These parameters must be overwritten when the link is at 15Gbps.
The parameters have a GTY4_ prefix since the same parameters are shared
between GTY4 and GTH4 having different default values.
Fix library makefiles dep list using generic vendor info reg
Combine adi_int_bd_tcl with adi_auto_fill_bd_tcl procedure.
This change will simplify the process of generating makefiles for each library.
Removing the bd.tcl script from the adi_ip_files list will remove it from the
make dependency list.
Common basic steps:
- Include/create infrastructure:
* Intel:
- require quartus::device package
- set_module_property VALIDATION_CALLBACK info_param_validate
* Xilinx
- add bd.tcl, containing init{} procedure. The init procedure will be
called when the IP will be instantiated into the block design.
- add to the xilinx_blockdiagram file group the bd.tcl and common_bd.tcl
- create GUI files
- add parameters in *_ip.tcl and *_hw.tcl (adi_add_auto_fpga_spec_params)
- add/propagate the info parameters through the IP verilog files

Fix the following warning:
WARNING: [Synth 8-2611] redeclaration of ANSI port up_es_reset is not allowed
Also make sure, that in all configurations, the register has a diver.
Expose the TX configurable driver ports, more specifically the
TX_DIFFCTRL, TX_POSTCURSORE and TX_PRECURSORE for software. This
provides a soft tunning capability of the transmit side of the
transceivers, in cases where the insertion loss of the channel is too
high or low, comparing to the default value supported by the default
configuration of the GTs.
You can find information about these configuration ports under the
section called 'TX Configurable Driver' in the GT transceivers user
guide. (UG476, UG576)
This commit does not contain any functional modification.
Because the wizard generates the attributes in binary, we should use
binary mode too, so we can compare different configurations more easily.
The Xilinx's reset interface expect that every reset have an associated
interface and clock signal. The tool will try to find its clock and interface,
and automatically associated clock signal to it.
The PLL resets are individual asynchronous resets. To simplify the design
and avoid invalid critical warnings all the reset interface inference
for the PLL resets were removed.
For a proper reset synchronization, the asynchronous reset signal should
be connected to the reset pins of the two synchronizer flop, and the
data input of the first flop should be connected to VCC.
In the first stage we're synchronizing just the reset de-assertion, avoiding
the scenario when different parts of the design are reseting at different time,
causing unwanted behaviours.
In the second stage we're synchronizing the reset assertion.
The module expects an ACTIVE_HIGH input reset signal, and provides an ACTIVE_LOW
(rstn) and an ACTIVE_HIGH (rst) synchronized reset output signal.
Fix the read side of the CDC data FIFO. The read address generation did not
function correctly.
Redesign the read side of the FIFO, and make sure that it becomes empty after
the DMA transfer ends; and never get stock in a cyclic mode.
The dac_last signal is not used anywhere in the module. Remove it and its
synchronization registers.
Fixes the following warnings:
[Synth 8-6014] Unused sequential element dac_dlast_reg was removed. ["axi_dacfifo_rd.v":372]
[Synth 8-6014] Unused sequential element dac_dlast_m1_reg was removed. ["axi_dacfifo_rd.v":373]
[Synth 8-6014] Unused sequential element dac_dlast_m2_reg was removed. ["axi_dacfifo_rd.v":374]

Commit bfc8ec28c3 ("util_axis_fifo: instantiate block ram in async mode")
added the read-enable (reb) signal to the ad_mem block.
It didn't update the ad_mem instance in axi_dacfifo_address_buffer.v. This
results in the read-enable of the address_buffer being tied to 0.
Fix this by connecting the same signal that increments the read address.

Some designs choose to swap the positive and negative side of the of the
JESD204 lanes. One reason for this would be because it can simplify the
PCB layout. The polarity is in most cases also only applied to a subset of
the used lanes.
Add support for this to the util_adxcvr module. This done by adding new
parameter to the modules that allows to specify a per lane polarity
inversion. Each bit in the parameter corresponds to one lane. If the bit is
set the polarity is inverted for his lane. E.g. setting the parameter to
0xc will invert the 3rd and 4th lane.
The setting is forwarded to the Xilinx transceiver for the corresponding
lane.
