Changed
sync_wedgeuse existing synchronizer. This defines a single place where a tech-specific synchronizer can be defined.
Fixed
- Fix FIFO push and pop signals in
stream_registerto observe interface prerequisites. - In
fifo_v3, fix data output when pushing into empty fall-through FIFO. Previously, the data
output of an empty fall-through FIFO with data at its input (andpush_i=1) depended on
pop_i: Whenpop_i=0, old, invalid data were visible at the output (even thoughempty_o=0,
indicating that the data output is valid). Only whenpop_i=1, the data from the input fell
through. One consequence of this bug was thatdata_oof thefall_through_registercould change
whilevalid_o=1, violating the basic stream specification.
