Created a virtual clock to constrain cnv_en.
Given that the cnv_en should be asserted only once per 8 clock
cycles and only the rise edge is of interest, we can constrain
the path as multicycle path.
Because the inferface signals which pass through the eval board's
Arduino connector are connected to level shifters the design
will not work at the maximum clk frequency of 48MHz. The maximum
tested frequency is 24MHz.
Address size and memory ranges are automatically computed by the
external storage interfacing IP (util_hbm) based on the storage size and
base address so this parameter is redundant.
The internal bypass FIFO has poor timing performance,
when using HBM data can be passed always through the external memory
without storage length constraints, so no need for the internal bypass FIFO.
Make the storage type over writable so it can be set specifically
to carriers.
Address width of external memory AXI master is calculated in the
interfacing core (util_hbm) so that parameters is removed.
The HBM interfacing core requires a 450MHz clock, make it part of the
base design.
The clock can't be obtained from the DDR controller so a clock wizard is
used instead.
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

There are no external termination resistors on the VCU118 and VCU128 for
the SGMII clock lines.
The board files of the VCU118 enables them, but this was not reflected in the
constraint files.
For VCU128 the clocking is similar, even if diff terms are not set in the
board files we should have a consistent approach with the VCU118.

In some cases (GTX2) the transceiver may gate the out_clk when it is in
reset or misconfigured. This will stop the clock generators from getting
a clock prior removing the reset of the XCVR. The XCVR has a requirement
of running user clock while removing the reset. The correct sequence must be :
Enable device clocks (user clock)
Remove the reset from the XCVR

- allow specifying the name of Axi Lite interface from the peripheral were to connect the control bus
- some DDR controllers have an Axi Lite control interface, this creates
a second address segment which causes issues, differentiate the memory
segment from control registers segment

Occasionally with zed, the implementation failed at the placement stage where
the tool could not fit the logic cells inside a single clock region,
constraint required by the usage of regional clock buffers.
This commit allows the usage of the global clock buffers which help the tool
in such cases and allow a larger application logic to be implemented in fabric.

For CMOS case, lane rates are so low that reference clock of the source
synchronous interface can be routed on non-clock routes. The delays on
the clock line are adjusted by the digital interface tuning controlled
through software.
Lock down clock buffers on Rx and Tx interfaces, this avoids suboptimal
placement which causes large skew between clocks at the serdes pins.
1. Reduce max allowed skew between source synchronous clocks that can
occur due PCB differences. 250ps represents a difference more than an
inch.
2. In order to reduce skew between source synchronous clock and the
divided clock instruct the tool to use a common clock root for them.
The default address space for a new bridge is 256 Kbytes. Add an
avl_address_width attribute to the ad_cpu_interoconnect porecess to
define other address space sizes if needed.
The avl_peripheral_mm_bridge will have an 128 Kbyte address space from
address 0x0000.
Modified the project such that there is only one data path for the ADC data: deleted one of the JESD tpl instances, one of the cpack instances and one of the dma instances.

This commit adds a new synthesis option to the design, that controls
whether an internal clock domain crossing will be generated. Disabling
this option allows you to use a synchronization signal that is
synchronized to the write clock domain externally, and possibly shared
between multiple devices.
The default value retains the old behavior.

The derived clocks of the zynqmp core are not calculated correctly due
rounding issues, instead of 100MHz the value of 99999001 is received
causing warnings during system validation.
This can be fixed/worked around with the proper reference clock
definition.
The 2020.1 Xilinx tools have a different tcl procedures to build the boot.bin
file.
This commit updates the adi_make tcl flow for the new tools. The new
process is not backwards compatible with tools older than 2020 version.
In order to workaround optimization issues hit in Vivado 2020.2,
set ADI_USE_OOC_SYTHESIS variable by default to 1. This will build
projects in Out Of Context mode.
Projects can be build in Project Mode by exporting ADI_USE_OOC_SYTHESIS=n.

- update default vivado version from 2020.1 to 2020.2
- add conditions to apply specific contraints only in Out Of Context mode.
- update DDR controler parameters for vcu118 and kcu105 dev boards

The goal of this commit is to make sure there isn't any significance to
the order in which parameters of ad_connect are specified.
As an example, previously you could only `ad_connect target VCC`, while
`ad_connect VCC target` would fail.
Note: This code intentionally ignores bd_{,intf_}ports, because
these can all be treated as bd_pins.

This commit fixes the 16.5Gbps lane rate case where the link drops
