Catherine 47851c2328 vendor.GowinPlatform: fix fencepost error in oscillator range.

Catherine bfd62569c8 vendor.GowinPlatform: improve oscillator frequency diagnostic. 2023-09-25 08:41:49 +00:00
Wanda 05cb82b8fc ast: fix const-castable expression handling in Signal(reset=). 
The code to accept const-castable expressions was previously added in
0c4fda92fe, but it was untested and had
a few bugs.

Fixes #911.

crzwdjk 11d5bb19eb vendor._lattice_ice40: add an icepack_opts override 
Add an icepack_opts override in case the user wants to pass
extra options to icepack as part of the build process.

Catherine ecba1a1863 back.rtlil: put hierarchy in module name instead of an attribute. 
The attribute sees essentially no use and the information is much
better served by putting it in the module name. In addition this
means that the entire tree can be renamed simply by renaming the top
module.

Tools like GTKWave show the names of the instances, not the modules,
so they are not affected by the longer names.

Catherine d32ca04326 pyproject: migrate to PDM build backend. 
`.git_archival.txt` and the functionality of deriving SCM version
from a GitHub generated archive is removed pending implementation of
pdm-project/pdm-backend#194.
 2023-09-12 01:40:48 +00:00
Catherine a9d03805ff lib.io: add a deprecation warning on Pin.eq. 
This will stop working once `Pin` is no longer inheriting from
`Record`.
 2023-09-05 14:07:33 +00:00
Catherine 1d3a62093b docs/changes: call out backwards incompatibility with Pin. 2023-09-05 14:07:33 +00:00
Catherine 6683c3a916 hdl.mem: fix INIT parameter of emitted $mem_v2 cell. 
Unspecified memory slots are initialized to zero, not uninitialized.
 2023-09-05 13:25:55 +00:00
Catherine c53eee961c back.rtlil: fix MEMID parameter to match $mem_v2 cell name. 2023-09-05 13:25:55 +00:00
Catherine 525c7e2be0 back.rtlil: do not translate empty subfragments at all. 
It was thought previously (by me) that adding a wire that does
nothing to an empty subfragment is enough to prevent it from being
treated as a blackbox. This is enough for Yosys but not Vivado.
Another workaround could probably be used that satisfies both, but
instead let's just not translate any empty subfragments.

This doesn't account for the case of the empty toplevel, but that
does not seem worth addressing.

Fixes #899.

Catherine 4e078322a0 lib.io: make Pin an interface object. 
Tracking #879.

The directions of signals in `Pin` make it convenient to use a pin
signature in a component, such as in:

    class LEDDriver(Component):
        pins: Out(Signature({"o": Out(1)}))

    led_driver = LEDDriver()
    connect(led_driver.pins, platform.request("led"))

The `platform.request` call, correspondingly, returns a flipped `Pin`
object.

Catherine 33c2246311 back.{verilog,rtlil}: in convert(), accept a Component without ports. 
Closes #883.

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.

Tracking #879.

Catherine 7f1397b281 vendor/*: add missing __all__. 
This broke code that did e.g.

    from amaranth.vendor.xilinx import *

which is common in amaranth-boards.

Catherine 88cbf30128 lib.wiring: use is for type comparison in Component. 
This avoids running custom `__eq__` implementations, which could
cause issues such as #882.

Catherine 7714ce329a Fix broken commit c9fd0d83. 2023-08-22 17:15:15 +00:00
Catherine c9fd0d8391 build.run: prohibit absolute paths in BuildPlan.add_file. 
This makes the build impure and also causes the contents of a file
outside of the build directory to be overwritten.

The check in `BuildPlan.execute_local` is also expanded to cover
the possibility of an absolute path sneaking through.

Catherine 20e8bbdfbd Bring __version__ retrieval up to date. NFCI 
Because `importlib.metadata.PackageNotFoundError` inherits from
`ImportError`, the code did not previously work in the way that was
stated in the comment. We should probably deprecate `__version__`
entirely at some point.
