7  Synopsis [Implements the partition of a network considering only the
8  functions at the combinational outputs in terms of the combinational
9  inputs.]
10
11  Description [This module creates a partition where each combinational output
12  is defined in terms of the combinational inputs. More specifically, for each
13  combinational output and for some combinational inputs, there is a vertex in
14  the partition (a combinational input doesn't appear if no combinational
15  output depends on it). There is an edge from combinational input x to
16  combinational output y if the multi-valued function (MVF) for y depends on
17  x. Every vertex in the graph has a vertex name and an MVF (for combinational
18  inputs, the MVF is the trivial variable function). In addition, each
19  combinational input has an MDD id; a combinational output may or may not
20  have an MDD id.]

53  Synopsis [Creates the graph representing a set of Mvfs as functions of the
54  variables in the collective support of the specified Mvfs. A copy of the Mvf
55  function is stored in vertex.]
56
57  Description [The input nameToMvf is a table which provides the names and the
58  corresponding Mvfs functions.  The procedure works as follows. For each
59  function, a vertex in the graph is created. For each variable in the support
60  of a given MVF, a vertex is created (if one doesn't already exist), and an
61  edge is added from the that vertex to that MVF. The support of an MVF is
62  taken as the union of the support of its constituent MDDs. The table nameToId
63  is optional and can be NULL. It provides a map from the name of the MVF to
64  its mddId. leafTable provides the pair (mddId, name) for each variable in the
65  support of the MVFs. partName can be NULL in which case the name of the
66  partition would be "dummy".]

525
526  Synopsis [Creates the graph representing the combinational outputs as
527  functions of the combinational inputs.]
528
529  Description [The procedure works as follows. It calls the function
530  Ntm_NetworkBuildMvfs with the combinational outputs as roots and the
531  combinational inputs as leaves to obtain the multi-valued functions for
532  every combinational output.  For each combinational output, a vertex in the
533  graph is created. For each combinational input in the support of a given
534  combinational output MVF, a vertex is created for the combinational input
535  (if one doesn't already exist), and an edge is added from the combinational
536  input to the combinational output. The support of an MVF is taken as the
537  union of the support of its constituent MDDs.]
