Titanium Interfaces User Guide
gpio_rule_inout_mode (error)
Message For inout mode, both output and output enable must be configured
To fix When using a GPIO block in inout mode, you need to set the options for the output and
output enable (as well as the input).
Message For inout mode, both output pin name and output enable pin name must be configured
To fix Specify a valid name for the output pin and output enable pin.
Message Output enable pin name with square bracket does not match a bus name with index
To fix You probably used a bracket [ or ] in the pin name. Rename the pin without brackets.
gpio_rule_clkout_mode (error)
Message For clkout mode, output must be configured
To fix When using a GPIO block in clkout mode, you need to set all of the options.
Message For clkout mode, output clock pin name must be configured
To fix When using a GPIO block in clkout mode, you need to specify a valid pin name for the ouput
clock.
gpio_rule_output_clock (error)
Message Output is registered but clock pin name is empty
To fix If you choose register or inv_register as the Register Option, then you also need to specify an
output clock pin name.
Message Output enable is registered but clock pin name is empty
To fix If you are using a GPIO in inout mode, you need to specify the output enable pin name if you
set the output enable to register.
Message Output is registered but clock pin name has illegal character
Output enable is registered but clock pin name has illegal character
To fix Use valid names for these pins.
Message Output clock pin name is not the same as output enable clock pin name
To fix For a GPIO block in inout mode, you need to use the same pin names for the output clock pin
and the output enable clock pin.
Message Output clock inversion is not the same as output enable clock inversion
To fix For a GPIO block in inout mode, if you invert the output clock pin you also need to invert the
output enable clock pin. Similarly, if you do not invert the output clock pin, you cannot invert
the output enable clock pin.
gpio_rule_unused_mode (error)
Message For unused (none) mode, its state needs to be configured
To fix If you set a GPIO block mode to none, you need to set the Unused State. The default is input
with weak pull-up. You can change this setting globally by clicking the GPIO category in the
Design Explorer and setting the Unused State option.
