Design Check: MIPI Lane Messages
When you check your design, the Interface Designer applies design rules to your
configuration settings. The following tables show some of the error and warning messages
you may encounter and explains how to fix them.
mipi_ln_rule_resource (error)
Message Resource name is empty
Resource <name> is not a valid MIPI LANE <Rx/Tx> device instance
To fix Choose a valid resource.
mipi_ln_rule_group_clock (error)
Message No clock lane was configured in the MIPI LANE group <group>
No clock lane was configured in the same MIPI LANE group
To fix The minimum requirement to create a MIPI interface is one clock lane and one data lane. For
RX, they must also be in the same MIPI group. Add a clock lane.
mipi_ln_rule_group_data (error)
Message Instance is not a resource associated to a MIPI LANE Rx group
Instance is not a valid MIPI LANE data lane resource
To fix In some packages there are not enough MIPI resources in a group to have both a clock and
a data lane for RX interfaces. In those cases, you cannot use that pin as a MIPI lane. Choose
another resource. See MIPI Groups by Package on page 99.
mipi_ln_rule_rx_clk_conn (error)
Message Connection type <type> is not supported by the resource
The resource does not support clock lane mode
To fix Not all resources support both GCLK and RCLK connection types. Use the Resource Assigner
to pick a different resource that supports GCLK and RCLK.
lvds_rule_rx_distance (error)
Message These HSIO GPIO must be placed at least 1 pair away from MIPI LANE <name> in order to
avoid noise coupling from GPIO to MIPI LANE: <violated list>
To fix When using HSIO pins as GPIO, make sure to leave at least 1 pair of unassigned HSIO pins
between any GPIO and HSIO used as MIPI RX lanes in the same bank. This separation reduces
noise.
mipi_ln_rule_rx_empty_pins (error)
Message Empty pin names found: <list>
To fix Specify the missing pin names in the list.
mipi_ln_rule_rx_param (error)
Message Invalid parameters configuration: <features>
To fix One of the parameters you set was incorrect. Review any other errors for details.
