Wanda b36e7e0880 lib.fifo: remove dependency on lib.coding. 2024-04-10 20:50:45 +00:00
Catherine b6f51d269e lib.crc,docs/stdlib/crc: improve consistency with the rest of documentation. 2024-04-10 05:08:05 +00:00
Catherine 1a962cc405 docs: remove all generated WaveDrom diagrams. 2024-04-10 01:30:10 +00:00
Catherine 7dd93bea57 Document RFC 62.
This includes a few minor code changes:
- Removing redundant `lib.memory.Memory.Init = hdl.MemoryData.Init`
  re-export;
- Renaming `FrozenError` to `FrozenMemory` and moving it to `.hdl`;
- Marking `ReadPort` and `WritePort` as `@final`.

Wanda 767d69c703 hdl._mem: implement MemoryData._Row from RFC 62. 2024-04-03 17:15:02 +00:00
Catherine 3c6f46717b lib.wiring: allow reset-less signals in interfaces.
This check was originally added out of abundance of caution, but since
then it was observed that reset-less-ness is purely an implementation
detail (see #1220), and furthermore it interferes with adaptation of
`FIFOInterface`` signals (where `[rw]_data` are reset-less) for RFC 61.

Wanda cd6cbd71ca hdl.{_ast,_dsl}: factor out the pattern normalization logic. 2024-04-03 07:34:09 +00:00
Wanda 09d5540430 hdl._mem: add MemoryData class.
This implements half of RFC 62. The `MemoryData._Row` class will be
implemented later, as a follow-up.

Wanda c4bbcc6f8a hdl._ast: enforce the ShapeCastable.const contract in Const(). 2024-04-02 10:24:34 +00:00
Wanda 1d5de80347 lib.data: fix wrong class name on Struct and Union. 2024-03-27 15:00:09 +00:00
Wanda 6ffafef794 lib.memory: raise an error on mutating already-elaborated memory. 2024-03-25 18:40:20 +00:00
Wanda cd51e02de2 lib.wiring: remove stray references to signature freezing. 2024-03-25 14:15:53 +00:00
Catherine 6ce82848d9 lib.memory: Memory.{r,w}_ports.{read,write}_ports.
The abbreviated form was initially added to match `lib.fifo`, but it
looks very out of place on `lib.memory`, and we may be moving away from
such heavy use of abbreviations anyway.

While technically a breaking change, these attributes have very narrow
usefulness and so this change qualifies as "minor".

Catherine 2333c5f0af lib.memory: expand Memory.Init.__repr__().
Display `shape` and `depth` also. `depth` is redundant although useful
for ease of reading (there are always `depth` elements shown), but
`shape` was just lost.
2024-03-22 23:05:42 +00:00
Catherine fc84b8decf lib.memory: remove Memory.Init.depth.
This attribute is fully redundant with `.__len__()`, and is out of place
on a `list`-like container like `Memory.Init`.

The `.shape` attribute, however, provides a unique function.

Wanda 455a7bc6c8 lib.memory: Allow setting Memory.init.
The `init` property is already mutable, so this adds no actual new
functionality, just convenience.

Amelia Cuss a586df89ad lib.wiring.connect: diagnostic when no connection made.
If a connect() call results in no connections being made, and it's
because there were no outputs specified at all, issue an error.

Amelia Cuss c40cfc9fb5 lib.enum: honor enum.nonmember.
Use _EnumDict._member_names to determine which members to consider.
This way we don't need to redo sunder/dunder checks, and `nonmember`s
(introduced in py3.11) are correctly excluded.

This is a defacto public API, given it remains usable from py3.8
until py3.12 inclusive.  (_member_names changes from a list to a
keys-only dict for performance reasons in py3.11, but they iterate the
same.) In current Python main (i.e. what will most likely be 3.13), a
"member_names" property is added which returns those keys.

Catherine b9c9948038 docs: use :py: role for inline Python code, not :pc:.
I originally picked :pc: as it is short for "python code", but it is
obscure and :py: is not taken, so a much more obvious role can be used
instead. Also, we all typo :pc: as :py: all the time anyway.

Wanda 0da439cce1 hdl._ast: deprecate ValueCastable.lowermethod. 2024-02-13 05:06:06 +00:00
Catherine ace7aea375 lib.wiring: track member source locations.
The source location is set to the place where `In`/`Out` was created.

The source location of the instantiation is tracked but overwritten;
we will need to change the internal structure storing those to be able
to include both.

Fixes #1085.

Wanda 115954b4d9 lib.fifo: add Memory as submodules instead of its ports. [NFC]
This makes the generated netlist very slightly nicer.

Catherine 5dd1223cf8 amaranth.hdl: start all private names with an underscore.
This change completes commit 9dc0617e and makes all the tests pass.
It corresponds with the ongoing langauge reference documentation effort.

Fixes #781.

Adam Greig db7e64960c lib.crc: make module documentation introduction consistent with other stdlib modules. 2024-01-19 08:57:57 +00:00
Wanda 7f76914b74 Implement RFC 17: Remove log2_int.
Reexports of `amaranth.utils` functions are removed from
`amaranth._utils` to avoid a circular import issue (for `deprecated`).
Since this is a private module, this should not be a problem.
