For boundary frequencies, choose the higher delay.
DLL Outputs are used in these instances to describe the outputs: CLK0, CLK90, CLK180, CLK270, CLK2X, CLK2X180, and CLKDV.
DFS Outputs are used in these instances to describe the outputs: CLKFX and CLKFX180.
CLKIN must be present and stable during the DCM_RESET.
This only applies to production step 1 LX and SX devices. For these devices, use the design solutions described in Answer Record 21127 for support
of longer reset durations. Production step 2 LX and SX devices and all production FX devices do not have this requirement.
For production step 1 LX and SX devices, use the design solutions described in Answer Record 21127 for support of longer durations of stopped
clocks. For production step 2 LX and SX devices and all production FX devices, the ISE software automatically inserts a small macro to support
longer durations of stopped clocks.
For all stepping levels, once the input clock is toggling again and stable after being stopped, DCM must be reset.
