Jean-François Nguyen 496432edaa Implement RFC 30: Component metadata.

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.

Catherine 11ec35d258 lib.wiring: remove unnecessary flipping in Signature.flatten. 2024-03-15 10:35:50 +00:00
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.

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.

Wanda 6ad0d21cc9 Implement RFC 37: Make `Signature` immutable. 
Fixes #995.
 2023-12-11 19:01:32 +00:00
Catherine b9c2404f22 lib.wiring: make values of In and Out be strings "In" and "Out". 
Their `str()` and `repr()` values are already that; and the 0 and 1
don't make sense. The RFC leaves it unspecified.

Catherine 04f906965a lib.wiring: in is_compliant(sig, obj), check that obj is an interface object with that signature. 
Fixes #935.

Catherine a2e87b370e lib.wiring: fix typo in Signature.flatten. 2023-11-27 15:42:24 +00:00
Catherine 74e613b49d lib.wiring: expand flipped object forwarding to respect @property and del. 
Although `@property` is the most common case, any descriptors are now
properly supported.

The special casing of methods goes away as they work by having functions
implement the descriptor protocol. (`__get__` has some special behavior
to make this possible.)

This is some of the most cursed code I have ever written, yet it is
obviously necessary.

William D. Jones abd74ead55 lib.wiring: flip sub-interfaces accessed via FlippedInterface. 2023-11-22 03:07:41 +00:00
Wanda e53d78474f test_lib_wiring: squash UnusedElaboratable warnings. 2023-10-24 20:18:16 +00:00
Wanda 470477a88f lib.wiring: fix Component.signature on subclasses without annotations. 
On Python <3.10, classes without annotations do not get an
`__annotations__` member at all, so the `getattr` on a subclass falls
back to the parent class `__annotations__`, attempting to create
signature members twice.  Fix that by looking at the `__dict__` instead.

Catherine a90bc7b91a lib.wiring: create flipped interface from flipped signature.
