whitequark 23da2fdda6 vendor.xilinx_{7series,ultrascale}: remove grade property. 
This was added in commit bfd4538d based on a misunderstanding of how
Xilinx part numbers work.
 * non-ultrascale 7-series parts don't have temperature grades;
 * ultrascale parts have temperature grade as a part of speed grade.

whitequark 6d417568ad back.pysim: only extract signal names if VCD is requested. 
This commit also fixes an issue introduced in 2606ee33 that regressed
simulator startup time and bloated VCD files. (It's actually about
10% faster now than *before* the regression was introduced.)

whitequark cee43f0de1 back.pysim: simplify. 
Compiled process names were never particularly useful (comments in
the source would make more sense for debugging), and coroutine
process names were actually source locations.

whitequark 369bc3e307 _yosys→_toolchain.yosys 2020-07-02 18:26:08 +00:00
whitequark 6bfff25e76 vendor: yosys is not a required tool for proprietary toolchains. 
Since commit b9799b4c, the discovery mechanism for the Yosys required
to produce Verilog is different from the usual require_tool(); namely
it is possible to produce Verilog without a `yosys` binary on PATH.

Fixes #419.

whitequark 416b2531ae Revert "Add PEP 518 pyproject.toml." 
This reverts commit 7fca037f9c.

This broke editable installs and has to be reverted due to a number
of pip issues:
  * pypa/pip#6375
  * pypa/pip#6434
  * pypa/pip#6438

We can put this back once PEP 517/518 support editable installs.
Until then the legacy behavior will suffice, and we should just teach
people to install the dependencies in virtualenvs or something...

whitequark 76c7e70582 docs: add a crude approximation of intersphinx toctrees. 
This is a pretty awful hack. We could do this properly after one of
the following issues is fixed:
  * sphinx-doc/sphinx#701
  * sphinx-doc/sphinx#1836

whitequark 126f0be731 Gracefully handle missing dependencies. 
Some people's workflows involve not using `pip`. This is not
a recommended way to use nMigen, but is prevalent enough for good
enough reason that we try to keep them working anyway.

whitequark 7fca037f9c Add PEP 518 pyproject.toml. 
This is necessary to be able to install nMigen into a virtualenv that
does not have `wheel` installed in certain cases.
