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.
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.
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

Xilinx:
When calling adi_auto_fpga_spec_params in the x_ip.tcl, parameters like
- FPGA_TECHNOLOGY
- FPGA_FAMILY
- SPEED_GRADE
- DEV_PACKAGE
- XCVR_TYPE
- FPGA_VOLTAGE
will be automatically detected and constrained to predefined pairs of values
from adi_xilinx_device_info_env.tcl
The parameters specified in the blobk diagram of the IP(bd.tcl), will be
automatically assign when the IP is added to a block design.
The "adi_auto_assign_device_spec $cellpath" is called in the init
hook (bd.tcl).

Intel:
Info parameters are set in the VALIDATION_CALLBACK according to
adi_intel_device_info_env.tcl
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.
Add support for 8 bit resolution for the transport layer.
Fix parameter BITS_PER_SAMPLES propagation to all the internal modules, in
several cases this variable was hard coded to 16.
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.
