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 Memory functions to access memory on an FPGA. Use the FIFO functions to transfer data.

Note This palette is specific to FPGA targets.

The VIs and functions on this palette can return general LabVIEW error codes, specific FPGA Module error codes, or error codes specific to the FPGA target.

Palette Object	Description
FIFO Constant	Use the FIFO constant to specify a FIFO item on the block diagram. To specify the FIFO item, click the arrow button on the right side of the constant and select a FIFO item from the shortcut menu.
FIFO Method Node	Invokes a FIFO method or action on an FPGA VI. You can use methods such as write, read, clear, enable and disable on FPGA FIFOs. The methods you can choose from depend on the FIFO you specify.
Memory Constant	Use the Memory constant to specify a memory item on the block diagram. To specify the memory item, click the arrow button on the right side of the constant and select an item from the shortcut menu.
Memory Method Node	Invokes a method on a memory block in the FPGA. Use methods to write or read memory blocks.
VI-Defined FIFO Configuration	Represents a VI-defined FIFO. Right-click the node and select Configure from the shortcut menu to display the FIFO Properties dialog box. Use the FIFO Properties dialog box to configure the VI-defined FIFO.
VI-Defined Memory Configuration	Represents a VI-defined memory item. Right-click the node and select Configure from the shortcut menu to display the Memory Properties dialog box. Use the Memory Properties dialog box to configure the VI-defined memory item.
