|---|
|  | 121 |  | 
|---|
|  | 122 | CommandDescription [This command verifies the combinational equivalence of | 
|---|
|  | 123 | two flattened networks.  In particular, any set of functions (the roots), | 
|---|
|  | 124 | defined over any set of intermediate variables (the leaves), can be checked | 
|---|
|  | 125 | for equivalence between the two networks.  Roots and leaves are subsets of | 
|---|
|  | 126 | the nodes of a network, with the restriction that the leaves should form a | 
|---|
|  | 127 | complete support for the roots. The correspondence between the roots and the | 
|---|
|  | 128 | leaves in the two networks is specified in a file given by the option -f | 
|---|
|  | 129 | <filename>. The default option | 
|---|
|  | 130 | assumes that the roots are the combinational outputs and the leaves are the | 
|---|
|  | 131 | combinational inputs.<p> | 
|---|
|  | 132 |  | 
|---|
|  | 133 | When there is a pseudo input in the set of leaves, the range of values it | 
|---|
|  | 134 | can take should be the same as that of the multi-valued variable | 
|---|
|  | 135 | corresponding to it, for comb_verify to function correctly. | 
|---|
|  | 136 | This restriction will be removed in future.<p> | 
|---|
|  | 137 |  | 
|---|
|  | 138 | There are two ways to do combinational verification.  In the first mode, two | 
|---|
|  | 139 | BLIF-MV files are given as arguments to the command, e.g.<p> | 
|---|
|  | 140 |  | 
|---|
|  | 141 | <pre> | 
|---|
|  | 142 | vis> comb_verify foo.mv bar.mv | 
|---|
|  | 143 | </pre> | 
|---|
|  | 144 |  | 
|---|
|  | 145 | Verification is done for the flattened networks at the root nodes of the two | 
|---|
|  | 146 | BLIF-MV hierarchies.  In any error messages printed, "network1" refers to | 
|---|
|  | 147 | the first file, and "network2" refers to the second. Both of these networks | 
|---|
|  | 148 | are freed at the end of the command. This mode is totally independent from | 
|---|
|  | 149 | any existing hierarchy previously read in. | 
|---|
|  | 150 |  | 
|---|
|  | 151 | In the second mode, it is assumed that a hierarchy has already been read | 
|---|
|  | 152 | in. Then, comb_verify can be called with a single BLIF-MV file, and this | 
|---|
|  | 153 | will do the comparison between the network present at the current node | 
|---|
|  | 154 | ("network1") and the network corresponding to the root node of the hierarchy | 
|---|
|  | 155 | in the BLIF-MV file("network2"). A typical sequence of commands is:<p> | 
|---|
|  | 156 |  | 
|---|
|  | 157 | <pre> | 
|---|
|  | 158 | vis> read_blifmv foo.mv | 
|---|
|  | 159 | vis> init_verify | 
|---|
|  | 160 | vis> comb_verify bar.mv | 
|---|
|  | 161 | </pre> | 
|---|
|  | 162 |  | 
|---|
|  | 163 | If a hierarchy has been read in but a flattened network does not exist at | 
|---|
|  | 164 | the current node (flatten_hierarchy has not been invoked), the command does | 
|---|
|  | 165 | nothing. If a network exists at the | 
|---|
|  | 166 | current node, but the variables haven't been ordered, then the variables are | 
|---|
|  | 167 | ordered and a partition created. This partition is freed at the end. A | 
|---|
|  | 168 | side-effect is that the variables are ordered. If a partition exists, then | 
|---|
|  | 169 | it is used if the vertices corresponding to the roots specified are present | 
|---|
|  | 170 | in it, otherwise a new partition is created with the current ordering. The | 
|---|
|  | 171 | partition created for the new network read in is always freed at the end.<p> | 
|---|
|  | 172 |  |

|  | 173 | Command options:<p> |

|  | 181 | <dt> -f <filename> | 
|---|
|  | 182 | <dd> Provides the correspondence between the leaves and roots of | 
|---|
|  | 183 | network1 and network2. If this option is not used, it is assumed | 
|---|
|  | 184 | that the correspondence is by name, except that two latch inputs | 
|---|
|  | 185 | match if either they have the same name or the corresponding latch | 
|---|
|  | 186 | outputs have the same name.  Leaves are the combinational inputs, | 
|---|
|  | 187 | and roots are the combinational outputs.  <p> |

|---|
|  | 207 | <code>build_partition_mdds</code> for more information). If this option is | 
|---|
|  | 208 | not specified, then the default method "inout" is used.  <p> | 
|---|
|  | 209 |  | 
|---|
|  | 210 | <dt> -2 <partition method> |

|  | 729 | CommandSynopsis [verify the sequential equivalence of two flattened networks] | 
|---|
|  | 730 |  | 
|---|
|  | 731 | CommandArguments [\[-b\] \[-f <filename>\] \[-h\] \[-p <partition | 
|---|

|---|
|  | 733 |  | 
|---|
|  | 734 | CommandDescription [Please read the documentation for the command | 
|---|
|  | 735 | <code>comb_verify</code> before reading on. The concepts of roots and leaves | 
|---|
|  | 736 | in this command are the same as for <code>comb_verify</code>, except for an | 
|---|
|  | 737 | added constraint: the set of leaves has to be the set of all primary inputs. | 
|---|
|  | 738 | This obviously produces the constraint that both networks have the | 
|---|
|  | 739 | same number of primary inputs. Moreover, no pseudo inputs should be present | 
|---|
|  | 740 | in the two networks being compared. The set of roots can be an arbitrary | 
|---|
|  | 741 | subset of nodes.<p> | 
|---|
|  | 742 |  | 
|---|
|  | 743 | The command verifies whether any state, where the values of two | 
|---|
|  | 744 | corresponding roots differ, can be reached from the set of | 
|---|
|  | 745 | initial states of the product machine. If this happens, a debug trace is | 
|---|
|  | 746 | provided.<p> | 
|---|
|  | 747 |  | 
|---|
|  | 748 | The sequential verification is done by building the product finite state | 
|---|
|  | 749 | machine.<p> | 
|---|
|  | 750 |  | 
|---|
|  | 751 | The command has two execution modes, just as for <code>comb_verify</code>. | 
|---|
|  | 752 | In the first mode, two BLIF-MV files are given as arguments to the | 
|---|
|  | 753 | command:<p> | 
|---|
|  | 754 |  | 
|---|
|  | 755 | <pre> | 
|---|
|  | 756 | vis> seq_verify foo.mv bar.mv | 
|---|
|  | 757 | </pre> | 
|---|
|  | 758 |  | 
|---|
|  | 759 | In the second mode, a single BLIF-MV file is taken. This is network2. It is | 
|---|
|  | 760 | assumed that network1 is from a hierarchy that has already been read in. If | 
|---|
|  | 761 | a network is present at the current node (i.e. flatten_hierarchy has been | 
|---|
|  | 762 | executed), it is used for verification; otherwise the command does | 
|---|
|  | 763 | nothing.<p> | 
|---|
|  | 764 |  | 
|---|
|  | 765 | <pre> | 
|---|
|  | 766 | vis> read_blifmv foo.mv | 
|---|
|  | 767 | vis> flatten_hierarchy | 
|---|
|  | 768 | vis> seq_verify bar.mv | 
|---|
|  | 769 | </pre> |

|---|
|  | 778 |  | 
|---|
|  | 779 | <dt> -f <filename> | 
|---|
|  | 780 | <dd> Provides the correspondence between the leaves and roots of network1 | 
|---|
|  | 781 | and network2. leaves has to be the set of primary inputs of the | 
|---|
|  | 782 | networks. roots can be any subset of nodes. If this option is not used, it | 
|---|
|  | 783 | is assumed that the correspondence is by name, and that the roots are the | 
|---|
|  | 784 | combinational outputs.  <p> | 
|---|
|  | 785 |  | 
|---|
|  | 786 | <dt> -h | 
|---|
|  | 787 | <dd> Print the command usage. |

|  | 788 | <p> | 
|---|
|  | 789 |  | 
|---|
|  | 790 | <dt> -p <partition method> | 
|---|
|  | 791 | <dd> Specifies the partitioning method for the product machine. Supported | 
|---|
|  | 792 | methods are "total", "partial", and "inout" (see the command | 
|---|
|  | 793 | <code>build_partition_mdds</code> for more information). If this option is | 
|---|
|  | 794 | not specified, then the default method "inout" is used. | 
|---|
|  | 795 | <p> | 
|---|
|  | 796 |  | 
|---|
|  | 797 | <dt> -t <timeOut> | 
|---|
|  | 798 | <dd> Time in seconds allowed to perform equivalence checking.  The default |

|  | 799 | is infinity.<p> | 
|---|
|  | 800 |  | 
|---|
|  | 801 | <dt> -B | 
|---|
|  | 802 | <dd> Use backward image computation to traverse the state space of | 
|---|
|  | 803 | the product machine.  By default, forward image computaion is used. | 
|---|
|  | 804 |  | 
|---|
|  | 805 | <dt> -i | 
|---|
|  | 806 | <dd> Print BDD statistics. This is the only way to see BDD stastics during | 
|---|
|  | 807 | this command. print_bdd_stats after this command doesn't show information | 
|---|
|  | 808 | related to this command. | 
|---|
|  | 809 |  | 
|---|
|  | 810 | <dt> -r | 
|---|
|  | 811 | <dd> Enable BDD reordering during the equivalence check.  Note that | 
|---|
|  | 812 | dynamic_var_ordering has no effect on whether reordering is enabled during | 
|---|
|  | 813 | the execution of seq_verify. |
