The distutils module from the standard library is deprecated and will
be removed in Python 3.12, and PEP 632 recommends using
distutils.ccompiler from setuptools, instead.
This code should eventually be rewritten to use zig-pypi, but for now
this suffices.
Avoid calling `__getattr__("_ValueCastable__lowered_to")` when
a ValueCastable has custom `__getattr__` implementation; this avoids
the need for downstream code to be aware of this implementataion
detail.
Using `sum(lst, [])` to flatten a list of lists has quadratic time
complexity. Use `chain.from_iterable()` instead. While not strictly
necessary to improve performance, convert to `map()`.
A test case writing out verilog for a 512k entry FIFO is 120x faster
with this applied.
This merges existing code, and also adds support for:
- Virtex, Virtex E (also known as Spartan 2, Spartan 2E)
- Virtex 2, Virtex 2 Pro
- Spartan 3, Spartan 3E (in addition to existing Spartan 3A, Spartan 3A
DSP support)
- Virtex 4
- Virtex 5
- Virtex 6
- ISE synthesis for Series 7
Fixes#552.
The `test_toolchain_cxx.py` tests on Gentoo definitely use compiler and
linker set with `_so_cxx`-suffixed executables. Tests use a proper
executable instead of `c++` after this change.

Prefix "tools" with symbiflow_ as is done for the QuickLogic Symbiflow
toolchain. Installing symbiflow gives me the tools with the preifx, so I
guess this is the correct way to move forward.
This was an especially insidious bug because the minus character is
valid in case values but has a completely different meaning (wildcard
rather than sign).
Fixes#559.
The OpenOCD scripts for EOS-S3 are roughly equivalent to SVF files
for a more traditional FPGA, which we also produce, for some common
"default" configuration, as a part of the build process.
Commit abbebf8e used __getattr__ to proxy Value methods called on
Record. However, that did not proxy operators like __add__ because
Python looks up the special operator methods directly on the class
and does not run __getattr__ if they are missing.
Instead of using __getattr__, explicitly enumerate and wrap every
Value method that should be proxied. This also ensures backwards
compatibility if more methods are added to Value later.
Fixes#533.
These only matter in simulation and after conversion to Verilog.
During synthesis they cause Yosys to produce warnings:
Warning: Wire $verilog_initial_trigger has an unprocessed 'init' attribute.
