- Status database only gets called from summary events instead of from engines.
- More trace witnesses (.aiw and .yw) are tracked as events.
- Multiple tracefiles can be included in the same trace summary, varying only by
extension. These are ordered by priority so that in the logfile only a single
tracefile is listed.
- For engines where multiple properties can be collected for a single trace,
these properties are now available for all traces until the next step. If any
properties are collected but never recorded with a trace, an error is raised.
- Fix formatting for events without steps (e.g. running abc with `vcd off`).
- Drop task_property_data table entirely, since it is now redundant and unused.
- Fix properties being skipped in all status dump if they don't have a trace.
Setting task property status accepts an optional trace id for associating a prop status with a trace.
Where relevant, delays adding prop status(es) to the database until the corresponding tracefile is known, similar to how tracefiles and prop statuses are linked during the summary.
`SbyTask::update_status()` optionally takes the current step/depth, which gets used for some solvers/engines when exiting to pass unknown properties.
btor engine tracks the current step, but it doesn't track/report which property triggered a CEX so it's only useful on exit.
Use data source as a fallback if engine isn't provided (such as when coming from the `task_status` instead of an engine update).
Currently unconditional, and only for aiger and smtbmc.
Uses task.name from intertask cancellation.
Stores `time.time()` when calling `SbyStatusDb::create_task()` in order to calculate time since start of task (consider reducing to integer seconds).
* to address #296
* this also required some changes to the formatting of the output from
smtbmc to allow more unambiguous parsing, so corresponds to a matching
change in yosys
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.
So far this only passes on the option and adjusts the trace_prefix to
support multiple numbered traces. Further changes are needed to
correctly associate individual traces with the assertions failing in
that trace.
