The DDS for each channel was synchronized by the main channel.
One problem with this aporoach is that when a user sets a DDS that
is not from the main channel the sinchronization does not happend.
This behavior is not user friendly in IIO-Oscilloscope or within other
configuration methods.
This commit keeps all channels in sync by triggering the sync on all
channels from each individual channel.
Add support for DDS phase width greather than 16.
The software should read the DDS phase data width register and configure
the DDS init and increment registers accordingly, otherwise the obtained
DDS output frequency will not be the desired one for DDS phase width
different than 16.
DDS_incr = (f_out * 2^(phase_width) * clkratio)/f_if
* Removed the commercial JESD license and put the ADIBSD or GPL v2 like
for other Verilog files

Due to nets being optimized at IP-level during the no-OOC synthesis flow,
constraints related to req_clk (request clock) were not being applied,
causing the design to not meet timing.
The fix considers the synchronous modes, appending the possible resulting
req_clk's names after the synthesis flow.
Due to grounded signals in the DMA_TYPE_SRC != DMA_TYPE_STREAM_AXI config.,
sync_rewind is removed during synthesis, even so, constraints were
trying to be applied to those nets.
To resolve this, sync_rewind block was moved to inside the generate.
Vivado seems to properly suppress "Empty list" warnings when the circuit does not exist because of a generate rule.

* ad_data_in: Add new logic and explanations
* Added parameters IDELAY_TYPE, DELAY_FORMAT, US_DELAY_TYPE to be used
with the IDELAY instances
* Added explanations
* Added option to bypass IDELAY if it's not instantiated, regardless of
the FPGA_TECHNOLOGY parameter
* Determined a part of the logic for EN_VTC (by the UG) but not for all
modes since we don't have use cases for them
* Changed logic when adding ODELAY: now you must set IODELAY_ENABLE = 1
and FPGA_TECHNOLOGY != NONE if you want it
* ad_data_out:
* Updated ODDR parameter
* Fixed issue with ODDR inputs D1, D2: D1 must be with _p and D2 with _n,
according to the Xilinx template
* Removed _ES1 from IODELAY_SIM_DEVICE
* Added ODELAY for UltraScale
* Before, there was no support for UltraScale/+, and the output data
was completely disconnected from the ODDR
* The support for this was requested in this issue, although as of now we don't
have a design that uses it: https://github.com/analogdevicesinc/hdl/issues/917

The SPI Engine cores were named directly inside the script and this
would mean that for multiple SPI Engine instances IPs with the same
name would appear. These updates will introduce the hierarchy name
into the name given to the cores and will therefore allow for
multiple instances of SPI Engine to be added to the same Xilinx
project.
Projects which use spi_engine.tcl will be updated to account for
these changes.
If the sampling clock is lower than dclk*number_of_active_lines*32 the interface should wait for the next adc_ready signal to reset the counter.
The adc_valid_p signal should be set high just for a clock period after the sample was captured.
- Issue introduced by commit 173f4a83d4
- When IODELAY_ENABLE was inserted in axi_adrv9001_if for adrv9001_rx (Xilinx instance),
for Intel instance (intel/adrv9001_rx.v) was omitted and caused a build error for
adrv9001/a10soc

New improvements for the ADI DMAC IP:
1)The capability to manually overwrite the DMA_AXI_ADDR_WIDTH(from GUI or from tcl)
2)DMA_AXI_ADDR_WIDTH attribute is now visible in the Vivado GUI:
-"Auto mode": Automatically calculated by the core tcl files based on the existing attached address segments.
-"Manual mode": Specify the desired dma_width between 32-64 bits.
3)Added two new debug registers that return higher part of the current source/destination address.

* Before, adc_valid was for the previous sample. This said that
at the second rising edge of clk_gate - the first sample is valid,
which is not true
* Alongside with the software issue that will be solved, these fixes
will make the first 2 samples to be with valid data, otherwise the
user has to always keep in mind that the first 2 ones are invalid

When capture length is not programmed the DMA will interrupt the
transfer once it received all the samples he was set in its descriptor,
this case must be handled by resetting the read process and returning
an end of transfer (eot) to the data offload control logic.
Tx path was gated by the FSM also in bypass mode. This must be avoided
since the bypass mode should be independent of the FSM.
Write to bypass fifo only when bypass is enabled
* Added header license for the files that didn't have
* Modified parentheses
* Removed extra spaces at the end of lines
* Fixed parameters list to be each parameter on its line
* Deleted lines after endmodule and consecutive empty lines
* Fixed indentation

On architectures with ports that support cache coherency, the AWCACHE
signal must be set to indicate that transactions are cached. This patch
adds a parameter allowing AWCACHE to be set on an AXI4 destination port.
Deprecate unused parameters.
Change to MEM_SIZE_LOG2, to support only power of 2 storage sizes for
now. However in the future we might want to add support for non pow2
sizes so register map is not changed.
Change transfer length to -1 value to spare logic.
Change FIFO interface to AXIS to have backpressure, this allows the
implementation of data movement logic in the storage unit and let the
FSM handle high level control an synchronization and control the storage
unit through a control interface.
Refactor FSM to have preparation states where slow storages can be
configured and started ahead of the data handling.
Make bypasss FIFO optional since in some cases causes timing failures
due the missing output register of the memory. This can be targeted in
a later commit.
Hook up underflow/overflow to regmap useful in case of external memory
where rate drops due misconfiguration can be detected.
Cleanup for verilator.
Scripting:
Add HBM and DDR external memory support using util_hbm IP
Replace asym_block_ram with util_do_ram IP
This IP replaces the ad_mem_asym module as storage element for the data
offload.
Having standard AXIS interface for data will allow
implementation of storages on UltraRAM.
This IP serves as storage interfacing element for external memories like
HBM or DDR4 which have AXI3 or AXI4 data interfaces.
The core leverages the axi_dmac as building blocks by merging an array of
simplex DMA channels into duplex AXI channels. The core will split the
incoming data from the source AXIS interface to multiple AXI channels,
and in the read phase will merge the multiple AXI channels into a single
AXIS destination interface.
The number of duplex channels is set by syntheses parameter and must be
set with the ratio of AXIS and AXI3/4 interface.
Underflow or Overflow conditions are reported back to the data offload
through the control/status interface.
In case multiple AXI channels are used the source and destination AXIS
interfaces widths must match.
This allows the external synchronization input to be driven from
asynchronous sources like a 1 PPS signal or just signals from different
clock domains in general.
