Custom bitfiles and FPGA VIs must have a filename in the following format:

sitfpga Device LabVIEWVersion DeviceType CustomPart.lvbit.

This filename consists of the following components:

• sitfpga defines the VI as a custom FPGA VI for the LabVIEW Simulation Interface Toolkit.
• Device is the FPGA device on which you want to run the simulation. For CompactRIO targets, Device is the type of chassis, for example, cRIO-9103.
• LabVIEWVersion is 8_5.
• DeviceType is master or slave, depending on the type of FPGA device.
• CustomPart is any custom text you specify.

For example, the filename sitfpga PXI-7831R 8_5 master MyFPGA.lvbit specifies this FPGA lvbit file runs on the NI PXI-7831R device using LabVIEW 8.5 and is a master VI.

Additionally, you must place custom bitfiles in the labview\vi.lib\addons\Simulation Interface\_IOTypes\NI FPGA\FPGA IO VIs\Bitfiles\ directory.

If you do not follow these rules, the SIT Connection Manager dialog box does not recognize the custom FPGA bitfile, and you cannot create mappings between a model DLL and the FPGA device.
