Registers or local variables to communicate sctl loops inside the FPGA

[Imanol]

Hello all,

What is it better, to use registers to communicate between sctl loops or to use local variables? Is there any difference between them when the implementation inside the fpga is done?

Thanks in advance,

Imanol

If you implement your code in the top level FPGA VI you should avoid to use local variables because their front panel elements implement the interface to the Host and will need more resources.

Keep in mind that you can use SCTL's within While loops to optimize your code.

Hope it helps
