# dddmpBinary.c

Input and output BDD codes and integers from/to file

By: Gianpiero Cabodi and Stefano Quer

Input and output BDD codes and integers from/to file in binary mode. DD node codes are written as one byte. Integers of any length are written as sequences of "linked" bytes. For each byte 7 bits are used for data and one (MSBit) as link with a further byte (MSB = 1 means one more byte). Low level read/write of bytes filter , and with escape sequences.

# dddmpLoad.c

Functions to read in bdds to file

By: Gianpiero Cabodi and Stefano Quer

Functions to read in bdds to file. BDDs are represended on file either in text or binary format under the following rules. A file contains a forest of BDDs (a vector of Boolean functions). BDD nodes are numbered with contiguous numbers, from 1 to NNodes (total number of nodes on a file). 0 is not used to allow negative node indexes for complemented edges. A file contains a header, including information about variables and roots to BDD functions, followed by the list of nodes. BDD nodes are listed according to their numbering, and in the present implementation numbering follows a post-order strategy, in such a way that a node is never listed before its Then/Else children.
