Calling LabVIEW FPGA VIs From TestStandPrimary Software: TestStandPrimary Software Version: N/A Primary Software Fixed Version: N/A Secondary Software: LabVIEW Modules>>FPGA Module
Problem: I have created a project using LabVIEW FPGA that contains a Host VI and a FPGA VI. When I attempt to call the Host VI in TestStand, the step says the VI is broken. How can I resolve this and call my FPGA code from TestStand? Solution: The Host VI is broken because it doesn't contain the Input/Output reference of the FPGA device on its own. The reference to FPGA device is contained within the project and when trying to call the VI from outside the project, it lacks the appropriate deployment information. To correct this issue you will need to create a bitfile of your FPGA VI and then have the Host VI point to the bitfile. This is done automatically when you compile the VI which exists under an FPGA target. To find the location of the bitfile, right-click the VI in the Project Explorer window and select Target Specific Properties from the shortcut menu. You can do this by using the Open FPGA Reference from within the Host VI, right-clicking on the Open FPGA Reference and selecting the bitfile you created. You can then call the Host VI from TestStand. For more information on creating and using bitfiles, see the LabVIEW FPGA Help.
