DAC synchronisation in Sayma v2.0

hartytp commented 6 years ago

Proposal for DAC clocking and synchronization in Sayma v2.0:

users supply the RTM with a reference clock (frequency f_ref) via the front panel (FP) SMA this will be the only supported clocking path (until/unless we adopt some fancy WR-type PLL, which can distribute a high-quality clock to the RTM via DRTIO)
users supply the AMC with a RTIO clock (frequency f_rtio) either via FP SMA (master/standalone) or via fibre + CDR (satellite)
in the first instance, the only configuration supported in gateware/firmware (NB this is not a hw limitation) will be f_ref = f_rtio to minimize complexity. In future it won't be too hard to support different configurations, such as f_ref=100MHz f_rtio=125MHz. NB the cost of a really low-noise PLL from Wenzel or similar to generate this clock is small compared with the overall cost of ownership of Sayma
the reference and rtio clocks must be phase locked together (e.g. by locking to a common reference)
the RTM reference clock will be buffered with a low-noise buffer (e.g. ADCLK925) and sent to the AMC via the AMC<->RTM connector, as well as an HMC830. This will be useful for future diagnostics. (Unless you don't think this is worth it @sbourdeauducq)
All clocks and important signals on the AMC + RTM will be accessible via suitable test points, such as UFL connectors!
a HMC830 on the RTM generates the DAC clock at up to 2.4GHz by multiplying the reference clock (NB for integer-N synthesis, the input-output propagation delay is deterministic)
the HMC830 output is buffered (again, ADCLK925 or similar) and fed directly to the DACs. There is a constant propagation delay/phase offset (limited only by drift in PLLs and buffers) between the DAC clocks and the reference/rtio clocks. The is no frequency division here, so there is no non-deterministic phase offset
To synchronize the DACs to the RTIO clock, all that needs to be done is to supply a SYSREF pulse from the AMC FPGA that meets S/H at the DACs (w.r.t. the DAC clock, which can run at up to 2.4 GHz)
In principle, the SYSREF pulse could be generated directly by the FPGA. However, the S/H window for a 2.4GHz DAC clock is something like 200ps, which will be hard to achieve for a variety of reasons: drifts between the phase of the RTIO and reference clock due to the SI5324 (already something like 100ps); FPGA jitter; SI between the two boards; general VT fluctuations in all components; etc
As a result, we opt to put a discrete, low jitter FF on the RTM to retime the SYNC pulse produced by the FPGA. This FF is clocked by the RTM reference clock. This ensures that the FPGA is able to generate a low-jitter SYNC pulse with a fixed phase relationship to the RTM reference clock
since the input timing window for this is close to 8ns, meeting S/H timing is relatively easy (we could nonetheless choose to buffer these signals and route a copy to the RTM FPGA for diagnostics if @sbourdeauducq thinks it's worth it?)
in principle, we could fix the time delay between the FF output and the DAC SYSREF pin by trace length to ensure that S/H timings are always met in HW. However, given how narrow the timing window is, I'd be inclined to add a phase trim to this. The easiest way of achieving this is with a very simple digital delay line placed after the FF, such as http://www.onsemi.com/PowerSolutions/parametrics.do?id=586

Edit: we could consider adding solder jumpers to allow the FF + phase shifter to be bypassed in Sayma v2.0 if anyone wants to have a go at driving SYSREF directly from the FPGA.

Repeat of the same measurement, but with an extra 333us delay added between DAC phase checks. This shows that the odd pattern we see doesn't seem to be dependent on the gaps between phase checks. It really seems that the DAC just gives us a different answer sometimes.

I'm convinced that this is not consistent with SI issues (how could we possibly get that kind of periodicity?). The obvious things I can think of are: (1) we're not doing the phase check correctly (@sbourdeauducq if I post my code this eye, can you do a review of the sync checks please?) (2) it's a hardware issue with the DAC at higher clock frequencies (worth contacting an ADI engineer?).

Either way, I think we need to resolve this before v2.0

@sbourdeauducq I'm pretty sure this is something to do with the way we validate the SYSREF phase. Switching to using one-shot then monitor mode, at 1.2GHz I see things like

@sbourdeauducq as a next step, please could you or @enjoy-digital please try to reproduce this using the 1.2GHz clock and x2 interpolation?

hartytp commented 6 years ago

eye scan in one-shot then monitor mode, reporting let sync_status = read(ad9154_reg::SYNC_CURRERR_L) as u32 + ((0x1 & read(ad9154_reg::SYNC_CURRERR_H) as u32) << 8); now at 2.4GHz dac clock.

sbourdeauducq commented 6 years ago

Will start working on this on Wednesday.

hartytp commented 6 years ago

Thanks @sbourdeauducq ! I'm becoming more convinced that this is either a bug in the AD9154 or us misunderstanding how the synchronization logic works (the documentation is a bit sparse and ambiguous). Trying a different procedure:

init the SYSREF to a calibrated value. For now I'm using 255
put the AD9154 in one-shot then monitor mode and enable the SYSREF machine
sweep the delay line phase while measuring the phase error currerr = currerr_l + ((currerr_h)&0x01) << 8)

Here is an eye scan doing that, taking 10 data points at each delay line phase. Apologies for the ugly printing.

This is using the 1.2 GHz DAC clock, so approx 76 11ps taps per clock cycle.

1G2_eye.txt

The working region extends from 200 to 281 with a nice sharp transition edge and no dead zones in the middle. So that looks good!
I haven't got my head around what those numbers actually mean. Why is the counter value so large? I didn't think the LMFC got that high
the synchronisation doesn't seem to be 100% reliable. Sometimes I get a wall of 500ish numbers in the region where the edge should be. So, I think our process will need to be something like:
- set the delay to the calibrated value
- enable one-shot then monitor mode and arm sync machine
- do an eye scan. if we find a working region where we expect it then check the margins, otherwise rearm the machine and go again

anyway, at least this method gets rid of that odd periodic behaviour

hartytp commented 6 years ago

And, here is a synchronized DAC at 2.4GHz.

eyes2.txt

Working region is 38 taps which is spot on what we expect.

The bad news? It took a few power cycles of the device to produce this. Provisionally, then, it seems that at the higher clock frequencies the sync logic does not always work. But once the device is synchronized it stays synchronized fairly well (will need to do a longer term measurement to make sure) and gives good eye scans.

Next step: see if we can achieve good eye scans on every boot by repeatedly re-arming the sync machine until it works.

Let's see if that actually translates into synchronised RF...

hartytp commented 6 years ago

Detailed setup:

Sayma standalone clocked at 150MHz from a synth (call this ref_clk)
HMC830 PLL produces 2.4GHz dac_clk (deterministic latency w.r.t. ref_clk since output divider not used)
HMC7043 DAC clock outputs in "fundamental mode" i.e. no dividers so still deterministic latency
HMC7043 clocks the FPGA at 150MHz this uses a divider, so gives the 150MHz rtio_clk a random phase w.r.t the ref_clk
FPGA produces a sysref signal at 9.375MHz. This is used to reset the FPGA JESD core
FPGA SYSREF signal output on SMA 0
FPGA SYSREF is retimed using an external FF that's clocked from ref_clk. NB I do not bother to control the phase of the FPGA SYSREF output w.r.t. the ref_clk. I just hope that it meets S/H, which it generally does, but for some restarts this isn't true.
retimed SYSREF passes through a digital delay line
delay is set to ensure that SYSREF meets S/H w.r.t. dac_clk at the DAC pin
The code below is a cleaned up version of the experiment I'm running on the FPGA as a startup Kernel. The idea is that this switches the SAWG on and off at the same time (up to a constant latency) as the SYSREF edges, clearing the phase accumulator for each run of the experiment
the screenshot above was taken with infinte persist on, accross ~10 power cycles of Sayma
- Yellow trace is a DAC output
- Green trace is ref_clk
- blue trace is the phase-shifted SYSREF
We see that the timing between all clocks is fixed (no 416ps indeterminism) indicating that the RF output from Sayma is correctly synchronised with the FPGA-generated SYSREF
additionally, I have verified that the un-retmined FPGA-generated SYSREF is synchronised with local TTL events by running the same experiment and looking at the two FPGA SMA outputs (one of which is SYSREF and one of with is controlled by a kernel). Note that the kernel-controlled TTL is not completely synchronised with the RF because of the way I clock it. If I clocked the FPGA from the ref_clk directly this wouldn't be a problem, but I'd have to mess around with gateware to do that and I don't have time right now

hartytp commented 6 years ago

tl;dr since the above shows that the RF is synchronised with local RTIO events, and we know that DRTIO correctly synchronises RTIO events between devices, I believe that the above is a complete demonstration of board-board synchronisation on sayma

hartytp commented 6 years ago

Looking over a further 10 power cycles of the device, I did see 2 times when it did not correctly synchronize:

sync

Best guess is that this is due to the FPGA SYSREF not meeting S/H at the retiming FF

hartytp commented 6 years ago

Are there any other measurements that people want to see before I disassemble my test setup and we finalize our plans for Sayma v2.0? (@sbourdeauducq @jordens @gkasprow )

sbourdeauducq commented 6 years ago

Hmm I suggest investigating why it sometimes does not synchronize. Can you change the timing of the FPGA output that goes to the FF?

hartytp commented 6 years ago

@sbourdeauducq for the sake of completeness, I redid the clocking on my Sayma. Now:

AMC is clocked at 150MHz using a power splitter to take power from ref_clk and a balun to drive the SYSCLK1 input
I'm now triggering my measurement from the kernel-controlled TTL and looking at the delay between the TTL and the RF output
about 60%-80% of the time (not sure of the exact statistics), the latency is completely deterministic.
However, some times there jumps in the TTL->RF latency. The size of these jumps looks to be 1/600MHz=1.66ns which is the data rate
Given that the jumps are not spaced by 1/2.4GHz, we can conclude that the DAC is reliably synchronising to the SYSREF (the RF is always aligned to a 150MHz edge), but that there is some non-determinism somewhere else. e.g. a bug in my code or in the JESD core

Will post a photo in a sec

hartytp commented 6 years ago

@sbourdeauducq based on the symptoms I'm seeing, I do not believe that this issue can be caused by S/H violations at that FF. I think it can only really be some issue to do with the gateware i.e. a bug in my code or a bug in the JESD core or somewhere in between

hartytp commented 6 years ago

@sbourdeauducq Assuming that you agree that, given the symptoms, this is most likely to be a gateware issue: I think the next step in terms of tracking this down would be a review of my code to make sure that I haven't messed up the clocking / synchronisation.

@sbourdeauducq one thing I did wonder about was the CDC between the reset of the JESD core and the JESD transceiver clock. Right now, the JESD core is clocked from the HMC7043 divider output, but the AMC FPGA fabric is clocked from my external 150MHz reference. Since there is no well-defined phase relationship between these two, I wonder if the CDC can add a cycle or two of non-determinism? That type of issue should be fixed in v2.0 when we have more suitable clocking options.

Anyway, if you do a review of my code and spot anything else you want me to try out then let me know. Otherwise, I'm happy to leave this here for now as I do feel that the point has been proved even if there is still some gateware issue to fix

Not really; >99% of Sayma development time is spent banging one's head on the desk wondering why it sometimes does not work.

hartytp commented 6 years ago

@sbourdeauducq sure. But, I'm trying to triage this. My goal in this issue is to prove that with this hardware the DACs can correctly be synchronised at full speed. Based on the data we have, I believe that is the case (if the DACs weren't picking up the SYSREF edges correctly, the jitter would not be quantized in 1/600MHz steps).

Getting rid of the gateware bugs to make sure that the RTIO clock is synchronized with the RF is a separate issue IMHO. And, it's one that I don't feel qualified to deal with -- I don't understand the JESD core or the overall data flow in the gateware enough to contribute to that.

hartytp commented 6 years ago

Anyway, if you do a review of the code I'm using then you may well see an obvious potential cause of this issue, in which case I'd be more than happy to repeat the tests.

hartytp commented 6 years ago

@sbourdeauducq AFAICT the indeterminism is +-1 cycle of the 600MHz clock, so I think it's likely that it's just the CDC on the JESD core.

sbourdeauducq commented 6 years ago

What CDC are you talking about exactly? JESD204 sync does not care about latency variation on the transceiver lanes, as far as I know.

hartytp commented 6 years ago

okay. Well, as I said I haven't got my head around how all this works.

I mean that the transceivers are clocked from the divided 2.4GHz clock, but the fabric is clocked from the external 150MHz reference and it's not clear to me that there isn't some potential issue there. Anyway, I'll leave it at that now, as someone who knows more about this than me needs to do a code review.

Anyway, we're close!

Here is a trace of 92 restarts via artiq_flash, triggering of the kernel-controlled TTL and looking at the RF phase. Jumps are mainly 3.3ns (2x600MHz clock cycles) but it looks like in one step there was a single slip of the 600MHz clock. sync

hartytp commented 6 years ago

now:

still triggering from the kernel-controlled TTL
blue is the retimed + phase-shifted SYSREF
yellow is the RF
persist across 10 restarts via artiq_flash

We see that the issue is not caused by the sysref moving around (e.g. due to S/H violation at the retiming FF)

Clock relationships here:

dac period = 416ps
lane clock period = 166ps
data period = 1.66ns
byte rate = 1.66ns (lane rate /10 due to 8b10b)
Pclock rate = 6.66ns (4 * byte rate)
frame rate 13.33ns
