ABC: System for Sequential Logic Synthesis and Formal Verification
ABC: System for Sequential Logic Synthesis and Formal Verification
ABC is always changing but the current snapshot is believed to be stable.
Compiling:
To compile ABC as a binary, download and unzip the code, then type "make".
@ -13,14 +11,23 @@ To compile ABC as a static library, comment out #define _LIB in file
When ABC is used as a static library, two additional procedures, Abc_Start()
and Abc_Stop(), are provided for starting and quitting the ABC framework in
the calling application. A simple demo program (file demo.c) shows how to
the calling application. A simple demo program (file src/demo.c) shows how to
create a stand-alone program performing DAG-aware AIG rewriting, by calling
APIs of ABC compiled as a static library.
To build the demo program
- Copy libabc.a to the working directory
To build demo program
- Copy demo.cc and libabc.a to the working directory
- Run "gcc -Wall -g -c demo.c -o demo.o"
- Run "gcc -g -o demo demo.o -lm -ldl -rdynamic -lreadline -ltermcap -lpthread libabc.a"
- Run "gcc -g -o demo demo.o libabc.a -lm -ldl -rdynamic -lreadline -ltermcap -lpthread"
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.
