Question about Monitor

--- Quote Start ---

Some clarifications before I get to conduits:

When I create system that can be synthesized on an FPGA the components of my system is glued by the Avalon interfaces right?

--- Quote End ---

In SOPC Builder or Qsys, when you click connections between components, you are making Avalon connections; either MM or ST.

--- Quote Start ---

This interface is also called as System Interconnect Fabric right and is made up of Avalon Bus, right?

--- Quote End ---

Yeah, pretty much.

--- Quote Start ---

These conduits kick in only when the signals are going out of FPGA or if the signals are entering the FPGA right?

--- Quote End ---

Entering or leaving the SOPC system. You could connect them to external signals, or you could loop them back into the SOPC system, eg., control signals from a PIO component might loop back into the system via a different conduit to enable/disable another component.

Now coming to what you said, If I have a PCI bus then, a conduit shows up between the PCI bus external to the FPGA and Avalon interface within the FPGA right?

--- Quote End ---

Yes. All the PCI signals would be marked as conduit signals.

--- Quote Start ---

When conduits show up in Qsys what should I do with them? leave them alone? since they are connected to outside of FPGA.

--- Quote End ---

I would guess you leave them unconnected. I have not used Qsys much yet. I'm not sure why the conduits show up in the GUI. Perhaps someone else can comment.

Cheers,
