TINA/Spice/TIDA-01627: TIDA-01627 reference design Schematic and Block Diagram issue

Part Number: TIDA-01627

Tool/software: TINA-TI or Spice Models

Hello , I`m Leon.

Nowadays, I am checking TIDA-01627 circuit design.

Q1: I found the ‘SW_SIG' seems like a signal but I can not found where is it link to.

Is it important to realize some function? or it can be ignored.

I would appreciate it if you could answer this question.
