gpio_rule_serial_output_clk (error)
Message Output clock inversion is not allowed with serialization enabled
To fix If you use serialization, you cannot also invert the clock. Turn off the Inverted option.
gpio_rule_static_input_delay (error)
Message Static delay, <int> is outside of limit (0-15) for non-Differential HSTL/SSTL I/O Standard
Static delay, <int> is outside of limit (0-63) for Differential HSTL/SSTL I/O Standard
To fix The static input delay you selected is not valid. Use a number in the range specified in the
message.
gpio_rule_io_standard_valid (error)
Message I/O standard <value> is not supported in bank <bank>
To fix You get this error when you choose an I/O standard that is not supported in the bank. You
need to choose another I/O standard or pick a resource in another bank. See Titanium I/O
Banks on page 21 for the voltages supported in each bank and Types of GPIO on page 39 fo
rthe I/O standards the GPIO support.
gpio_rule_hsio_usage (error)
Message HSIO resource <name> was assigned to GPIO, LVDS and MIPI LANE
HSIO resource <name> was assigned to both GPIO and LVDS
HSIO resource <name> was assigned to both GPIO and MIPI LANE
To fix You get this error if you try to use the same resource for more than one block type. Remove
blocks so that you only are only using the resource once.
gpio_rule_io_standard_stl (error)
Message This resource is reserved as vref for bank <name>. Use a different resource to configure
single ended HSTL/SSTL
To fix Some resources can be used as the VREF for an I/O standard. If you are using an I/O standard
that uses a VREF pin, you must use this resource as a VREF. Choose another resource for the
GPIO function.
Message GPIO <name> has to be configured as vref input mode to support I/O standard <iostd>
GPIO <name> has to be configured as vref input connection type to support I/O standard
<iostd>
GPIO <name> has to be configured as vref input to support I/O standard <iostd>
To fix If you are using an I/O standard that uses a VREF pin, you must use this resource as a VREF.
Configure the GPIO as an input and choose vref as the Connection Type.
Message I/O Standard <iostd> cannot be used due to unbonded vref resource on the same bank
<name>
I/O Standard <iostd> cannot be used due to vref resource not bonded out
To fix If a VREF pin is not available in the I/O bank (e.g., it is not in the FPGA/package you chose),
you cannot use an I/O standard that requires it. Instead choose a different I/O standard for the
GPIO or a resource in a different I/O bank that has a VREF pin bonded out. .
