My top module has 3 signals(clk,rst : Inputs Display : output) I'm trying to instantiate another module which also has the same 3 signals. In my top module i used display as a "reg" for calculation purposes. When i try to instantiate i get an error saying " output or inout port display must be connected to a structural net. So i changed Display to a net. Now i get an error saying "left hand side must be of variable data type" I also tries using a temporary variable to circumvent this problem but keep getting the same error "left hand side must be of variable data type" What do i do..?
