You will find it a big difference from other traditional tools. How a
wire is displayed is not important. You can even turn off the display of
the wires.
The real important thing is which PORTS should be connected. By this
approach, VTC brings you much more efficiency than any other tool does.
For example, as the online demo shown, a project can be done within 3
minutes.
In order to have less line crossing, traditional tool wastes lots of
screen area. User can hardly find where the port is. Sometimes it may be
on different page. So many people do not like such kind of tools.
By the way, you can also rearrange instances or ports in VTC. But it is
in something different style. And the purpose is maybe not concerning to
wires.
