hls 2018.2: Why does the standalone driver append _V to axilite variables?

Hi folks,

I have synthesized an IP core through HLS 2018.2. Perhaps things have changed in this version, but I noticed that all the APIs generated for the standalone driver seem to append (_V) to the name of each variable. I do not recall this was the case in previous versions and having rechecked UG902 (v2018.2) July 2, 2018 Table 1-10: C Driver API Functions, the API should have the form :

- XDUT_Set_ARG

vs what I am getting:

- XDUT_Set_ARG_V

This doesn't seem to affect the functionality of the IP core.

 

Any idea why _V is appended to variable names?
