Fixes #807.
 2023-09-03 04:37:59 +00:00
Marcelina Kościelnicka 8c4a15ab92 hdl.mem: lower Memory directly to $mem_v2 RTLIL cell. 
The design decision of using split memory ports in the internal
representation (copied from Yosys) was misguided and caused no end
of misery. Remove any uses of `$memrd`/`$memwr` and lower memories
directly to a combined memory cell, currently the RTLIL one.

Catherine 1826fa83bd Formalize test and documentation workflows using PDM. 2023-07-24 13:46:48 +00:00
Catherine a921261215 build.run: add env= argument to BuildPlan.execute_local(). 
Build scripts are explicitly intended to have overrides that are
done through the use of environment variables, and right now this
would require a very awkward `run_script=False` invocation followed
by copying a bit of code out of the Amaranth codebase, which is
clearly suboptimal.

Adam Greig 45b9730786 Implement RFC 6: CRC Generator 
See amaranth-lang/rfcs#6 and #681.

Catherine 46433268cd docs/changes: update. 2023-06-07 13:50:04 +00:00
Catherine 7d99981d57 Implement RFC 15: Lifting shape-castable objects. 
See amaranth-lang/rfcs#15 and #784.

Note that this RFC breaks the existing syntax for initializing a view
with a new signal. Instances of `View(layout)` *must* be changed to
`Signal(layout)`.
 2023-05-15 19:42:12 +01:00
Catherine a70cfa05cd lib.data: fix incorrect and very misleading example in documentation. 
Found while working on amaranth/rfcs#15. The new code is also robust
in the face of RFC 15 itself (the value returned by Signal will change
but that will save work for the programmer).
 2023-05-15 10:55:44 +01:00
Catherine 68e292c681 lib.data: add reference documentation. 2023-05-12 19:54:47 +01:00

Josuah Demangeon a0307c343d docs: disambiguate Cat(a, b, ...) support for more than 2 arguments

 2023-03-21 14:16:27 +00:00
Catherine 80343d1c4c hdl.ast: warn on fencepost error in Signal(range(x), reset=x). 
Also, relax the language reference inset from "warning" to "note"
since this is no longer something developers have to keep in mind
explicitly.
 2023-03-13 20:38:41 +00:00
Catherine 57612f1dce lib.enum: add Enum wrappers that allow specifying shape. 
See #756 and amaranth-lang/rfcs#3.
 2023-02-28 13:00:41 +00:00
Catherine ef2e9fa809 hdl.ast: Value.matches() with no arguments should return C(1). 
The behavior of the following must be always the same:
- `with m.Switch(v): with m.Case(*pats):`
- `with m.If(v.matches(*pats)):`
