Data to DMA/system memory must be presented in widths of multiple of 8 bits,
however this padding is not optimal if is done in the transport layer
since this will affect the DAC/ADC FIFO or offload storage.
This utility block adds or removes padding from sample stream in case the
sample with is not multiple of 8 bits, and can be placed between the DMA
and FIFO/Offload blocks.
In case of multiple SDI (MISO) lanes, the samples arrives in a parallel
fashion. For example in case of 4 MISO line, at the first latching clock
edge 4 bits of a sample will be saved, one bit into each shift register.
The data reorder module reconstruct the incoming samples from the AXI
stream of the offload module.
This commit adds a standalone TDD IP core based on the
existing up_tdd_cntrl module and the up_axi pcore <-> axi bridge.

The laser driver contains the axi_pulse_gen's IP and an additional
register map which controls/monitor the laser driver enable control line
and the over temperature warning line (OTW).
It also contains an interrupt logic, which allows to generate an
interrupt in function of the generated pulse or incoming OTW signal.
The IPs register maps looks as follow:
0x00 - axi_pulse_gen register map
0x80 - axi_laser_driver register map
0x80 - DRIVER_ENABLE
0x84 - DRIVER_OTW
0x88 - EXT_CLK_COUNTER
0xA0 - IRQ_MASK
0xA4 - IRQ_SOURCE
0xA8 - IRQ_PENDING
0xAC - SEQUENCER_CONTROL
0 - SEQUENCER_ENABLE
1 - AUTO_SEQUENCER_ENABLED
0xB0 - SEQUENCER_SYNC_OFFSET
0xB4 - AUTO_SEQUENCE
[ 1: 0] - CHANNEL_SEL_0
[ 5: 4] - CHANNEL_SEL_1
[ 9: 8] - CHANNEL_SEL_2
[13:12] - CHANNEL_SEL_3
0xB8 - MANUAL_SEQUENCE
[ 1: 0] - MANUAL_CHANNEL_SEL
Current interrupt sources scheme is:
- bit 0 : pulse (triggered by the level of the pulse)
- bit 1 : OTW_N enter (triggered by positive edge of the OTW_N)
- bit 2 : OTW_N exit (triggered by the level of the pulse)
Generate a reset signal before the pulse which can be used to reset
various IP's of the data path (eg. pack/cpack). This can help to clear out the
internal buffers and registers of these IP, starting clean at the moment when
the actual pulse arrives.
The sequencer has an auto and a manual mode, and can be set to custom
sequences of the TIA channel selection lines sate.
The sequencer in auto mode is synchronized to the pulse, it will change
its state before a generated pulse which will drive the lasers. The
offset between the sequencer beat and the laser driver pulse can be
modified through an AXI register.
The axi_pulse_gen is a generic PWM generator, which can be configured
through an AXI Memory Mapped interface.
The current register map look like follows:
0x00 - VERSION
0x04 - ID
0x08 - SCRATCH
0x0C - IDENTIFICATION - 0x504c5347 which stands for 'PLSG' in ASCII
0x10 - CONFIGURATION - contains reset and load bits
0x14 - PULSE_PERIOD
0x18 - PULSE_WIDTH
Also update all the other modules, which instantiate the util_pulse_gen.
All projects have been updated to use the new pack/unpack infrastructure.
The old util_cpack and util_upack cores are now unused an can be removed.

The util_cpack2 core is similar to the util_upack core. It packs, or
interleaves, a data from multiple ports into a single data. Ports can
optionally be enabled or disabled.
On the input side the cpack2 core uses a multi-port FIFO interface. There
is a single data write signal (fifo_wr_en) for all ports. But each port can
be individually enabled or disabled using the enable signals.
On the output side the cpack2 core uses a single port FIFO interface. When
data is available on the output interface the data write signal
(packed_fifo_wr_en). Data on the packed_fifo_wr_data signal is only valid
when packed_fifo_wr_en is asserted. At other times the content is
undefined. The cpack2 core offers no back-pressure. If data is not consumed
when it is made available it will be lost.
Data from the input ports is accumulated inside the cpack2 core and if
enough data is available to produce a full output vector the data is
forwarded.
This core is build using the common pack infrastructure. The core that is
specific to the cpack2 core is mainly only responsible for generating the
control signals for the external interfaces.
The core is accompanied by a test bench that verifies correct behavior for
all possible combinations of enable masks.

The util_upack2 core is similar to the util_upack core. It unpacks, or
deinterleaves, a data stream onto multiple ports.
The upack2 core uses a streaming AXI interface for its data source instead
of a FIFO interface like the upack core uses.
On the output side the upack2 core uses a multi-port FIFO interface. There
is a single data request signal (fifo_rd_en) for all ports. But each port
can be individually enabled or disabled using the enable signals.
This modified architecture allows the upack2 core to better generate the
valid and underflow control signals to indicate whether data is available
in a response to a data request.
If fifo_rd_en is asserted and data is available the fifo_rd_valid signal
are asserted in the following clock cycle. The enabled fifo_rd_data ports
will be contain valid data during the same clock cycle as fifo_rd_valid is
asserted. During other clock cycles the output data is undefined. On
disabled ports the data is always undefined.
If no data is available instead the fifo_rd_underflow signal is asserted in
the following clock cycle and the output of all fifo_rd_data ports is
undefined.
This core is build using the common pack infrastructure. The core that is
specific to the upack2 core is mainly only responsible for generating the
control signals for the external interfaces.
The core is accompanied by a test bench that verifies correct behavior for
all possible combinations of enable masks.

For most of the DACs that use JESD204 as the data transport the digital
interface is very similar. They are mainly differentiated by number of
JESD204 lanes, number of converter channels and number of bits per sample.
Currently for each supported converter there exists a converter specific
core which has the converter specific requirements hard-coded.
Introduce a new generic core that has the number of lanes, number of
channels and bits per sample as synthesis-time configurable parameters. It
can be used as a drop-in replacement for the existing converter specific
cores.
This has the advantage of a shared and reduced code base. Code improvements
will automatically be available for all converters and don't have to be
manually ported to each core individually.
It also makes it very easy to introduce support for new converters that
follow the existing schema.
Since the JESD204 framer is now procedurally generated it is also very
easy to support board or application specific requirements where the lane
to converter ratio differs from the default (E.g. use 2 lanes/2 converters
instead of 4 lanes/2 converters).
This new core is primarily based on the existing axi_ad9144.
For the time being the core is not user instantiatable and will only be
used as a based to re-implement the converter specific cores. It will be
extended in the future to allow user instantiation.

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'

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.
