Sebastien Bourdeauducq fdbf1cc2b2 sayma: rework DAC SYSREF margin validation 
Previous code did not work when delay range was not enough for two rotations.
This removes autocalibration, to be done later. Uses hardcoded value for now.

Sebastien Bourdeauducq 7e5c062c2c firmware: bypass channel divider for HMC7043 DCLK 2019-01-27 11:49:34 +08:00
Sebastien Bourdeauducq f73ffe44f9 firmware: implement DDMTD-based SYSREF/RTIO alignment (draft) 
Mostly works and usually gets the DAC synchronized at 2.4GHz with Urukul across DRTIO.

Needs cleanup and optimization/characterization.

Sebastien Bourdeauducq cb04230f86 sayma: SYSREF setup/hold validation demonstration 
This also removes the standalone target as the ISERDES used
for setup/hold check requires the fine RTIO clock, which in turn
requires a DRTIO transceiver due to the Ultrascale TPWS bug.

Sebastien Bourdeauducq 4941fb3300 sayma: 2.4GHz DAC clocking (4X interpolation) 
* gets another clock divider out of the way
* gets one cycle within range of the HMC7043 analog delay alone
* SYSREF/RTIO alignment removed, to be replaced with DDMTD-based scheme
