For consistent simulation behavior it is recommended to annotate all source
files with a timescale. Add it to those where it is currently missing.

Some parts of the util_cdc library rely on dead logic elimination to remove
unused logic. Unfortunately with newer Vivado versions this results in
warnings about unused sequential elements being removed. Like:
WARNING: [Synth 8-6014] Unused sequential element cdc_sync_stage1_reg was removed.
To avoid this encase the logic in generate blocks that makes sure they are
not generated when not needed.

The event synchronizer can be used to safely transfer 1-bit 1-clock cycle
event signals from one clock domain to another.
For each event recorded in the source domain it is guaranteed that a event
will be generated in the target domain at a later point in time. It is
possible though that multiple events in the source domain will be coalesced
into a single event in the target domain if events are generated faster
than they can be transferred.
