That page contains the more general tool that I was thinking about, and on the left are links to more specific ones too. The Arduino isn't viewed as an important instrumentation target, so these tools won't directly reference it.
But generally, this is the tool that was developed to go from LV to C/C++ code in order to target specialized processors such as DSPs and micros. Similarly, the FPGA module goes from LV to VHDL to target even more specific silicon.
Back to micros

This is an example of it in use.

And this is someone using one tool to program the Arduino, but using LV to integrate it with their computer
