5.1. ALTCLKCTRL IP Core Parameters
Parameter | Value | Description |
---|---|---|
How do you want to use the ALTCLKCTRL | For global clock, or For external path | Specify the ALTCLKCTRL buffering mode. You can select from the following modes:
|
How many clock inputs would you like? | 1, 2, 3, or 4 | Specify the number of input clock sources for the clock control block. You can specify up to four clock inputs. You can change the number of clock inputs only if you choose For global clock option. |
Create ‘ena’ port to enable or disable the clock network driven by this buffer | On or Off | Turn on this option if you want to create an active high clock enable signal to enable or disable the clock network. |
Ensure glitch-free switchover implementation | On or Off | Turn on this option to implement a glitch-free switchover when you use multiple clock inputs. You must ensure the currently selected clock is running before switching to another source. If the selected clock is not running, the glitch-free switchover implementation will not be able to switch to the new clock source. By default, the clkselect port is set to 00. A clock must be applied to inclk0x for the values on the clkselect ports to be read. |
