Each individual link of a multi-link has its own sync signal. The top level
sync port that is created by the ad_xcvrcon function is always a single bit
single though.
This results in only the sync signal of the first link being routed while
others are ignored.
To fix this make sure that for multi-link setups the sync port is a vector
port with the width equal to the number of links.

- refclk and refclk_rst were used for ethernet IDELAY, but are not needed anymore
- muxaddr_out pins overlap with regular GPIOs in the Zed base design. The XADC mux GPIOs can be controlled through that. Cusomters that want to directly control the pins through XADC IP must modify the design
In default strategy we having a few path with small negative slack inside of
the MIG, due to the high UI clock (300MHz).
This new strategy solves this issue.
Add support for specifying a set of parameter value pairs when
instantiating an IP core to the ad_ip_instance command. This has the
convenience of not having to repeatedly call ad_ip_parameter with the name
of the core that got just created for each parameter that needs to be set.
It is also useful for cases where some parameters have mutually exclusive
values and both (or more) have to be set at the same time.
This also slightly speeds things up. Whenever a parameter is changed the
core needs to be updated and post configuration scripts might run. When
setting all parameters at the same time this only happens once instead of
once for each parameter.
For example the following sequence
ad_ip_instance axi_dmac axi_ad9136_dma
ad_ip_parameter axi_ad9136_dma CONFIG.DMA_TYPE_SRC 0
ad_ip_parameter axi_ad9136_dma CONFIG.DMA_TYPE_DEST 1
ad_ip_parameter axi_ad9136_dma CONFIG.DMA_DATA_WIDTH_SRC 64
ad_ip_parameter axi_ad9136_dma CONFIG.DMA_DATA_WIDTH_DEST 256
can now be replaced with
ad_ip_instance axi_dmac axi_ad9136_dma [list \
DMA_TYPE_SRC 0 \
DMA_TYPE_DEST 1 \
DMA_DATA_WIDTH_SRC 64 \
DMA_DATA_WIDTH_DEST 256 \

The loopback on the unused gpio inputs consumes routing resources
while does not gives any value for the software.
Connect these lines to zero instead.
Some projects use the ad_iobuf on IOs that are not bidirectional
producing synthesis warnings.
The change fixes warnings like:
[Synth 8-6104] Input port 'gpio_bd_i' has an internal driver
[Synth 8-6104] Input port 'gpio_status' has an internal driver
- connect unused GPIO inputs to loopback
- connect unconnected inputs to zero
- complete interface for system_wrapper instantiated in all system_top
fixes incomplet portlist WARNING [Synth 8-350]
fixes undriven inputs WARNING [Synth 8-3295]
The change excludes the generated system.v and Xilinx files.
- remove interrupts from system_top
- for all suported carriers:
- remove all interrupt bd pins
- connect to GND all initial unconnected interrupt pins
- update ad_cpu_interrupt procedure to disconnect a interrupt from GND
before connectiong it to another pin.
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.

This change adds the TLAST signal to the AXI streaming interface
of the source side for Intel targets.
Xilinx based designs already have this since the tlast is part of the
interface definition.
In order to make the signal optional and let the tool connect a
default value to the it, the USE_TLAST_SRC/DEST parameter is
added to the configuration UI. This conditions the tlast port on
the interface of the DMAC.
Xilinx handles the optional signals much better so the parameter
is not required there.
There are random timing violations on the A10GX board using the
DAQ3 and DAQ2 projects.
Setting the synthesis/implementation strategy to "HIGH PERFORMANCE
EFFORT" increases the success rate of the timing closure significantly.
In the system top of the FMCOMMS5 projects, there are several GPIO lines, which
can not find in the constraint file, respectively gpio_open_15_15,
gpio_open_44_44 and gpio_45_45.
These are floating GPIO pins, as their names suggest. Delete all these wires and
update IOBUF instances.

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 TX side runs on QPLL, and the RX and RX_OS runs on CPLL by default.
The OUTCLK frequency is the same as the REFCLK.
The main reason of this modification is that the links should come up
without any DPR access, after power up, using the default reference clock
configuration (122.88 MHz).
This way the user do not need to modify the block design, just
set the required rate in system_bd.tcl.
This commit does not contain any functional changes.
Explicitly select MIO 52 and 53 pins to be part of MDIO port.

After the tool version change, this pins where by default connected
as MIO GPIOs.
Explicitly disable the "Transfer Start Synchronisation Support"
since the sync lines are not connected in this project.
If the sync input line (s_axi_user[0] or fifo_wr_sync) are not connected,
Vivado 2017.4.1 no longer connects them to the defaultValue defined
in the axi_dmac ip (1). Instead he uses the defaulValue field defined
in the interface definition which in case of both interfaces is 0;
Loop back the unused GPIO pins, and add all the SPI interface to system

- ad77681evb
- ad7768evb
- ad9739a_fmc

- adrv9739
- fmcadc5
- ad6676evb
- ad9265
- ad5766
- fmcomms5
- m2k
The constraint where added to remove timing problems on the reset path.
The constraint paths do not match anymore. The resets are used in a synchronous
way so we don't need the timing exceptions anyway.

- daq2/kcu105
- fmcadc2
- adrv9371x
- fmcomms11/zc706

By default every base design has a SPI interface (hard or soft). In
case of soft IPs (xilinx), the input registers of the interface by default have
the IOB attribute set to TRUE. If the interface are not used, the tool will
generate a critical warning, stating that IOB registers are not connected to
an IO buffer.
The following constraints are disabling the above setup for every base
design, which using a soft SPI IP.
Set the properties to mirror the hardware configuration so
the Vivado tools can provide warnings if there are any conflicts
between configuration pin settings, such as an IOSTANDARD
on a multi-function configuration pin that conflicts with the
configuration voltage.

https://www.xilinx.com/support/documentation/user_guides/ug570-ultrascale-configuration.pdf
The following base constraints were updated:
- kcu105
- kc705
- vc707
- ac701
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.
The script specifies the OUT_CLK_SEL and SYS_CLK_SEL parameter values as
binary numbers. But the tools will interpret them as decimal number
resulting in the wrong selection for OUT_CLK_SEL. Specify the parameter
values as decimal values to avoid this.
This is not a critical issue since software will overwrite this setting at
system boot-up. But it should be fixed anyway.
