Adrian Costina c32b4b02f3 sync_bits: Change I/O names of wires "in" and "out" for VHDL users 2019-04-23 18:03:23 +03:00
Lars-Peter Clausen d72fac4b1e Add missing timescale annotations
For consistent simulation behavior it is recommended to annotate all source
files with a timescale. Add it to those where it is currently missing.

Lars-Peter Clausen aba62d96c9 util_cdc: Add multi-bit data synchronization module
The sync_data module can be used to continuously transfer multi-bit signals
like status signals safely from the source to the destination clock
domain. A transfer takes 2 source and 2 destination clock cycles. It is not
guaranteed that all transitions on the source side will be visible on the
target side if the signal is changing faster than this. Logic using this
block should be aware of it. The primary intention is for it to be used for
slowly changing status signals.
