Both the sys_hps.f2sdram_clock and the sys_dma_clk.clk signal are in the
same clock domain. They are both driven by the same clock. And even though
qsys is capable of detecting this it seems qsys interconnect is not able to
infer this and inserts a extra clock domain crossing bridge between the DMA
and the HPS AXI system memory interface.
To avoid this connect the sys_dma_clk.clk to the sys_hps.f2sdram_clock so
that all components are driven by the same qsys clock signal.

Qsys allows to query to query the clock domain that is associated with a
clock input of a peripheral. This allows to automatically detect whether
the different clocks of the DMAC are asynchronous and CDC logic needs to be
inserted or not.
Auto-detection has the advantages that the configuration parameters don't
need to be set manually and the optional configuration will be choose
automatically. There is also less chance of error of leaving the settings
in a wrong configuration when e.g. the clock domains change.
In case the auto-detection should ever fail configuration options that
provide a manual overwrite are added as well.

Currently the DAC FIFO size for the ZC706 DAQ2 project is 16kB. This is
quite a limiting size for practical applications. Increase the size to 1MB
to allow loading larger waveforms.
In this configuration the DAC FIFO will use half of the available BRAM
cells in the FPGA. This still leaves quite a few BRAMs available for
user application logic added to the design. If a user design should run out
of BRAMs nevertheless they can reduce the FIFO size, if not required by the
application, to free up some cells.

If a parameter value is defined as a string binary (e.g. "001001000000"),
it can confuse the tool, and the value may be used as a decimal number.
To prevent this issue and to improve readability converting all the binary
constants into hexadecimal.
Configure the interconnect and offload modules inorder to activate
its interfaces. In the past, these interfaces did not have any
parameter dependencies, so this configuration were not required.
It seems that there are some dependencies between the fir compiler
cores parameters. With the old order of the parameter settings,
the tool throws the following warning:

The input clock frequency of the axi_clkgen was changed from 200 MHz to
100 Mhz. Update the divider settings accordingly to keep the standard
default output frequency of 148.5 MHz.
The incorrect divider settings did not affect operation of the design since
software reprograms them at startup anyway, but changing them avoids the
following warning:
[DRC 23-20] Rule violation (AVAL-46) v7v8_mmcm_fvco_rule1 - The current computed target frequency, FVCO, is out of range for cell i_system_wrapper/system_i/axi_hdmi_clkgen/inst/i_mmcm_drp/i_mmcm. The computed FVCO is 445.455 MHz. The valid FVCO range for speed grade -1 is 600MHz to 1200MHz. The cell attribute values used to compute FVCO are CLKFBOUT_MULT_F = 49.000, CLKIN1_PERIOD = 10.00000, and DIVCLK_DIVIDE = 11 (FVCO = 1000 * CLKFBOUT_MULT_F/(CLKIN1_PERIOD * DIVCLK_DIVIDE)).
This violation may be corrected by:
1. The timer uses timing constraints for clock period or clock frequency that affect CLKIN1 to set cell attribute CLKIN1_PERIOD, over-riding any previous value. This may already be in place and, if so this violation will be resolved once Timing is run. Otherwise, consider modifying timing constraints to adjust the CLKIN1_PERIOD and bring FVCO into the allowed range.
2. In the absence of timing constraints that affect CLKIN1, consider modifying the cell CLKIN1_PERIOD to bring FVCO into the allowed range.
3. If CLKIN1_PERIOD is satisfactory, modify the CLKFBOUT_MULT_F or DIVCLK_DIVIDE cell attributes to bring FVCO into the allowed range.
4. The MMCM configuration may be dynamically modified by use of DRP which is recognized by an ACTIVE signal on DCLK pin.

For the M2K standalone version we run the interface clock at a lower rate
to reduce the power consumption. While this is not necessary on the ZED
board we also run the interface at a lower rate for consistency.
Currently the video DMA on the ZED board uses the interface clock for the
data path as well. This is now too slow to support 1080p@60Hz so move it
over to a faster clock.

At the moment the PS7 is using three PLLs to generate its clocking tree.
One for the DDR, one for the ARM and one for the IO. This allows to run all
components at their respective maximum clock and extract maximum
performance from all components.
With some slight modifications it is possible to trade maximum performance
for a reduction in power consumption by using the same PLL for all three
sets of components and disabling the other two PLLs.
The CPU is now running at 500MHz rather than 666MHz and the DDR memory at
500MHz rather than 533MHz. This reduces power consumption by ~125mW.
This is OK since neither of them is a bottleneck for overall system
performance.
In addition software will downclock the CPU to 250MHz when full performance
is not required.
