How to create new pin/port ?

trying to add a connection from the top level down thru several levels.

So its a matter of walking down the hierarchy and - add a port to module "foo" - add the pin to its cell "bar"

I see the functions $cell->new_pin $module->new_port

but I am not sure how to create the pin/port data structures that I would pass to these functions?

And/or is there a bunch of example code I should be looking at, from which I could glean this info? (I'm very willing to try to teach myself)

thanks, Mike

In the tar.gz file, see the t/44_create.t test. The arguments are the same as the accessor names specified under each Verilog::Netlist::{object} manpage.

    my $moda = $nl->new_module (name=>'a', @fl);
    {
        my $x = $moda->new_port (name=>'x', @fl, direction=>'input',  data_type=>'[2:0]',);
        my $y = $moda->new_port (name=>'y', @fl, direction=>'output', data_type=>'[2:0]',);
        my $b = $moda->new_cell (name=>'i_b', submodname=>'b', @fl);
        {
            $b->new_pin(name=>'z', portname=>'z', pinnamed=>1, netname=>'x', @fl);
            $b->new_pin(name=>'w', portname=>'w', pinnamed=>1, netname=>'y', @fl);
        }
    }
