To build the demo program To build demo program
- Copy libabc.a to the working directory - Copy demo.cc and libabc.a to the working directory
- Run "gcc -Wall -g -c demo.c -o demo.o" - Run "gcc -Wall -g -c demo.c -o demo.o"

To run demo program, give it a file with the logic network in AIGER or BLIF. For example:
[alanmi@mima] ~/abc> demo i10.aig
i10 : i/o = 257/ 224 lat = 0 and = 2396 lev = 37
i10 : i/o = 257/ 224 lat = 0 and = 1851 lev = 35
Networks are equivalent.
