Question regarding MAX10 and clock switchover

Hi,

May I know what device you are using? You may use ALTCLKCTRL for clock swicthover. ALTCLKCTRL represents clock buffers that drive the Global Clock Network, the regional Clock Network, and the dedicated External Clock Path. You can select up to 4 clock inputs.

Here is the IP user guide for reference.
