- 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.
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
