STM32 MC SDK).
