Hi,
in an old project I have to maintain, I have many .bdf files where *.tdf modules are inserted as a "Symbol as block" (see attached picture).
I wonder if there is some documentation about these kind of *.bdf files. It is not obvious for me which signals are connected to each other. I had to look into the netlist viewer to confirm the interconnections between the symbols "_decode" and "_counter". I think in a *.bdf file the signalrouting should be more obvious.
Are the interconnections set automatically when the port names of two blocks are the same? E.g. the _win signals are the output of one block and the input of the other. Is there a rule that these signals are connected automatically?
Maybe somebody can explain a little bit what the use of these "Symbols as block" is because to me it is very confusing.
Thank you,
Maik

Hi Maik,
I'm not so familiar with this kind of connections, but I think the connection is done by name. The two additional conduit boxes are required, because the name different between the block and the bus. ( block "_TX", conduit "_TX_DELAYED")
you can find more info's under :

search for "conduit" in the document.
Kind regards
