pll_rule_dynamic_shift_pin (error)
Message Dynamic phase shift is enabled but missing pin names: <list>
To fix For a PLL output, if you are turn on Dynamic for the phase shift, you also need to specify
names for the SHIFT, SHIFT_SELECT, and SHIFT_ENA pins.
pll_rule_extfb_io (error)
Message External feedback and reference clock have to be of the same instance type and IO standard
To fix Use the same I/O standard for the external feedback clock and reference clock GPIO blocks.
pll_rule_extfb_resource (error)
Message There can only be one configured resource for external IO feedback
To fix In external feedback mode, you can only specify one clock out pin for feedback.
Message External IO feedback resource <name> is not configured as pll_extfb connection
To fix In the GPIO block that is your feedback resource, set the Connection Type to pll_extfb.
Message The resource for external IO feedback is not configured
To fix Add a GPIO block in input mode, set the Connection Type to pll_extfb, and assign it to a
resource that supports the pll_extb connection type.
pll_rule_fb_freq (error)
Message Feedback frequency <#>MHz is out of range. Min=<>MHz Max=<>MHz
To fix The feedback frequency needs to be within the range specified. Adjust the parameters to
meet that requirement.
pll_rule_feedback_clock (error)
Message Feedback clock name is required with non-internal feedback
To fix You need to specify a clock pin name when you are not using internal feedback mode.
Message Feedback clock name <string> is not from the same PLL
To fix You need to use one of the output clocks from the PLL you are configuring as the feedback
clock. You cannot use an output clock from a different PLL.
Message Feedback clock in local mode has to connect to output clock 0
To fix When Feedback Mode is Local, you can only use output clock 0 for feedback.
Message Feedback clock <string> is not connected to pll clkout
To fix The feedback clock you are using needs to be one of the output clocks from the PLL.
pll_rule_feedback_mode (error)
Message Internal feedback mode is not supported
To fix You may receive this error when configuring an interface with the API. Do not use internal
feedback mode as it's not supported.
