Define a MIMO_ENABLE parameter for the core, which will insert
and additional de-skew logic to prevent timing issues coming from
the clock skew differences of two or multiple AD9361.
Let the measured transfer length to be cleared at the end of each
transfer, other case in cyclic mode the counter will overflow and will
not present any useful information.
Once xfer_request is set the DMA must accept samples in the same clock
cycle if the fifo_wr_en signal is asserted.
If the req_valid asserts faster than the ID gets synchronized over the
the xfer request asserts without being ready to accept data.
This can lead to overflow assertion when using a FIFO like interface.
This patch addresses the following issue:
In case of transfers with multiple segments, if TLAST asserts on the last
beat of a non-last segment while more descriptors are queued up,
the completions for the queued segments may be missed causing timeout in
processes that wait for transfer completions.
This patch addresses the following issue:
In 2D mode when consecutive partial transfers occur, and the latter is
very short, will interfere with the completion mechanism of the first
transfer leading to uncompleted segments and unreported partial
transfers.
The tb_base.v verilog files does not contain a full module definition,
just some plain test code. In general the files is sourced inside the
test bench main module. As is, defining a timescale in these files will
generate an error, because timescale directive can not be inside a
module.
Delete all the timescale directive from these files.
When only one converter is used there is no need for concatenation and
slicer cores. In that case the TPL will connect to port 0 from the
application layer.
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.
The interrupt controller from Microblaze based projects requires that
all its inputs have attributes which define the sensitivity of the
interrupt line. Other case it defaults to EDGE_RISING which is not the
case for DMAC, leading to incorrect interrupt reporting and handling in
case of such projects.
Out of Context constraints are needed for timing driven synthesis as for
avoiding critical warnings due clock queries.
The memory from the FIFO is inferred in different ways for high clock
speeds. Assume the highest frequency for all projects.
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.
Having a bd.tcl script in every IP is redundant.
adi_ip.tcl:
- add adi_init_bd_tcl - creates a blanch bd.tcl and a
parameters temporary_case_dependencies.mk when compiling an IP.
Its main purpose is to generate the bd.tcl, which will be included in
the IP's file-set.
- adi_auto_fill_bd_tcl will populate the empty bd.tcl based on the
top IP parameters and the presence of these parameters in
auto_set_param_list and auto_set_param_list_overwritable lists.
This task can not be performed by the first described procedure since
the file-set is not yet defined.
adi_xilinx_device_info_enc.tcl:
Split auto_set_param_list_overwritable from auto_set_param_list. As
the name states, some of the parameters are overwritable, this will help
when generating the bd.tcl script.
library.mk:
Include the temporary_case_dependencies.mk if it exists in the
IP root folder. The mentioned *.mk file contains non generic
dependencies for makefiles like targets to clean.
