This module contains the implementation of a bitblaster for BitVec expressions (BVExpr). That is, expressions that evaluate to BitVec again. Its used as a building block in bitblasting general BitVec problems with boolean substructure.

def Std.Tactic.BVDecide.BVExpr.bitblast {w : Nat} (aig : Std.Sat.AIG Std.Tactic.BVDecide.BVBit) (expr : Std.Tactic.BVDecide.BVExpr w) : Std.Sat.AIG.RefVecEntry Std.Tactic.BVDecide.BVBit w

Equations

• Std.Tactic.BVDecide.BVExpr.bitblast aig expr = (Std.Tactic.BVDecide.BVExpr.bitblast.go aig expr).val
