What is API functions between "Arria10 dev board" and its Win10 BTS GUI tool

Hello,

in Arria10 GX Dev Kit, there 's one Win10 GUI tool named "BTS", which can be used to run verifcation of A10 GX DEMO board. Now we need understand how the PC BTS GUI communicate with the FPGA board logic, so w can design our own "BTS" alike tool, to run automatic test against Arria10 Devices.

is there any document to describe it ？ If intel can provide BTS source code, wjich will be more helpful for customers. Thanks a lot
