CPAchecker Analysis Report

Quick Reference to use the report

  • Left Panel: Error Path (if a bug is found)

    • Indentation reflects height of call stack.
    • Function Start, Function Return, and unlabeled edges are not displayed.
    • Click table element to jump to its location in the CFA/ARG/Source (depending on the active tab). If none of the mentioned tabs is selected, ARG will become active.
    • Use Start (or click table element) and Prev/Next to walk along the error path.

  • Right Panel:

    • CFA Tab

      • The CFA is divided into multiple graphs (one graph per function). Initially all graphs are displayed below one another beginning with the program entry function, i.e. main(). Change the displayed function by using the Displayed CFA select box or by double clicking on a function call node (square element in graph).
      • Linear sequences of "normal" edges (StatementEdges, DeclarationEdges, and BlankEdges) are displayed as a multi-label node. Each line contains the predecessor node and the edge label. The successor can be found in the left of the next line.
      • The error path is highlighted in red.
      • Hover over a graph element to display additional information.
      • Double-click an edge to jump to the location in the source code.

    • ARG Tab

      • The error path is highlighted in red.
      • Use the Displayed ARG select box to alter between the complete ARG and an ARG graph containing only the error path.
      • Hover over a graph element to display additional information.
      • Double-click a node to jump to the location in the CFA.

    • Source Tab

      • Displays source code.

    • Log Tab

      • Displays the Log output of CPAchecker.

    • Statistics Tab

      • Displays the Statistics output of CPAchecker.

    • Configurations Tab

      • Displays the Configurations used by CPAchecker.

    • Help button

      • Click to display additional information for the right panel.

Known Problems

  • When a specific CFA function is displayed and an error path element, that is not contained in said function, is selected, the displayed function does not change. Workaround: Select all in the Displayed CFA select box and click the error path element again.

  • When an item is selected in the error path window on the left, only the active tab on the right is updated. Workaround: After changing the tab on the right, click the selected item in the error path window again.
