Wanda 0e6d802de4 Implement RFC 58: Core support for ValueCastable formatting. 2024-04-03 19:59:19 +00:00
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 0e4c2de725 Implement RFC 59: Get rid of upwards propagation of clock domains 2024-04-02 17:00:42 +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 86d14f584e Implement RFC 39: Change semantics of no-argument m.Case(). 2024-01-13 22:33:54 +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.

Jaro Habiger c00e770f01 build.run: deprecate run_script argument in BuildPlan.execute_local() 2024-01-03 14:08:34 +00:00

Jaro Habiger 3200a3961d build.run: factor out extract method 2024-01-03 14:08:34 +00:00
Catherine 5d9ad62f36 build.plat,vendor: start build.sh with #!/bin/sh. 
The build scripts generated by Amaranth are designed to be invoked by
directly running them with any shell (some of them will re-invoke
themselves with `bash` specifically, when it's a toolchain requirement),
and they're not currently marked executable, so there's no shebang.

Add a shebang line to improve compatibility with cases where they are
treated as executables in their own right.

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.
