`axi_demux`: Slave port stalling if the master issues writes depending on reads. about axi HOT 3 CLOSED

So setting MaxMstTrans (defined as "Each slave port can have at most this many transactions in flight.") to at least the value of the number of ARs issued by that master plus one (for the AW) solves the issue?

When I remember correctly, yes setting the value high enought should not trigger the issue.

Found it whilst having a discussion with @thommythomaso about #110. We where not sure how to resolve this natively. The protocol explicitly states that a port should not have a dependency between the channels, which a construct like #110 breaks by design on its master port.

Right, so this not a problem of axi_demux but a limitation of the protocol. It is nonetheless good to know that axi_demux can handle even this case provided MaxMstTrans is set to a sufficiently high value.
