Just one VCC or GND xlconstant will be generated for each width. This
way we can avoid having a lot of xlconstant instances with the same
configuration.
Some FMC boards do utilize more than one transceiver quad but do not
necessarily use all transceivers in a quad. On such board is the
AD9694-500EBZ. Which uses two transceivers each in two adjacent quads.
This board can not be supported by instantiating a util_adxcvr with only 4
lanes. Since those 4 lanes would be packed into the same quad. Instead it
it is necessary to instantiate a util_adxcvr with 6 lanes. 4 lanes for the
first quad and 2 for the second.
To still to be able to connect such a util_adxcvr to a link layer with only
4 lanes allow to specify sparse lane mappings. A sparse mapping can have
less lanes than the util_adxcvr and some lanes will be left unconnected.
For example for the AD9694-500EBZ the lane mapping looks like the following:
ad_xcvrcon util_ad9694_xcvr axi_ad9694_xcvr ad9694_jesd {0 1 4 5} rx_device_clk

Sometimes the output clock of the transceiver should not be used for the
device clock.
E.g. for deterministic latency with no uncertainty the device clock needs
to be sourced directly from a clock or transceiver reference clock input
pin.
Add an option to the ad_xcvrcon command to specify the device clock.
In case the same device clock is used for multiple JESD204 links, e.g. a TX
and a RX link only one reset generator is created.

The standard Makefile output is very noisy and it can be difficult to
filter the interesting information from this noise.
In quiet mode the standard Makefile output will be suppressed and instead a
short human readable description of the current task is shown.
E.g.
> make adv7511.zed
Building axi_clkgen library [library/axi_clkgen/axi_clkgen_ip.log] ... OK
Building axi_hdmi_tx library [library/axi_hdmi_tx/axi_hdmi_tx_ip.log] ... OK
Building axi_i2s_adi library [library/axi_i2s_adi/axi_i2s_adi_ip.log] ... OK
Building axi_spdif_tx library [library/axi_spdif_tx/axi_spdif_tx_ip.log] ... OK
Building util_i2c_mixer library [library/util_i2c_mixer/util_i2c_mixer_ip.log] ... OK
Building adv7511_zed project [projects/adv7511/zed/adv7511_zed_vivado.log] ... OK
Quiet mode is enabled by default since it generates a more human readable
output. It can be disabled by passing VERBOSE=1 to make or setting the
VERBOSE environment variable to 1 before calling make.
E.g.
> make adv7511.zed VERBOSE=1

Currently the individual IP core dependencies are tracked inside the
library Makefile for Xilinx IPs and the project Makefiles only reference
the IP cores.
For Altera on the other hand the individual dependencies are tracked inside
the project Makefile. This leads to a lot of duplicated lists and also
means that the project Makefiles need to be regenerated when one of the IP
cores changes their files.
Change the Altera projects to a similar scheme than the Xilinx projects.
The projects themselves only reference the library as a whole as their
dependency while the library Makefile references the individual source
dependencies.
Since on Altera there is no target that has to be generated create a dummy
target called ".timestamp_altera" who's only purpose is to have a timestamp
that is greater or equal to the timestamp of all of the IP core files. This
means the project Makefile can have a dependency on this file and make sure
that the project will be rebuild if any of the files in the library
changes.
This patch contains quite a bit of churn, but hopefully it reduces the
amount of churn in the future when modifying Altera IP cores.

Currently the IP component dependency in the Makefile system is the Vivado
project file. The project file is only a intermediary product in producing
the IP component definition file.
If building the component definition file fails or the process is aborted
half way through it is possible that the Vivado project file for the IP
component exists, but the IP component definition file does not.
In this case there will be no attempt to build the IP component definition
file when building a project that has a dependency on the IP component.
Building the project will fail in this case.
To avoid this update the Makefile rules so that the IP component definition
file is used as the dependency. In this case the IP component will be
re-build if the component definition file does not exist, even if the
project file exists.

The project top-level Makefile accept the all, clean and clean-all targets
and forward them to their sub-projects.
Create a common Makefile include that can be used to implement this
behavior. The shared Makefile collects all sub-directories that have a
Makefile and then forwards the all, clean and clean-all targets to them.
This is implemented by creating virtual targets for each combination of
sub-project and all, clean, clean-all targets in the form of
"$project/all", ... These virtual sub-targets are then listed as the
prerequisites of the project top-level Makefile targets.
This means there is no longer a need to re-generate top-level Makefiles
when a new project or sub-project is added.
It will also allow to remove a lot of boilerplate code.

The project Makefiles for the Xilinx projects share most of their code. The
only difference is the list of project dependencies.
Create a file that has the common parts and can be included by the project
Makefiles.
This drastically reduces the size of the project Makefiles and also allows
to change the Makefile implementation without having to re-generate all
Makefiles.

To reduce compilation time use default stratagies for synthesis and
implementation. If a project will require custom strategies, enable it
just for that particular project.
This modification will affect both Intel and Xilinx projects.
Vivado sometimes generates semi-valid or invalid warnings and critical warnings.
In the past these messages were silenced, by changing its message severity.
These setups were scattered in multiple scripts. This commit is an attempt
to centralize it and make it more maintainable and easier to review it.
If the ADI_HDL_DIR or ADI_PHDL_DIR are set on Windows platforms, an
invalid TCL character (e.g. backslash) may be used as a file separator,
causing issues with the build / library scripts.
Normalize the paths before using them as global TCL variables.
Some of the standard Quartus components (especially the Merlin cores) generate
quite a few synthesis warnings. Lets assume these are false positives and
disable the warnings.

Add a parameter to the ad_xcvrcon function that allows to provide a mapping
between logical and physical lanes. By default if no lane map is provided
the logial and physical lanes are mapped 1-to-1. If a lane map is provided
logical lane $n is mapped onto physical lane $lane_map[$n].

Let the ad_xcvrcon handle the ADI JESD204 link layer cores. The function
will detect the JESD204 core vendor and connect the appropriate signals
based on it. This means it can still be used with the Xilinx JESD204 core
as well.

When trying to use ad_cpu_interconnect to connect to a AXI interface that
is a outer port of a hierarchy this will fail at the moment as it kind find
the matching clock and reset signals.
Add support for traversing into the hierarchy and find the final target AXI
port inside the hierarchy. Then find the matching clock and reset and
traverse them back the corresponding hierarchy outer ports.

In case of axi_interconnects, when just one slave and master interface is
active, the 'Interconnect Optimization Strategy' is disabled. So this
parameter should be set just if there is more than one slave interface.
Only enable bitstream compression only if both the

Enabling bitstream compression reduces the size of the generated bitstream.
This means on one hand it will consume less storage, which is especially
useful for the BOOT partition of the ADI images where we store BOOT.BIN
files for all supported platforms.
On the other hand a smaller bitstream is faster to load from the storage
medium and it is also faster to program to the FPGA. So it reduces the
overall boot time as well.
The only downside of bitstream compression is that the bitstream size is no
longer constant, but depends on the actual design and resource utilization.
This will not work with bootloaders that expect a fixed size.
When building a bitstream using the tcl scripts bitstream compression can
be disabled by setting the ADI_NO_BITSTREAM_COMPRESSION environment
variable.
Initial tests show a reduction of a round 50% in size for most ADI
projects.

Sometimes the find_bd_objs does not do its job, so need to double check that the interface clock is already connected to the p_clock or not.
Not sure about the cause of this behavior, need more investigation. Issue was found first at KC705 base design.
The scripts generating the projects files typically only work correctly with
one specific version of Vivado. If a incorrect version is used the script
may fail at some point with a cryptic error message or may not fail but
create a bitstream that is not working as expected, e.g. unconnected
signals, etc. This patch adds a version check to adi_project_create that
will error out early on stating that the wrong version of Vivado was used
and which is the right version to use.
By default the required version will be the version that is required by the
common scripts. Individual projects can overwrite the required version by
setting the REQUIRED_VIVADO_VERSION variable to the required version or can
bypass the version check completely by setting the IGNORE_VERSION_CHECK
variable to 1.
Callers of the script can also disable the version check by setting the
ADI_IGNORE_VERSION_CHECK environment variable.

In 2014.2 tool version, the way how a definition file needs to be applied is different
The command "apply_bd_automation" should be used, instead setting property PCW_IMPORT_BOARD_PRESET
In non-project mode (PR design flow), after creating the static design the type of the board is set.
NOTE: the definition file for mitx must be installed accordingly in order to get this work
See link: http://zedboard.org/support/documentation/2056
+ Rewrite the pr_verify process, to improve verification time
+ Update the implementation flow: always the biggest logic will be implemented first, to achieve a better result
therefore force the tool to optimize the first logic with 'ExploreSequentialArea'
+ Make utilization report just from the PR pblock, that's more relevant as the utilization report of the whole fabric
- Change implementation strategy to Performance Explore.
At some projects, this could prevent timing issues, it not
increase the overall implementation time in a dramatic way.
The FMCOMMS1 meets timing on ZED/ZC702 only if the phys_opt_design step
is part of the implmentation flow, with the Explore argument.
"This step performs physical optimizations such as timing-driven
replicaiton of high fanouts nets to improve timing results"
