Harry Ho a0fd5261ea kc705: cleanup 2021-01-22 11:11:13 +08:00
Harry Ho 7c4eed7a11 kc705: simplify DRTIO master & satellite
* KC705 master: user can no longer choose whether or not the SMA acts as the 2nd DRTIO channel; SFP and SMA now act as the 1st and 2nd channel respectively by default.
* KC705 satellite: user should now use `--sma` to enable using the SMA as the satellite channel; SFP acts as the satellite channel by default.

Harry Ho 9daf77bd58 kc705: add multichannel support on satellite
* Two DRTIO channels (i.e. satellite and repeater) are enabled by default.
* User can choose either the SFP or SMA as the satellite channel (by passing `--drtio-sat sfp` or --drtio-sat sma` to the argparser), and the unchosen would become the repeater channel.

Harry Ho 52afd4ef6b kc705: add GTX multilane support, add multichannel support on master
* One DRTIO master channel is enabled by default.
* User can set the SMA as the 2nd master channel (by passing --drtio-sma to the argparser).
* Multi-channel (i.e. with repeaters) on KC705 satellite is supported but has not been implemented yet.

Robert Jördens ea79ba4622 ttl_serdes: detect edges on short pulses
Edges on pulses shorter than the RTIO period were missed because the
reference sample and the last sample of the serdes word are the same.

This change enables detection of edges on pulses as short as the
serdes UI (and shorter as long as the pulse still hits a serdes sample
aperture).

In any RTIO period, only the leading event corresponding to the first
edge with slope according to sensitivity is registerd. If the channel is
sensitive to both rising and falling edges and if the pulse is contained
within an RTIO period, or if it is sensitive only to one edge slope and
there are multiple pulses in an RTIO period, only the leading event is
seen. Thus this possibility of lost events is still there. Only the
conditions under which loss occurs are reduced.

In testing with the kasli-ptb6 variant, this also improves resource
usage (a couple hundred LUT) and timing (0.1 ns WNS).
