/*
In the netlist, the PI/PO arrays store PI/PO nets.
The names belongs to the nets and are stored in pNet->pData.
When a netlist is made combinational:
- LO/LI nets are added to PI/PO arrays,
- the array of latches is temporarily stored in vLatch2,
- the original number of PIs/POs is remembered in nPisOld/nPosOld.
In a logic network, the PI/PO arrays store PI/PO nodes.
The PO nodes have only one fanin edge, which can be complemented.
The arrays vNamesPi/vNamesPo/vNamesLatch store PI/PO/latch names.
The internal nodes are nameless.
When a logic network is made combinational:
- laches are added to the PI/PO arrays,
- the arrays of names are not changed,
- the array of latches is temporarily stored in vLatch2,
- the original number of PIs/POs is remembered in nPisOld/nPosOld.

Synopsis [Performs fast_extract on a set of covers.]
Description [All the covers are given in the array p->ppCovers.
The resulting covers are returned in the array p->ppCoversNew.
The number of entries in both cover arrays is equal to the number
of all values in the current nodes plus the max expected number
of extracted nodes (p->nValuesCi + p->nValuesInt + p->nValuesExtMax).
The first p->nValuesCi entries, corresponding to the CI nodes, are NULL.
The next p->nValuesInt entries, corresponding to the int nodes, are covers
from which the divisors are extracted. The last p->nValuesExtMax entries
are reserved for the new covers to be extracted. The number of extracted
covers is returned. This number does not exceed the given number (p->nNodesExt).
Description [All the covers are given in the array p->vSops.
The resulting covers are returned in the array p->vSopsNew.
The entries in these arrays correspond to objects in the network.
The entries corresponding to the PI and objects with trivial covers are NULL.
The number of extracted covers (not exceeding p->nNodesExt) is returned.
Two other things are important for the correct operation of this procedure:
(1) The input covers should be SCC-free. (2) The literal array (pCover->pLits)
is allocated in each cover. The i-th entry in the literal array of a cover
is the number of the cover in the array p->ppCovers, which represents this
literal (variable value) in the given cover.]
(1) The input covers do not have duplicated fanins and are SCC-free.
(2) The fanins array contains the numbers of the fanin objects.]
