There is no such requirement. You can connect the input and output
pins to a net in absolutely any order you like.
As far as I know, the only order constraint is that you cannot link a
pin via "net" statement until the component has been loaded.
If you split your HAL config in several files, the "loadrt" statements
are usually spread over different files.
The solution is to break "net" statements as below to keep well
structured config, for an easier reading and maintenance.
file1.hal:
loadrt and2
net mysig and2.0.in0
file2.hal:
loadrt not
net mysig not.0.out
Which is fully equivalent to single HAL config file:
loadrt and2
loadrt not
net mysig and2.0.in0 not.0.out
Of course, this example is not representative of the interest for
multiple files config.
Typical usage is to split the config between hardware related statements
and GUI related statements.
