Jean-François Nguyen 496432edaa Implement RFC 30: Component metadata. 
Co-authored-by: Catherine <whitequark@whitequark.org>

Wanda 1d2b9c309e back.rtlil: set read port init to all-x. 
This is an unfortunate necessity needed to fix memory inference regressions
introduced when we switched to using v2 cells. A better approach, compatible
with RFC 54, will need to be figured out for Amaranth 0.6.

Fixes #1011.

Wanda 4b49284ccb hdl._ir: derive DriverConflict from Exception instead of UserWarning. 2024-05-09 02:11:23 +00:00
Wanda 14929b9499 vendor: add AMDPlatform as an alias for XilinxPlatform.

Catherine 994fa81599 Implement RFC 36. 
This feature does not exactly follow the RFC because the RFC as written
is not implementable; the treatment of async resets in `tick()` triggers
had to be changed. In addition, iterating a trigger was made to watch
for missed events, in case the body of the `async for` awaited for too
long.

Catherine f637530093 sim: move Command from core to _pycoro. 
Simulator commands are deprecated and will be removed once RFC 36 is
implemented and released. They are an artifact of the old API.

Catherine eef248a080 pyproject: write XML coverage after running the testsuite. 
This is particularly useful with IDEs that can display coverage in
the editor, e.g. VS Code with the "Coverage Gutters" extension.

Wanda 25c3531e93 vendor.*: fix [io]_domain propagation when creating buffers. 
Closes #1347.
 2024-05-05 04:57:52 +00:00
Wanda 9e82d54302 lib.io: make [io]_domain attributes always present. 
Having conditionally-present attributes causes more problems than it's
worth (see #1347). Just make them contain `None` when irrelevant.

Catherine 3fbed68365 pyproject: use .dev{distance}, not +{node}, for non-release builds. 
At the moment this uses a git URL for pdm-backend because required PDM
functionality (pdm-project/pdm-backend#217) is not released yet.

Wanda 8bf4f77616 sim: use Format.* for VCD output, remove hdl._repr. 
This also changes `decoder` a bit: when an enum is used as a decoder,
it is converted to a `Format.Enum` instead. The original enum is still
stored on the `decoder` attribute, so that it can be propagated
on `Signal.like`.
