Abstract
Loop abstraction includes determining an original loop within the source code. The original loop includes a control statement and a loop body such that the original loop causes the loop body to be repeatedly executed based on the control statement. Further, output variables in the original loop and a number of blocks associated with the original loop are identified. The number of blocks is indicative of a count of unconditionally executed statement sets in which at least one output variable is computed. An abstract loop corresponding to the original loop is generated by adding a modified expression for accelerated assignment for each output variable in a subset of the output variables, and replacing the control statement with a bounded control statement. The original loop is replaced with the abstract loop for generating an abstract source code for the model checking.
