Owning Palette: FPGA Module VIs and Functions

Requires: FPGA Module. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.

Use the Timing VIs to control the execution timing of FPGA operations.

Note  This palette is specific to FPGA targets and contains a subset of the VIs and functions that are on this palette when you edit a host VI.
Palette ObjectDescription
Loop TimerWaits the value you specify in Count between loop iterations. You can call this function in a loop to control the loop execution rate. If an execution instance is missed, such as when the logic in the loop takes longer to execute than the specified interval, the Loop Timer Express VI returns immediately and establishes a new reference time stamp for subsequent calls. To manage execution rates with the Loop Timer Express VI, place the Loop Timer Express VI in the first frame of a Flat Sequence structure or a Stacked Sequence structure and put the rest of the code in subsequent frames.
Tick CountReturns the value of a free running counter in the units specified. The output and internal counter are both of the configured width.
WaitDelays for a certain time interval before the output data dependence becomes valid.
