QuestaSim (Intel Starter) : Bad default binding for component instance "ALTLVDS_RX_component

Steve-534B46

Hello,

 

I am trying to simulate a description containing the ALTLVDS_RX primitive.

I launch the simulation through Tools->Run simulation tool->RTL simulation

 

When I start the simulator with the following command:

vsim -gui work.hsssb_tb -t 1ps

The compilation stops with the following error:

Error (suppressible): C:/Local_repositories/HSSSB/Data_rx.vhd(128): (vopt-1271) Bad default binding for component instance "ALTLVDS_RX_component: altlvds_rx".
(Component generic "lvds_rx_reg_setting" is not on the entity.)

 

Could someone help me to find the origin of this error?

 

Thanks in advance

 

Regards,

 

Steve

Hello Steve,

 

We have a KDB about this error. Please check on the KDB below and follow the workaround suggested: Error (suppressible): (vsim-10000) Unresolved defparam reference to 'lvds_rx_reg_setting' in ALTLVDS...

 

Hopefully this workaround will be able to resolve your issue.

 

Thank you

Can you show the code the error is referencing?

Hello,

Here are the files:

  • HSSSB.vhd is the top level entity,
  • receiver is a wrapper for the Data_rx entity generated by MegaWizard
  • Data_rx is the ALTLVDS_RX IP customize through MegaWizard

Hello,

 

Despite my research, I can't find the origin of the missing entity "lvds_rx_reg_setting" in my RTL simulation (Component generic "lvds_rx_reg_setting" is not on the entity).

I really don't understand why QuestaSim can't find this generic component. If someone has an idea, I'm interested because I'm not making any progress on my design.

 

Regards,

Hello,

 

Is someone at Intel able to give an answer to this problem?

Today, my design does not progress because I cannot debug it. Indeed, the simulator can't find one of the entities contained in the ALTLVDS_RX.

 

Thanks in advance

 

Best regards,
