This will allow building base test harnesses and place on top of them
existing block designs for simulation purposes.
Test harnesses will contain basic functionality like
- clock and reset generators
- AXI master to aid register access of the cores.
- memory model of the DDR
- interrupt controller
Existing procedures (ad_mem_hp0_interconnect, ad_cpu_interconnect, ... ) will
connect to this harness as they do to a real base design.
To support deterministic latency with non-power of two octets per frame
(F=3,6) the interface width towards the transport layer must be resized
to match integer multiple of frames.
e.g Input datapath width = 4; Output datpath width = 6;
for F=3 one beat contains 2 frames
for F=6 one beat contains 1 frame
The width change is realized with a gearbox.
Due the interface width change the single clock domain core is split
in two clock domains.
- Link clock : lane rate / 40 for input datapath width of 4 octets 8b10b
- lane rate / 20 for input datapath width of 8 octets 8b10b
- lane rate / 66 for input datapath width of 8 octets 64b66b
- Device clock : Link clock * input data path width / output datapath width
Interface to transport layer and SYSREF handling is moved to device clock domain.
The configuration interface reflects the dual clock domain.
If Input and Output datapath width matches, the gearbox is no longer
required, a single clock can be connected to both clocks.
In most of the standalone projects the generic project creation flow is not followed. The project's device
is defined manualy. This fix makes sure that those projects still builds without an issue.
NOTE: In these case we should use adi_project_create directly in system_project.tcl.
By defualt the supported tool chain is Quartus PRO. If you want to
build the project with Quartus Standard, you need to define an environment
variable called QUARTUS_PRO_ISUSED with the value 0. (e.g. export
QUARTUS_PRO_ISUSED=0 )
Note: Not all projects going to build on Quartus Standard, you should
fix the errors if there is any.
There is a major compatibility issue between 2019.1 and 2019.2.
The file system_top.hdf got a different file extention. This will
cause a compilation failer in the end of the build. To save time
and fail earlier, upgrade the version mismatch message to ERROR.
If user still wants to build a branch with different tool version
the variable ADI_IGNORE_VERSION_CHECK should be set to 1.
When channels are not swapped in groups of four but are completely out of order
the common control channel can't be reordered based on the index of the
channel.
Add commands to generate one extra file with resource utilization, in CSV format.
New commands executes only if ADI_GENERATE_UTILIZATION env variable is set.
"prepare_incremental_compile" is defined as a phony target, but is also a
prerequisite of a real target. This will lead to a complete project build
every time make is called.
To fix the issue the functionality of prepare_incremental_compile target
was included in the generic project build target.
Our internal repository was changed from phdl to ghdl. Update the
adi_env.tcl scripts and other scripts, which depends on the $ad_ghdl_dir
variable. This way the tools will see all the internal IPs too.
For all the Xilinx base design, define three global clock nets, which
are saved in the following three global variable: $sys_cpu_clk, $sys_dma_clk
and $sys_iodelay_clk.
These clock nets are connected to different clock sources depending of
the FPGA architecture used on the carrier. In general the following
frequencies are used:
- sys_cpu_clk - 100MHz
- sys_dma_clk - 200MHz or 250Mhz
- sys_iodelay_clk - 200MHz or 500Mhz
Allow the top level files to have parameters.
Pass the parameters from system_project.tcl to the Vivado/Quartus project and
to the block design scripts through ad_project_params variable.
Usage:
1. create a project with a list of parameters:
adi_project_xilinx my_project [list PARAM_A PARAM_A_VALUE PARAM_B PARAM_B_VALUE]
or
adi_project_altera my_project [list PARAM_A PARAM_A_VALUE PARAM_B PARAM_B_VALUE]
2. access the parameter in QSYS or block design through the $ad_project_params variable
e.g
set PARAM_A $ad_project_params(PARAM_A)
set PARAM_B $ad_project_params(PARAM_B)
3. In system_top.v use PARAM_A and PARAM_B as parameters/generics
Look for undefined clocks which do not show up in the timing summary
therefore can lead to silent failures.
If clocks are not defined they are not analyzed during the timing
checks.
Clear the reference checkpoint if the incremental compilation is not
selected through the make option. Other case the scripts will silently
use the reference.dcp checkpoint if that exists.
The scripts are looking for a previous run result, a routed design
checkpoint to use it as a reference during the incremental build flow.
Before clearing the project files, the scrips will save the reference dcp
file in the project folder.
If the reference dcp does not exists the build continues normally.
Proposed workflow:
1. Build your project normally with 'make' or place manually a
reference.dcp file in the Vivado project folder.
2. Do some minor modifications
3. Run the make with the following option:
make MODE=incr
4. Repeat steps 2-3
Using a common IP cache location for all the project will speed up
compile time of common blocks used in base designs. Example a MicroBlaze
core for VCU118 once compiled it will be reused on other projects.
Using a common IP cache will speed up re-compiles of every project in OOC
mode since the cache won't be cleared as with normal compile flow.
In the current form, when connecting a master to the HP ports all
available slave address spaces are mapped to the master (DDR_*, PCIE*, OCM,
QSPI)
Let the PL masters have access only to the DDR_LOW and DDR_HIGH address
spaces to avoid unnecessary resource usage and increase timing margin.
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.

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 \
]

- 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.

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
make[1]: Entering directory 'library/axi_clkgen'
rm -rf *.cache *.data *.xpr *.log component.xml *.jou xgui
*.ip_user_files *.srcs *.hw *.sim .Xil .timestamp_altera
vivado -mode batch -source axi_clkgen_ip.tcl >> axi_clkgen_ip.log 2>&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.
