gpio_rule_deserialization (error)
Message Register Option has to be enabled when using deserialization
To fix You cannot use deserialization unless the Register Option is set to register. Either change the
option or do not use deserialization.
Message Deserialization canot be used with DDIO Option
To fix If you are using serialization, you cannot also use DDIO. Either disable deserialization or set
Double Data I/O Option to none.
Message Serial and parallel clock names are required to be non-empty with deserialization
To fix You need to specify the parallel and serial clock names if you are using deserialization.
Message Deserialization is not supported due to PLL is not available
To fix When the GPIO is using the deserializer, the serial and parallel clock signals must come from
a PLL. You need to make two PLL clock outputs available to the GPIO.
Message Serial and parallel clocks cannot be the same clock
To fix Use different PLL output clocks for the signals.
Message Serial and parallel clock names are not PLL output clocks
Serial clock name is not a PLL output clock
Parallel clock name is not a PLL output clock
To fix When the GPIO is using the deserializer, the serial and parallel clock signals must come from
a PLL. You need to use two PLL clock outputs, one for serial and one for parallel.
Message Serial and parallel clocks are not from the same PLL instance
To fix Use PLL output clocks from the same PLL for the serial and parallel clocks.
Message Serial clock phase shift <deg> is not one of the valid values: 45, 90, 135
To fix Choose one of the values in the message.
Message One of the clock frequencies is 0
To fix Change the clock frequency to be something other than zero.
Message Serial clock frequency has to be 4 times faster than parallel clock
To fix Change the PLL output clock frequencies such that the serial clock is 4 times faster than the
parallel clock.
gpio_rule_bus_hold (error)
Message Bus hold is only supported on 1.2/1.5/1.8 V LVCMOS I/O standard HSIO only
To fix You cannot use the bus hold option for the I/O standard you chose. Either turn off Enable Bus
Hold or use a different I/O standard.
gpio_rule_differential_stl_inout (error)
Message For inout mode with differential STL, output enable (N) pin name must be configured
To fix Specify the output enable pin name.
