If this option is defined, there will be a direct interface to the b2r
and r2b interface. The structs will be flattened out to wires for legacy
reasons.
This closes#3.
Up to this point, interrupt outputs are generated and intr, enable,
mask, haltenable, and haltmask are supported. stick, stikcybit and the
different types of interrupts are not yet supported.
This commit also removes the option to turn off santiy checking. This is
a bad idea anyway...
This adds initial support for a dynamic bus-protocol to internal
register logic SHIM. The chosen default protocol at this point is AMBA 3
AHB Lite and the logic is still empty.
-> TODO: Adding the widget instantiation showed that it is required
to have a better interface to parametrize ports & signals in the
YAML. At this point, only a limited set of variables are supported.
Furthermore, all remaining Verilator compilation issues in the field are
resolved. Those were mostly related to non-declared wires and wrongly named
wires.
This commit only adds package supports for addrmaps. It should be
relatively easy to extend this for regfiles in a future commit.
Furthermore, this commit adds support to _disable_ enums.
All components (e.g., fields, registers, addrmaps) are now children
of a common class Component. This common class has certain common
methods such as get_ports(), get_rtl(), or create_logger().
The AddrMap is now prepared to support alias registers by saving the
registers in a dictionary. That way, registers can easily be accessed
once an alias to a register is found. Furthermore, the addrmap template
is now also loaded from a YAML file. Lastly, the first preparements to
insert ports into the addrmap module are made.
For templates, the indents do not need to be added anymore to the
template. Now, a seperate method will automatically indent the RTL
based on simple rules (e.g., increment indent if `begin` is found).
The CLI also supports settings for the tabs (i.e., real tabs or spaces
and the tab width).
A lot of functionality from the __init__() method of the field class
got reorganized. More logic will be reorganized in the future.
This mechanism has custom coloring, support to dump in file and
on the commandline and support to turn either or both off. cli/cli.py
provies a function that can be called in each module to instantiate
a logger for that module.
This wrapper lives in a seperate module and class so that possible
processing of arguments can be done before the config dictionary
gets passed to the compiler.
