4.2.2.2. Port Mapping Reference
The following table shows the mapping between MMCM UltraScale* ports, created with the Xilinx* IP Catalog, and PLL ports in Intel® Stratix® 10 device, created with the IP Catalog.
Xilinx* MMCM Core Port | Intel® FPGA Intel® FPGA IOPLL IP Core Port | Description |
---|---|---|
clk_in1 | refclk | First clock input |
clk_in2 | refclk1 | Second clock input |
clkfb_in | fbclk | External clock feedback |
clkfbout | fboutclk | Feeds into the feedback port |
— | activeclk | Output signal that indicates which reference clock source the I/O PLL uses |
clk_in_sel | extswitch | Switch between input clock ports |
reset | rst | Asynchronous reset port |
clk_out1, clk_out2, clk_outX | outclk_[] | Clock frequency output ports. Xilinx* MMCM has fixed settings for most outputs, and you can configure the Intel® FPGA IOPLL IP core to suit them. |
clkinstopped | clkbad[1..0] | Indicates whether the clock input signal stopped switching |
clkfb_stopped | — | Specifies whether the feedback clock stopped |
locked | locked | Specifies whether the PLL is locked |
— | adjpllin | Input signal that feeds from upstream I/O PLL |
— | cascade_out | Output signal that feeds into downstream I/O PLL |
— | zdbfbclk | Bidirectional port that connects to the mimic circuitry. You connect this port to a bidirectional pin that is placed on the positive feedback dedicated output pin of the I/O PLL. The zdbfbclk port is available only if the I/O PLL is in zero-delay buffer mode. |
Xilinx* MMCM Core Port | Dynamic Phase Shift Ports in Intel® FPGA IOPLL | Description |
---|---|---|
psclk | scanclk | Specifies clock that drives the dynamic phase shift operation |
psen | phase_en | Start dynamic phase-shift operation |
psincdec | updn | Specifies direction of phase shift operation |
— | cntsel | Specifies counter for dynamic phase shift operation |
— | num_phase_shift | Specifies number of phase shifts per dynamic phase shift operation |
psdone | phase_done | Specifies completion of dynamic phase shift operation |
power_down | — | Enables power_down input port for user selection |
