When creating a block design targeted for simulation, in the testbench
it is useful to know the parameters of the sub components (e.g DMAC)
Xilinx's way to pass the parameters to the testbench in case of it's AXI
verification IP is through package files. We will do the same for the DMAC.
The package file can be generated from template files (ttcl).
These will be added only to the simulation file set of the project and
won't affect synthesis.
This commit fixes the following warning from the IP packaging flow:
"[IP_Flow 19-801] The last file in file group "Synthesis" should be an HDL file:
"axi_dmac_constr.ttcl". During generation the IP Flow uses the last file to
determine library and other information when generating the top wrapper file.
If possible, please make sure that non-HDL files are located earlier in the list
of files for this file group."
Having the ttcl or other non HDL file at the end of the file group causes issues
when the project preferred language is set to VHDL. Since the synthesis file group
is set to "xilinx_anylanguagesynthesis" the tool tries to guess the type of wrapper
to be generated for that IP based on the last file from the file group.
If the file is non HDL then he defaults to the preferred language (this case VHDL)
Due some issue when the tool tries to create a VHDL wrapper for an IP that has
a Verilog top file with boolean parameters set from the IP packager he fails.
After we reorder the files after each non HDL file addition
he will create a correct Verilog wrapper for it with all parameters
which can be integrated in a VHDL system top file without issues.
Vivado sometimes generates semi-valid or invalid warnings and critical warnings.
In the past these messages were silenced, by changing its message severity.
These setups were scattered in multiple scripts. This commit is an attempt
to centralize it and make it more maintainable and easier to review it.
Currently the name of the newly created IP core is automatically inferred
from the top-level module. This works fine if there is only one top-level
IP. But for an IP core that is a collection of helper modules this fails.

Currently the polarity of the reset signal is always set to negative.
Change this so that the polarity is selected on the suffix of the name. If
it ends with a 'n' or 'N' the polarity will be negative, otherwise it will
be positive.
This allows this function to be used with reset signals that have positive
polarity.

This patch adds a helper function that allows to create multiple ports for
a single set of underlying signals. This is useful when the number of ports
is a configuration parameter. It sort of allows the emulation of port
arrays without having to have on set of input/output signals for each port,
instead the signals are shared by all ports.
The following snippet illustrates how this can for example be used to
generate multiple AXI-Streaming ports from a single set of signals.
<verilog>
module #(
parameter NUM_PORTS = 2
) (
input [NUM_PORTS*32-1:0] data,
input [NUM_PORTS-1:0] valid,
output [NUM_PORTS-1:0] ready,
);
...
endmodule
</verilog>
<tcl>
adi_add_multi_bus 8 "data" "slave" \
"xilinx.com:interface:axis_rtl:1.0" \
"xilinx.com:interface:axis:1.0" \
[list \
{ "data" "TDATA" 32} \
{ "valid" "TVALID" 1} \
{ "ready" "TREADY" 1} \
] \
"NUM_PORTS > {i})"

Commit 2f023437b4 ("adi_ip- remove adi_ip_constraints") changed the
default processing order of IP core constraint files from late to normal.
This is problematic because some IP core constraint files try to access
clocks that are that are generated by different files with the normal
processing order level. These clock may or may not be available to the IP
core constraint file depending on the (random) order in which the files
were processed.
To avoid this issue change the default processing order back to late.

Currently the register map range of a peripheral is hardcoded to 64k. Not
all peripherals need that much space though and reducing the size of the
address can reduce the amount of logic required, both in the interconnect
as well as in the peripheral.
Let adi_ip_properties() infer the size of the register map from the number
of bits of the address when creating the register map.
For backwards compatibility limit the register map size to 64k since
currently peripherals have a address width of 32 bits, event if they use
less.

Typically when a port has a enablement dependency it also should have a
tie-off value to the port is connected to when disabled.
Make it possible to specify this tie-off value when calling
adi_set_ports_dependency().

- Add a process, which automaticaly infer AXI memory mapped
interfaces (adi_ip_infer_mm_interfaces)
- Add missign line breaks to the 'set_propery supported_families'
command
- Fix the deletion of pre-infered memory maps
This patch is a complementary fix of 8b8c37 patch. And fix
all the 'infer interface' issues.
The adi_ip_infer_interfaces process was renamed to
adi_ip_infer_streaming_interfaces. Now the process just do
what its name suggest.
Affected cores were axi_dmac, axi_spdif_rx, axi_spdif_tx, axi_i2s_adi
and axi_usb_fx3. All these cores scripts were updated.
The AXI Memory Map interface is infered in the adi_ip_properties process.
Infer it again in the adi_ip_infer_interfaces brakes the flow,
the tool will not find the cell's address segment, so there will not be
any address space assigned to the AXI interface.
Affected cores were axi_i2s_adi and axi_spdif_tx.
There are a few IP, which is configured by using just the adi_ip_properties_lite
process, therefor the remove_all_bus_interface will be called in the end of that
process, to make sure that all the autogenerated interfaces are deleted during the
IP properties setup.
bd files can be used to automate certain tasks in IP integrator when the
core is instantiated. Add a helper command for adding such files to a core.

Allow to specify the direction of the reset signal for a interface, this is
useful if the core itself generates the reset signal.

The constraints processing order changed to "late" instead of "early", in order for all the clocks in the system to be already created when the IP constraints are applied
In order to be able to use get_clocks in a constraint file the constraint
file needs to run after the constraint file that creates the clock. Allow to
specify the processing order when adding a constraint file to a core.

Add a helper function that allows to add dependencies to IP cores to the
current IP core, this makes it possible to use a module from the other IP
without having to add the file itself to the current core.

This makes the function more flexible and e.g. allows to handle buses from other vendors.

This is unused and unneeded. The AXI interconnect will make sure that a
peripheral only gets requests that are meant for it, there is no need to
check the address in the peripheral itself.
