Catherine d28d15761d vendor: LatticeICE40Platform→SiliconBluePlatform. 
Devices originally designed by SiliconBlue have one set of primitives,
and devices originally designed by AT&T, Alcatel-Lucent, or Lattice
have a different set of primitives. This is the first step in merging
the non-SiliconBlue Lattice platforms into one.

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`.

Catherine d94c97981a back.rtlil: implement remaining format specifiers. 
This requires a Yosys version from git. The requirement should be bumped
to a proper release before Amaranth 0.5.

Catherine 967dabc2fe docs/{guide,reference}: clarify semantics of a.any() vs a.bool(). 2024-04-03 13:29:19 +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.

implemented later, as a follow-up.

Catherine f261071f7c docs/guide: clarify section on IOBufferInstance. 
There is no reason to assign names to `IOBufferInstance` submodules
because it's ignored anyways.
 2024-03-26 23:21:29 +00:00
Catherine 738d8b7764 hdl: deprecate {Const,Signal}.{width,signed} accessors. 
These accessors used to be necessary (in addition to `.shape()`) while
the AST nodes were mutable. However, after commit 2bf1b4da that made
AST nodes immutable, there is no technical requirement to keep them
around. Additionally:

- `len(value)` is shorter than `value.width` and works with any `value`
- `value.shape().signed` is longer than `value.signed` but works with
  any `value`
 2024-03-26 22:56:17 +00:00
Wanda 0c041f2602 hdl._ir: rename Instance.named_ports to Instance.ports. 
Made possible by the new port propagation code freeing up the name.

Thomas Watson fa2adbef84 hdl.dsl: use private names for FSM ongoing signals 2024-03-25 19:15:24 +00:00
Thomas Watson c7f719ab93 hdl.ast: allow Signals to be privately named using name="" 
* Given a private name `$\d+` in RTLIL (as they are not named in the IR)

* Not automatically added to VCD files (as they are not named in the IR)

* Cannot be traced to a VCD (as they have no name to put in the file)

* Cannot be used with an unnamed top-level port (as there is no name)
