QSYS - Send data to all slaves at the same time

Hi,

I wonder if it is possible to somehow create a QSys design that has one master (in this case a time provider) that sends the timing information to all connected slaves at the same time (say clock edge).

I think, I cannot use Avalon Master/Slave or AXI Master/Slave architectures because they only support dedicated slave addressing and qsys does not allow 2 or more slaves to share the same address.

I tried to internally (-> inside QSys) connect cunduits of the components, but I'm only able to directly connect two components.

My current workaraound is to connect all components via conduits that i route outside the QSys system and connect them in the top level bdf file. I would like to get rid of this top level routing if possible.

Any ideas or recommendations?

Regards,

Maik

    I'd suggest sending the timing signal using ST-source, You can copy/split this over multiple receiving ST-sinks

    With your hint in mind, I searched through the Qsys component library and found the Avalon-ST splitter component. That looks quite promising. Thank you!
