---|
| 10 | Performs invairant checking on a flattened network with the GRAB |
---|
| 11 | abstraction refinement algorithm. Before calling this command, the |
---|
| 12 | user should have created the flattened netowrk by calling the commands |
---|
| 13 | [1]flatten_hierarchy and [2]build_partition_maigs. The default BDD |
---|
| 14 | manager and network partition are not mandatory for calling this |
---|
| 15 | command, though they will be used if available. (In other words, the |
---|
| 16 | user doesn't have to run the commands [3]static_order and |
---|
| 17 | [4]build_partition_mdds before calling this command.) Regardless of |
---|
| 18 | the options, no 'false positive' or 'false negatives' will occurs: the |
---|
| 19 | result is correct for the given model. Properties to be verified |
---|
| 20 | should be provided as invariant formulae in the file inv_file. Node |
---|
| 21 | that the support of any wire referred to in a formula should consist |
---|
| 22 | only of latches. For the precise syntax of CTL and LTL formulas, see |
---|
| 23 | the [5]VIS CTL and LTL syntax manual. |
---|
| 24 | |
---|
| 25 | If a formula does not pass, a proof of failure (referred to as a |
---|
| 26 | counter-example) is demonstrated. Whether demostrate the proof or not |
---|
| 27 | can be specified (see option -d). |
---|
| 28 | |
---|

---|
| 30 | |

| 60 | -F <finegrain_flag> |
---|
| 61 | Enable or disable the use of fine-grain abstraction. |
---|
| 62 | |
---|
| 63 | finegrain_flag must be one of the following: |
---|
| 64 | |
---|
| 65 | 0: disable fine-grain abstraction. |
---|
| 66 | |
---|
| 67 | 1: enable fine-grain abstraction (Default). |
---|
| 68 | |
---|
| 69 | -M <refinemin_flag> |
---|
| 70 | Enable or disable the use of greedy refinement minimization. |

---|
| 74 | 0: disable greedy refinement minimization. |
---|
| 75 | |
---|
| 76 | 1: enable greedy refinement minimization (Default). |
---|
| 77 | |
---|
| 78 | -i |
---|
| 79 | Print input values causing transitions between states during |
---|
| 80 | debugging. Both primary and pseudo inputs are printed. |

| 83 | Pipe debugger output through the UNIX utility more. |
---|
| 84 | |
---|
| 85 | -t <timeOutPeriod> |
---|
| 86 | Specify the time out period (in seconds) after which the |
---|
| 87 | command aborts. By default this option is set to infinity. |
---|
| 88 | |
---|
| 89 | -v <verbosity_level> |
---|
| 90 | Specify verbosity level. This sets the amount of feedback on |
---|
| 91 | CPU usage and code status. |
---|
| 92 | verbosity_level must be one of the following: |
---|
| 93 | |
---|
| 94 | 0: No feedback provided. This is the default. |
---|
| 95 | |
---|
| 96 | 1: Feedback on code location. |
---|
| 97 | |
