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.
This commit add support for the dual AD9208-DUAL-EBZ board.
The clocking scheme is different from the other projects.
The device clock (LaneRate/40) is no longer an output of the transceivers (RXOUTCLOCK),
it is received directly from the clockchip SCLKOUT9 output through the REFCLK1.
This is needed for deterministic latency where SYSREF must be sampled
with the device clock by meeting setup and hold time.
The two channels from each converter are merged together and transferred to the DDR with a single DMA.
It has all transceiver parameters set for a 15Gpbs lane rate and uses the QPLL.
REQUIRED HARDWARE CHANGES : The F1 2A fuse must be populated on the FMC
board.
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.
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.
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.
Having a clock assigned manually to the clk output pin of the axi_ad9361
let the Vivado timing engine to not ignore the clock insertion delay when
analyzing paths between clk_0 and the manually created clock that has
the same source (clk_0), resulting in timing failure.
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.
