Hi Waran,
The single-cycle timed loop (SCTL) is a special case of the new LabVIEW timed loop structure. It is available in version 7.1 of LabVIEW FPGA ModuleThis loop executes all functions inside it within one 25 nsec �tick� of the 40 MHz global clock.
If you are writing you code to be compiled and run on an NI-RIO target, and if the functions that you use are able to be executed in one tick, all of your code in the loop should be executed in 25ns.
I hope that this helps.
Regards,
P.J.
