This commit removes an erroneous "if sbyfile" that would turn '-f' into a no-op
for stdin input files. Presumably this check was originally intended to handle
the case of stdin input file and no specified workdir (which uses a temporary
workdir). In the current version the check is redundant for this particular
case. The check is erroneous in the case of stdin input file and a specified
workdir, so we simply remove the check.
This adds initial support for an sqlite database that is shared across
multiple tasks of a single SBY file and that can track the status of
individual properties.
The amount of information tracked in the database is currently quite
minimal and depends on the engine and options used. This can be
incrementally extended in the future.
The ways in which the information in the database can be queries is even
more limited for this initial version, consisting of a single '--status'
option which lists all properties and their status.
Move parser generation into a seperate file to avoid import issues with bad python modules during docs gen.
With the requirements.txt provided to readthedocs, there shouldn't need to be any other changes?
Also I've never been able to run `make test` so I'm not actually sure if the changes break sby, but they shouldn't.
When using the -f argument be more forgiving with the expectation of a clean
workspace and the expectation of the new sby run being responsible for
directory creation.
This is a usability and quality of life improvement for Windows users where
the OS can implement file and directory locking implicitly. In the EDA world
it is common to have multiple tools in use at any one time and it can become
tortious to have to close files / exit 3rd party applications to release
locking so sby is happy to rerun.
This change will prevent sby claiming a terminal error has occurred when it
fails to create a directory that already exists. It also now considers the
environment to be 'clean' (as per -f) if all the non-directory elements of
the file tree have been deleted, leaving potentially an empty a skeleton of
directories.
Only implements the POSIX jobserver and will break on windows.
Unbreaking it on windows will be done as a follow up.
Not used for autotune, that needs some more changes.
* Rename and move sbysrc/demo[123].sby to docs/examples/demos
* Make them use multiple tasks for multiple engines
* Scan docs/examples for sby files for make test
* `make ci` is now `NOSKIP` by default
* Skip scripts using `verific` w/o yosys verific support
* This does not fail even with NOSKIP set
