5.2. ALTCLKCTRL Intel® FPGA IP Ports and Signals
Port Name | Condition | Description |
---|---|---|
clkselect[] | Optional | Input that dynamically selects the clock source to drive the clock network that is driven by the clock buffer. Input port [1 DOWNTO 0] wide. If omitted, the default is GND. If this signal is connected, only the global clock network can be driven by this clock control block. The following list shows the signal selection for the binary value:
|
ena | Optional | Clock enable of the clock buffer. If omitted, the default value is VCC. |
inclk[] | Required | Clock input of the clock buffer. Input port [3 DOWNTO 0] wide. You can specify up to four clock inputs, inclk[3..0]. Clock pins, clock outputs from the PLL, and core signals can drive the inclk[] port. Multiple clock inputs are only supported for the global clock networks. |
