Using AIG Package in ABC
|
||
|
|
|
||
|
|
- Download the latest snapshot of ABC
|
||
|
|
- Compile the code found in "abc\src\aig\aig", "abc\src\aig\saig", and "abc\src\misc\vec" as a static library.
|
||
|
|
- Link the library to the project.
|
||
|
|
- Add #include "saig.h".
|
||
|
|
- Start the AIG package using Aig_ManStart().
|
||
|
|
- Assign primary inputs using Aig_ObjCreatePi().
|
||
|
|
- Assign register outputs using Aig_ObjCreatePi().
|
||
|
|
(it is important to create all PIs first, before creating register outputs).
|
||
|
|
- Construct AIG in the topological order using Aig_And(), Aig_Or(), Aig_Not(), etc.
|
||
|
|
- If constant-0/1 AIG nodes are needed, use Aig_ManConst0() or Aig_ManConst1()
|
||
|
|
- Create primary outputs using Aig_ObjCreatePo().
|
||
|
|
- Create register inputs using Aig_ObjCreatePo().
|
||
|
|
(it is important to create all POs first, before creating register inputs).
|
||
|
|
- Set the number of registers by calling Aig_ManSetRegNum().
|
||
|
|
- Remove dangling AIG nodes (produced by structural hashing) using Aig_ManCleanup().
|
||
|
|
- Call the consistency checking procedure Aig_ManCheck().
|
||
|
|
- Dump AIG into a file using the new BLIF dumper Saig_ManDumpBlif().
|
||
|
|
- For each object in the design annotated with the constructed AIG node (pNode), remember its AIG node ID by calling Aig_ObjId( Aig_Regular(pNode) ). To check whether the corresponding AIG node is complemented use Aig_IsComplement(pNode).
|
||
|
|
- Quit the AIG package using Aig_ManStop().
|
||
|
|
The above process should not produce memory leaks.
