Florent Kermarrec 40a8504dd6 phy/kusddrphy: use specific sys4x_dqs clock since we can't ensure initial delay between dq/dqs using odelaye3 on ultrascale...
tap delay can vary from 2.5 to 15ps across PVT

Florent Kermarrec 5977a6fca0 phy/kusddrphy: remove comment on idelaye3 initial delay since fully covered by software 2017-07-10 13:59:24 +02:00
Florent Kermarrec 86b0cc0a56 frontend/bist: restrict lfsr to 32 bit allow bist with large ddram
msbs data are then filled with zeros, but we should fix lfsr generation to avoid this

Florent Kermarrec 062177502b phy: add bitslip module (we need to implement it in logic for Kintex Ultrascale since not provided by ISERDESE3) 2017-02-10 08:59:13 +01:00
Florent Kermarrec 1430cb3d49 phy: add initial Kintex Ultrascale PHY (incomplete)
Input deserializer still missing, need to implement bitslip in logic and use new fifo interface.
Others primitives should be fine.

Florent Kermarrec e7fe539c73 frontend/bist: remove LiteDRAMBISTCheckerScope.
Checker should not be used to investigate errors but only to verify that is already validated still works. (ie we don't want to be able to understand what is going on, just to know if it's working or not). To understand what is going on we will look at signals with LiteScope and eventually trigger on err_count from checker.
