Lars-Peter Clausen 610cc3affa m2k: standalone: Disable DMA debug registers
The debug register logic for the DMA take up a fair amount of resources.
Disabling them frees up space in the FPGA and also helps a bit with power.
Since those registers are mainly useful in development and not so much in
production the change shouldn't have any visible external effects.

It is possible to re-enable the debug registers by setting DEBUG_BUILD=1.

Lars-Peter Clausen 77b453ac0d axi_dmac: Make debug register optional
The debug registers are useful during development but are rarely used in a
production design. Add a option that allows to disable them, this reduces
the resource utilization of the DMAC.

Lars-Peter Clausen c9f863f189 m2k: standalone: Set static switching activity for the reset signals
The global reset signals are only asserted for a short moment during system
startup and deasserted during normal operation, which is the case we care
about for power analysis. Giving them a static switching probability
indicating that they are always de-asserted will yield better results for
power analysis.

Lars-Peter Clausen b206f8f37a m2k: Disable AD9963 core RX datapath again
The RX datapath has a lot of things (IQ correction, DC filter, ...) that
take up a lot of space which are all not really needed in this project. So
disable the RX datapath.

It was previously enabled because the ad9963 core did not perform
sign-extension on the ADC data signal when the datapath was disabled. But
this has now been addressed.

Lars-Peter Clausen a0e30a2211 util_axis_fifo: Improve clock gating of registers and BRAM
Currently the BRAM and data registers in the util_axis_data are ungated
when the FIFO is ready to receive data. This good for high-performance
since it reduces the number of control signals. But it is bad from a power
point of view since it causes additional reads and writes.

Change the core gate the BRAM and data register if either the consumer is
not ready to accept data or the producer has no data to offer.

Lars-Peter Clausen 45f87b46c2 ad_lvds_in: Use "SAME_EDGE" mode
Currently the IDDRs are configured in SAME_EDGE_PIPELINED mode, but then
the negative data is delayed by an additional clock cycle. This is the same
behaviour as using the IDDR in SAME_EDGE mode.

Switching to SAME_EDGE mode removes extra pipelining registers while
maintaining the same behaviour.

Lars-Peter Clausen c1ba57f808 m2k: Rework clocking domains
At the moment the register map fabric and DMA system memory side are
clocked by the 100MHz sys_cpu_clk. While this works fine that is a lot
faster than the clock has to run. There are only a few 100 register map
accesses per seconds at most and they are not on timing critical paths. The
penalty from clocking them at a lower rate is negligible for the overall
system performance.

The maximum clock rate for the DMAs is determined by the throughput
requirements. This is 200 Mbytes/s for the logic analyzer, pattern
generator and each of the DAC DMAs and 400 Mbytes/s for the ADC DMA.

The DMA datapath width is 64-bit so the required clock rates are 25MHz and
50MHz respectively. Some headroom is required to accommodate for occasional
bubble cycles on the data bus and the difference in reference clocks for
the converter and processing system.

The sys_cpu_clk is reduced to 27.8MHz which is fast enough for all but the
ADC DMA. For the ADC DMA a new clock domain running at 55.6 MHz is
introduced.

Lars-Peter Clausen 2eaf931e07 m2k: Replace logic analyzer MMCM
The MMCM generating the logic analyzer clock unfortunately consumes a
disproportionately large amount of power compared to the rest of the
design.

Replace it by sourcing the logic analyzer clock from one of the Zynq FCLKs.
The IO PLL is running anyway so the power requirement is much lower.

For the time being this means we loose the ability to source the clock from
an external pin. But that feature is not supported by software at the
moment anyway. We'll bring it eventually when required.

This changes reduces power consumption by roughly 100mW.

Lars-Peter Clausen 71469490c6 Add a helper module to combine a AXI read-only and a AXI write-only interface into a read-write interface
The read and write interfaces of a AXI bus are independent other than that
they use the same clock. Yet when connecting a single read-only and a
single write-only interface to a Xilinx AXI interconnect it instantiates
arbitration logic between the two interfaces. This is dead logic and
unnecessarily utilizes the FPGAs resources.

Introduce a new helper module that takes a read-only and a write-only AXI
interface and combines them into a single read-write interface. The only
restriction here is that all three interfaces need to use the same clock.

This module is useful for systems which feature a read DMA and a write DMA.
