System on Chip toolkit for Amaranth HDL
In multiple places I end up needing an enable signal that generates ones at a given frequency in relation to the domain clock. This is a proposal for a generic...
This PR migrates existing docstrings to numpydoc and renders them with `pdm run document` alongside upstream documentation. Docstring content is (mostly) left untouched and will be the focus of the...

Currently, `csr.Builder` works around this by casting array indices to strings calling `MemoryMap.add_resource()`. Repro: ```python3 from amaranth import * from amaranth_soc import csr class FooRegister(csr.Register, access="r"): a: csr.Field(csr.action.R, unsigned(8)) regs...
Depends on PR amaranth-lang/amaranth#978. `MemoryMap` resources (e.g. `csr.Element`s) are now assumed to have a `.signature` property, which lets them hold annotations. I am not sure whether we should enforce this...
Peripherals are a currently missing building block from nmigen-soc. They would provide wrappers to cores by means of a CSR interface (also interrupts, but handling these could be the subject...
Apparently, resources in a dense memory window cannot be smaller than the data width of the parent memory map. This can be demonstrated in `test_memory.py` by making the resource in...
