Qsys conduit

Hi all, 

I've seen that you can't connect a conduit output signal to more than one conduit input signal. 

Is it true?

I think conduits are 1:1 connections only 

 

Theoretically you could connect a conduit with only outputs to multiple conduits containing only inputs, but the qsys gui does not work out whether this is the case, it just takes the safe option

Thanx wombat for your reply. 

So if I have an output PIO from a NIOS, to drive some peripheral modules (for example an "enable" signal), I can't do it in Qsys environment. Am I correct?

you could, but you would have to make a component with 1 conduit input, and as many conduit outputs as you like to distribute the signal, b/c as wombat explained, in QSys, at this time, conduits are point to point.

That's really unfortunate! Thanks, Dalon ;)

Hmmm... I tried inferring an output array in my verilog top-level, and then using a TCL "get_instance_parameter_value" in a for-loop within the hw.tcl to create a parameterizable number of conduits, but QSYS does not seem to accept this. 

 

Is there an example of how to parameterize the number of conduits? In my case, they only drive sinks.
