Merge pull request #30 from povik/&mfs-fixes 
Address some `&mfs` crashes

Martin Povišer 1107634fa6 &mfs: Make it no biggie when a network is all blackboxes, no whiteboxes 2024-03-22 22:47:40 +01:00
Martin Povišer d7fc8fe98f &mfs: Handle blackboxes robustly 
When the network is being handed over to the "sfm" core, all blackboxes
are modeled by inserting new PIs, POs, and those being connected by
buffers to the nodes representing the CIs, COs. Make two changes:

 * Robustly deny the fake PIs from being considered when shopping for
   LUT fanin substitutions. Such reconnection occurring would trip up
   the code reintegrating the result.

 * Make sure the buffer connecting the fake-PO to the CO doesn't get
   rewritten as part of the `mfs` transformation, and extend this
   protection to any whitebox models.

Martin Povišer fda490235e &mfs: Fix issues with traversal when re-importing network 
The former implementation of `Sfm_NtkDfs` was trying to serialize the
network while ordering all box inputs ahead of the box outputs. This is
sometimes impossible, leaving the result unordered, which led to crashes
in the `&mfs` code when it was reintegrating the result into the GIA
structure:

  ABC: Assertion failed: iLitNew >= 0 (src/aig/gia/giaMfs.c: Gia_ManInsertMfs: 388)

With a small change to `Gia_ManInsertMfs` which does the reintegration
we don't really need the ordering to see through boxes, ordering on the
paths between boxes is sufficient. Relaxing the ordering requirement, we
make `Sfm_NtkDfs` robust.
