FPGA optimization of unhooked indicators

[280Z28]

If I have a reentrant sub-vi with outputs that aren't hooked up in a certain use case (say it has 2 outputs, but I'll only need 1 or the other, not both, for any given usage in my code), will the FPGA compiler remove that section of code (and whatever computation in the sub-vi that served no purpose except to calculate that unused output) wherever terminals aren't used to save space?

Also, are basic math functions that are hooked up to constants calculated and eliminated from taking space/time on the FPGA for the calculation?

What about things like the Linear Interpolation block? If y0, y1, and x are hooked up to numbers that can be determined at compilation time, is the block calculated and replaced by just a constant like it can be?

280Z28 hello.

LabVIEW will execute all the function/VIs on its block diagram. It does not matter if an indicator is connected or not.

Functions that are hooked up to constants are not calculated before-hand in order to eliminate time/space consumption. The functions/VIs will still get computed. However, if you have a function and the inputs are all constants, you are better off calculating the result of the computation, then using the constant value in your FPGA application. That way you by-pass the computation by converting it to a simple constant value.
