Description

Bindings to aig/gia/gia.h for manipulating and running algorithms on scalable and-inverter graphs (GIA), a representation that is optimized for memory-efficiency. These functions power the next-generation of ABC algorithms that have not been officially released yet, and can be identified by the prefix of an ampersand, as in &cec, in the interactive ABC interface.

Synopsis

Documentation

type Gia_Man_t = Ptr Gia_Man_t_ Source

data Gia_Man_t_ Source

giaManNObjs :: Field Gia_Man_t CInt Source

giaManFanData :: Gia_Man_t -> IO (Ptr CInt) Source

type Gia_Obj_t = Ptr Gia_Obj_t_ Source

A pointer to a GIA object. GIA objects are pointers to structs in ABC, and represent literals in the AIG. The low-order bit of the pointer is set to 1 if the literal has been complemented, and so care must be taken to only dereference positive pointers. The object is also a bitfield, so care must be taken when accessing fields.

Pointers to GIA objects may be invalidated when adding a new object.

Also known as the node's id. No complement info.
