Adrian Costina 83cebe899f daq3: Update projects to the new TPL
Also modified the FIFO ports to have the same widths so that in a
future commit the bypass would be available for cases when the
sampling rate won't be the maximum rate or the number of channels
active will be less than maximum number of channels

Istvan Csomortani 9f58b465ea adaq7980: Add AXI pulse generator to generate the offload trigger 2020-10-21 09:59:26 +03:00
Istvan Csomortani 7732a365b5 Revert "axi_spi_engine: Add pulse_width and pulse_period registers"
This reverts commit 0402ce85e4
and reverts commit 164aa97ec3.

The trigger pulse generation must be handled outside of the
SPI Engine framework.

It is recommanded to be done in system level using a PWM
generator or an external signal.

Laszlo Nagy 4026eaa19b ad9081_fmca_ebz: Fix device clocks termination
The device clocks are AC coupled LVDS lines without external termination.

ad9656:Add reference design for the ad9656 eval board (#494)
Added reference design for the ad9656 evaluation board coupled with the
zcu102 carrier board. The JESD204 communication link that transfers data
from the 4 ADCs to the FPGA has the following paramenters : L=4, M=4, S=1,
F=2, HD=0, N=16, NP=16. The JESD204 line rate is configured to be 2.5GHz.

Sergiu Cuciurean da6d9da4f0 projects: cn0540: coraz7s: Add XADC support
The coraz7s has an Arduino/chipKIT Shield connector with 6 Single-ended
and 8 Differential Analog inputs tied to Xilinx's XADC.
The CN0540 uses the A0-5 pins as single-ended ADC channels to monitor
the differential input, ADC driver, and buffer voltages.

Istvan Csomortani 11822e2824 cn0540/coraz7s: Set and input delay of one spi_clk cycle for the MISO line
Note, the current SCLK to spi_clk ratio is four. That means, the input
delay in the MISO line is 25% of the SCLK period.

If the SCLK to spi_clk ratio is changing, this constraint must be
updated.

Istvan Csomortani dae1de0405 cn0540/bd: Generate a 80MHz spi_clk
Generate a higher frequency of spi_clk using an axi_clkgen. (MMCM)

CAUTION: ad7768-1 is still violating the standard SPI timing,
reducing the timing window significantly for the last bit (or last high
bit).

Sergiu Arpadi 681ddc2e25 axi_gpreg: Add ttcl for clock_mon constraints

is set to 0 and the constraints written in up_clock_mon_constr.xdc
cannot be applied; removed up_clock_mon_constr.xdc from ip core.

Laszlo Nagy 7c523fbf02 jesd204_rx: Reset frame alignment monitor event generator

Laszlo Nagy 0ecf4254ec axi_jesd204_rx: Ignore events if link not enabled
When the link is disabled the events can be ignored.
This is required by the free running event counter that can catch
invalid events during startup cased for example by an invalid link clock.

Laszlo Nagy aa4de79045 jesd204/jesd204_rx: Ignore frame alignment errors if lane is not in DATA phase
If the lane looses synchronization due invalid characters or disparity
error the lane alignment monitor checks random input which results in
irrelevant reporting of frame alignment error.

Laszlo Nagy d825fffd62 jesd204/jesd204_rx: Reset error counter once all lanes synced
If all lanes are synchronized (CGS state machine is in DATA phase) for long
enough therefore the link is also synchronized/DATA phase reset the error
counter since the accumulated values during INIT/CHECK are irrelevant.
These errors are handled by the per-lane CGS state machine.

All errors accumulated during INIT/CHECK phase of CGS are relevant only
if the link is unable to reach the DATA phase.
The link stays in DATA phase unless software resets it,
so all errors accumulated during the DATA phase are relevant.

Laszlo Nagy ee143d80d6 jesd204_rx/jesd204_rx_ctrl: Fix de-glitch mechanism
The previous implementation of the de-glitch only delayed the assertion
of the SYNC phase by 64 clock cycles with the DEGLITCH state but if meanwhile
one of the lanes got into a bad state cgs_ready de-asserted the state machine
continued to go SYNCHRONIZED (DATA) state.
This change extends the required number of consecutive cycles while all lanes
must stay in data phase before moving the link to SYNCHRONIZED state from 8 to 256;
This increases the reliability of link bring-up without needing extra
link restarts from software side.
