FPGA targets can support more than one base clock, although some targets add only a subset of supported base clocks to the Project Explorer window when you add the target. If the FPGA target you use does not include the FPGA base clock you need in the Project Explorer window when you add the target to a LabVIEW project, you can add a new base clock to the LabVIEW project.

Complete the following steps to add a new base clock to a LabVIEW project.

1. Create a new project or open an existing project.
2. Add an FPGA target to the project.
3. Right-click the FPGA target and select New»FPGA Base Clock from the shortcut menu. The FPGA Base Clock Properties dialog box appears.
4. Select an available clock from the Resource pull-down menu.
5. Click the OK button. The new FPGA base clock appears in the Project Explorer window below the FPGA target.

You now can set the new base clock as the top-level clock in the project.
