Having the same name for dac and adc TPLs creates conflict in the
address segment naming having random names associated to the segments.
This causes difficulties during scripting of the project in test bench
mode.
The value of the HDL parameter NUM_OF_SDI can be read out from the
register at address 0x0C. The same register contains the value of the
DATA_WIDTH.
The register has the following bit layout:
[15: 0] DATA_WIDTH
[23:16] NUM_OF_SDI
[31:24] 8'b0
Forward the offload's sync_id to the register map, by defining an
additional AXI stream interface between the offload and axi_spi_engine.
The last sync_id of the offload module can read out from the
register 0x00C4. It also can generate and interrupt if the irq mask is
configured accordingly.
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.
The external synchronization signal should be synchronous with the
dac clock. Synchronization will be done on the rising edge of the signal.
The control bit is self clearing. Status bit shows that the synchronization
is armed but the synchronization signal has not yet been received
Added EXT_SYNC parameter to be able to keep the dac_sync original
behavior
The external synchronization signal should be synchronous with the
adc clock. Synchronization will be done on the rising edge of the signal.
The control bit is self clearing. Status bit shows that the synchronization
is armed but the synchronization signal has not yet been received. While
the synchronization mechanism is armed, the adc_rst output signal is set
The current format should allow for the SYSREF signal to be used as
synchronous capture start, but will need to be disabled before the
synchronization mechanism is armed
The commit 9ab88f1200 introduced a new
feature for the execution module, which provides the possibility to
delay the SDI line latch with one or more core clock cycle. Unfortunatly
the implementation was not correct and the SDI line was latched at the
wrong time.
This patch fix the aligment of the shift register and the SDI_DELAY parameter,
to latch the SDI line of the physical interface at the right time.
Improve the description of the feature.
In some cases, the Vivado version can contain other characters than just
numbers. One such example is after applying the patch of AR# 71948,
which makes `version -short` return something like `2018.3_AR71948`.
This patch changes the version check to ignore anything after the first
two components of the version.
Add definition for new ultrascale device packages.
The package information is used by software for xcvr calibration.
At the moment, the factors that are influencing the calibration for the new
packages are not clear.
The previous mechanism was "probing" the DMAs for valid data. Better said,
each interpolation channel enabled it's DMA until a valid data was received,
then it disabled the DMA read and waited for the adjacent channel(DMA) to
receive a valid data. Only when for both channels had valid data on the
DMAs interfaces was the transmission started. This added an undesired and
redundant complexity to the interpolation channels. Furthermore, for continuous
transmission, using the above mechanism lead to a fixed phase(sample)
shift between the two channels at each start.
By using the streaming mechanism the interface is simplified and the
above problems are solved.
For Intel projects:
In cases where the clock of source synchronous interface is not routed
through a clock capable pin the DPA receive mode can't be used. Instead
the clock will be routed through a clock buffer from an IO to the clock
tree and from there to the IOPLL.
implemented mux for temp reading either from internal or external
source; updated regmap; added param to identify source for temp
information; updated tacho measurements; added AVG_POW param used
for tacho measuremet average useful for simulations; defaults for
tacho measurements changed to params and added registers; added
prescaler for fsm control, FSM updated; changed register write
process; connected INTERNAL_SYSMONE to regmap, value can now be
read by software;
parameters with same names were duplicated with transceiver specific
names due different default values.
This does not scales very well.
Use same name for the parameters as for other parameters and do the
default value handling in the IP configuration layer.
