Florent Kermarrec d12caf1e0c common: add TappedDelayLine to simplify delays on control signals. 2020-10-01 18:29:35 +02:00
Florent Kermarrec a5a4a422dd phy/core: move rd/wrcmdphase and computation to Multiplexer.
rd/wrcmdphases are always computated as (rd/wrphase-1)%nphases so it's not useful
to expose them as PhySettings. rd/wrcmdphases are now directly computated in
Multiplexer and static/dynamic rd/wrphases are supported.
