Tri-state Conduit bridge signals are not matching with the generic tri-state controller

Hi,

we are using tri-state conduit component to interface to the FIDO/Ethernet switch in Arria 10 SoC. But Generic ti-state controller master port-tcm signals and tri-state conduit bridge slave port -tcs signals are not matching and Qsys system connection is providing the errors. Please see the attached figures where you can see the differences and Qsys errors. Tri-state bridge IP has only request and grant signals in tcs port.it doesnt have data_in, data_out and other signals.

Please let us know why this is happening.

Thank you

    Hi Nathan,

    Thank you for the reply. quartus version is Quartus Prime Pro 18.0 .

    I have solved the issue by using Synch all option in system Info tab in Qsys .

    Hie,

    I don't have details on your full QSYS design, hence I believe you have identified the problem which is the conduit component used does not have an interface that matches the Generic Tristate Controller. If your Quartus version don't have a tri-state conduit component that matches, then you will need to build the bridge yourself. Do let me know you Quartus version, so I can check and advice accordingly.

    Regards,

    Nathan
