---|
| 10 | Performs invairant checking on a flattened network with the GRAB abstraction |
---|
| 11 | refinement algorithm. Before calling this command, the user should have |
---|
| 12 | created the flattened netowrk by calling the commands [1]flatten_hierarchy |
---|
| 13 | and [2]build_partition_maigs. The default BDD manager and network partition |
---|
| 14 | are not mandatory for calling this command, though they will be used if |
---|
| 15 | available. (In other words, the user doesn't have to run the commands |
---|
| 16 | [3]static_order and [4]build_partition_mdds before calling this command.) |
---|
| 17 | Regardless of the options, no 'false positive' or 'false negatives' will |
---|
| 18 | occurs: the result is correct for the given model. Properties to be verified |
---|
| 19 | should be provided as invariant formulae in the file inv_file. Node that the |
---|
| 20 | support of any wire referred to in a formula should consist only of latches. |
---|
| 21 | For the precise syntax of CTL and LTL formulas, see the [5]VIS CTL and LTL |
---|
| 22 | syntax manual. |
---|
| 23 | |
---|
| 24 | If a formula does not pass, a proof of failure (referred to as a |
---|
| 25 | counter-example) is demonstrated. Whether demostrate the proof or not can be |
---|
| 26 | specified (see option -d). |
---|
| 27 | |
---|

---|
| 29 | |

---|
| 59 | Enable or disable the use of fine-grain abstraction. |
---|
| 60 | |
---|
| 61 | finegrain_flag must be one of the following: |
---|
| 62 | |
---|
| 63 | 0: disable fine-grain abstraction. |
---|
| 64 | |
---|
| 65 | 1: enable fine-grain abstraction (Default). |
---|
| 66 | |
---|

---|
| 74 | 1: enable greedy refinement minimization (Default). |
---|
| 75 | |
---|
| 76 | -i |
---|
| 77 | Print input values causing transitions between states during |
---|

---|
| 82 | |
---|
| 83 | -t <timeOutPeriod> |
---|
| 84 | Specify the time out period (in seconds) after which the command |
---|
| 85 | aborts. By default this option is set to infinity. |
---|
| 86 | |
---|
| 87 | -v <verbosity_level> |
---|
| 88 | Specify verbosity level. This sets the amount of feedback on CPU |
---|
| 89 | usage and code status. |
---|
| 90 | verbosity_level must be one of the following: |
---|
| 91 | |
---|
| 92 | 0: No feedback provided. This is the default. |
---|
| 93 | |
---|
| 94 | 1: Feedback on code location. |
---|
| 95 | |
