Hi Mateusz,
After a quick view, just few things regarding coding styles.

How about aligning all above with same no. of tabs?

These macros seems little bit odd in our common practice,
perhaps these are making code harder to read below.

Using one line per parent isn't increasing length of file unnecessarily?

Any reason/hidden advantage for using a separate of ALIAS,
instead of using MUX_A/GATE_A ?

Why this special comment/treatment for PLLs :) ?
Others below doesn't get such treatment.
