WebThe problem is not with the connection between the two modules, but the fact the you have an interface port left unconnected. SystemVerilog requires that all interface ports be connected to actual interface instances. The reason for this is that interface ports are just hierarchical references to an interface instance. baul mesaWeb1 Say I have a module foo (in1,in2,out); and module mad1 (in,out); module mad2 (in,out); module mad3 (in,out); While instantiating these modules I want to use the output ( out) of foo as an input to each of the mad modules.
