Design Check: PMA Direct Messages (Titanium)

When you check your design, the Interface Designer applies design rules to your configuration settings. The following tables show some of the error messages you may encounter and explains how to fix them.

pma_direct_rule_bonding_mode (error)

Message Bonding mode <x2,x4> requires <2,4> lanes configured in the same QUAD
To fix Bonding mode x2 requires 2 lanes in the same quad to be configured; bonding mode x4 requires 4 lanes in the same quad to be configured
Message Bonding mode x2 is valid on lane resource pairs LN0,LN1 or LN2,LN3 of the same QUAD only
To fix Only certin lanes can be bonded together. Check that the lanes you are trying to bond are set to the correct resources. Refer to "Bonding Mode" in the Titanium PMA Direct User Guide for details.
Message Mismatch properties against lane instances in the same bonding <bonding_mode>: <list of mismatched parameters>
To fix Lanes that are bonded must have the same preperties. Update the listed parameters to ensure that the highlighted mismatched properties are identical for all PMA Direct lane instances within the same bond
Message Bonding mode x8 requires all lanes in the quad to be configured
To fix Create new instances and assign remaining resource in the same quad, or change the lane bonding mode. Bonding mode x8 requires you to configure all 4 lanes in 2 quads.
Message Expected Q# lanes to be configured as part of bonding mode x8
To fix Create new instances and assign resources for the quad, or change the bonding mode. Bonding mode x8 can only use quad pairs from the following list: (Q0, Q1), (Q2, Q3), (Q1, Q2).
Message Bonding mode x8 requires 8 lane instances to be configured
Bonding mode x8 requires 8 lane instances but found <number of instances>
To fix Change the bonding mode for the other lane instance to ensure that there are 8 PMA Direct instances with bonding mode x8 for the correct quad-lane resource assignments For x8 mode, (Q0, Q1), (Q2, Q3), (Q1, Q2) are the available quad pairs.
Message Clock resource is not selected for bonding mode <bonding mode>
To fix Turn on the Used as Clock Resource option for one of the PMA Direct instances in the Pins tab > Clock and Reset subtab.
Message Only 1 clock resource is allowed to be selected for bonding mode <bonding mode>, selected instances: <list of instances>
To fix You can only use one PMA Direct clock as a clock signal to the core.Turn off the Used as Clock Resource for all the listed instances except for the one that you want to use as a clock resource.

pma_direct_rule_data_rate (error)

Message Data rate exceeds maximum limit: <max> Gbps
To fix Re-assign the data rate by selecting a preset

pma_direct_rule_data_rate_timing_model (error)

Message Data rate greater than 10.3125 Gbps is not supported in timing model <speed grade>
To fix Choose a lower data rate or select a device with a supported timing model (C4, I4, C4L, or I4L) if available.

pma_direct_rule_external_clock (error)

Message PMA Direct only allows external clock 0 to be configured.
To fix In the <project>.peri.xml file, update the value of PMA_CMN__cmn_plllc_gen_preg__cmn_plllc_pfdclk1_sel_preg to Refclk 0.

pma_direct_rule_hw_drc (error)

Message Invalid value assigned to the following parameters: <list_of_parameters>
Found <#> HW Errors: <list_of_errors>
To fix Enter valid values for the parameters.

pma_direct_rule_hw_drc (warning)

Message Found <#> HW Warnings: <list_of_errors>
To fix Enter valid values for the parameters.

pma_direct_rule_inst_name (error)

Message Instance name is empty.
Valid characters are alphanumeric characters with dash and underscore only
To fix Enter a valid pin name.

pma_direct_rule_invalid_hex_value (error)

Message The following hexadecimal parameters has invalid value: <list_of_parameters_with_error_message>
To fix Update the parameters to use a hexadecimal value in a valid range.

pma_direct_rule_osc_clock (error)

Message Oscillator is required to be configured
To fix Create an Oscillator instance with no enable pin.

pma_direct_rule_pll_config (error)

Message Invalid PMA Direct preset with combination of Data Rate: <data_rate>, SerDes Width: <serdes_width> and Reference Clock Frequency: <ref_clk_freq> MHz
To fix Select a preset to update the data rate, SerDes width, and reference clock frequency.
Message PMA Direct selection has invalid PLL config settings. Please reassign the preset: <list_of_parameters>
To fix Choose the preset again.

pma_direct_rule_rclk (error)

Message Use global clock due to unroutable clock loopback on regional clock with bonding mode:<bonding_mode> Mode: <mode> on pins: <list of pin types>
To fix Change the connection type for the listed pin types

pma_direct_rule_resource (error)

Message Resource name is empty
To fix Assign a resource.
Message Resource is not a valid PMA Direct device instance
To fix Assign the instance to a resource that exists in the device.

pma_direct_rule_res_usage (error)

Message Resource name conflict with instance <instance name>
To fix The resource is already used. Choose another one.
Message Resource conflicts with PCI Express resource <resource name>
To fix You cannot use the same resource for PCI Express and PMA Direct at the same time. Update one of the resources. (PCI Express uses quad 0 and quad 2.)

pma_direct_rule_rx_clock (error)

Message Interface Receive Clock Input pin name cannot be empty
To fix Add a pin name for the instance in the Block Editor > Pins > Interface Receive Clock Input Pin Name box.

pma_direct_rule_tx_clock (error)

Message Interface Transmit Clock Input pin name cannot be empty
To fix Add a pin name for the instance in the Block Editor > Pins > Interface Transmit Clock Input Pin Name box.
Message Interface Transmit Clock Input cannot be used with bonding mode x8
To fix In x8 mode you cannot use the TX pins. Choose Mode > RX FIFO, which filters out the TX pins. Clear the Interface Transmit Clock Pin Name field.

pma_direct_rule_x8_mode (error)

Message Bonding mode x8 is only supported in Mode RX FIFO
Mode RX FIFO is only supported with bonding mode x8
To fix Change the bonding mode and the mode.

pma_direct_rule_x8_mode_rx_clk_conn_type (error)

Message Bonding mode x8 does not support rclk clock input connection type
To fix Change the RX clock input connection type and bonding mode.

pma_direct_rule_x8_quad_pair (error)

Message Bonding mode x8 on quad Q# expected to pair up with instances of one of the following quads: <list of quad names>
Bonding mode x8 on quad Q# expected to pair up with quad Q#
To fix Change the bonding mode for the listed quads, change the bonding mode of the current instance, or use a different quad resource.
Message Bonding mode x8 requires 2 quads with PMA Direct configuration
To fix Change the bonding mode for the other quad resource, or create an instance of another quad resource that adds up to 8 lanes in the bond.

common_quad_rule_apb_clock (error)

Message APB Clock pin cannot be empty
To fix Enter the clock name in the Block Editor > Common Properties > APB tab.

common_quad_lane_rule_inst_name (error)

Message Instance name is empty.
Valid characters are alphanumeric characters with dash and underscore only
To fix Enter a valid pin name.

common_quad_lane_rule_pin_name (error)

Message The following pin(s) is/are identical across different QUAD: <list of pin and resource names>
To fix Check the pin names to in the Block Editor > Common Properties tab to ensure that you are not using the same name(s) as the lane-specific pin(s).

common_quad_lane_rule_protocol (error)

Message Multiple lane-based protocol in the same quad is not supported
To fix All of the lanes in a quad must be configured for the same protocol; you cannot use multiple protocols in the same quad. Change protocol for the lanes so that they are all the same. Alternatively assign a resource from a different quad.

common_quad_rule_phy_reset_pin (error)

Message PHY Quad Reset pin cannot be empty when PHY Quad Reset Pin is enabled
To fix Enter the reset pin name in the PMA Direct block > Common Properties tab > Clock and Reset sub-tab > PMA Quad Reset Pin Name box or turn off the Enable PHY Quad Reset Pin option.

common_quad_lane_rule_pma_direct_pll_config (error)

Message Found <pma direct instance> in the same <quad resource name> with different PLL configuration settings
To fix All of the lanes in the same quad must have the same preset settings. Change the preset for the listed PMA direct instances to be the same setting.
