Catherine fc7c86bbe6 docs/changes: link to docs for past releases. 2024-01-29 19:33:39 +00:00
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 b823a8ee9d build.run: add BuildPlan.execute_docker() 
One usecase for this is using amaranth with vivado on macOs.

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.

Catherine 1d3a62093b docs/changes: call out backwards incompatibility with Pin. 2023-09-05 14:07:33 +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.

Bastian Löher 93e89f5632 vendor.gowin: new platform. 
Co-authored-by: Catherine <whitequark@whitequark.org>
 2023-08-08 12:38:36 +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.
