Error (suppressible): (vsim-10000) Unresolved defparam reference to 'lvds_rx_reg_setting' in ALTLVDS_RX_component.lvds_rx_reg_setting - Error (suppressible): (vsim-10000) Unresolved defparam reference to 'lvds_rx_reg_setting' in ALTLVDS_RX_component.lvds_rx_reg_setting Description Due to a problem in the Intel® Quartus® Prime Standard Edition Software version 19.1 and later, this error will be issued in register transfer level (RTL) simulation using ModelSim when the design includes the ALTLVDS_RX IP core. When using another simulator than ModelSim, an error for 'lvds_rx_reg_setting' will be issued as well. Resolution To avoid this error, use one of the following workarounds: • Use the suppress option along with vsim command when using the ModleSim ( ex. vsim -suppress 10000 ) Or • Remove the lines for ALTLVDS_RX_component.lvds_rx_reg_setting from the top RTL of the ALTLVDS_RX IP 1) Open the top RTL of the ALTLVDS_RX IP using a text editor. 2) Remove the following lines: <Verilog> ALTLVDS_RX_component.lvds_rx_reg_setting = "ON" <VHDL> lvds_rx_reg_setting : STRING; and lvds_rx_reg_setting => "ON", This problem has been fixed in the Intel® Quartus® Prime Standard Edition Software version 22.1.
