Re: [Iverilog-devel] A question about the VVP file in iverilog

[Stephen W. <st...@ic...>]

The netlist functors in vvp, such as .concat and others, are nodes,
like gates, that take inputs and produce outputs. The .concat is
exactly that: the input is a set of vectors, and the output is a
single concatenated vector. For example:

    concat(2'b01, 2'b11) --> 4'b0111

It's a little bit more complicated than that, but that's the basic principle.
