---|
| 9 | Description [The first method groups vertices based on the hierachy of the |
---|
| 10 | system. Normally, the hierachy is formed in the early phase of the |
---|
| 11 | design. We use this information to group latches. The method expects the |
---|
| 12 | high level description languages to BLIF conversion utilities such as vl2mv |
---|
| 13 | to preserve the original hierachy. The second method is explained in the |
---|
| 14 | following paper. |

---|
| 16 | Structural Approach to State Space Decomposition for Approximate |
---|
| 17 | Reachability Analysis," ICCD, pp.236-239, 1994. Traversal," EDAC. |
---|
| 18 | This method groups vertices based on the latch dependency(relation between |
---|
| 19 | latches) and the latch correlation(resemblance of latches in terms of the |
---|
| 20 | support variables.] |

---|
| 124 | Description [From the given latch data inputs, create array of sub-partitions |
---|
| 125 | of vertices. Latch data inputs are given as "latchDataInputNames" and |
---|
| 126 | includes subset of all latches in a system. Since the vertices are defined |
---|
| 127 | as the latch-input nodes, one may think of the process as grouping of |
---|
| 128 | latches in the network. "amc_sizeof_group" value may be set by the user by |
---|
| 129 | using the set command from the vis shell. The function uses this value to |
---|
| 130 | limit the number of vertices(latches) in a single group(subsystem). More |
---|
| 131 | vertices in a subsystem implies its representation is closer to the exact |
---|
| 132 | system. When the value is not given by the user, the default value of 8 |
---|
| 133 | vertices(latches) is used. The routine uses hierachical grouping method. |
---|
| 134 | That is, the latches in the same sub-processes(i.e. same .subckt in BLIF |
---|
| 135 | format), are grouped together whenever possible. |
---|
| 136 | |
---|
| 137 | Initial partition must be performed before executing this routine.] |

| 800 | Synopsis [Create an array of partitioned subsystems from array of latches] |
---|
| 801 | |
---|
| 802 | Description [This is a main function to get subsystems. At first, look at |
---|
| 803 | the circuit topology and next state functions, get the latch affinity. |
---|
| 804 | Find the connected components to cluster latches which are stronly dependent |
---|
| 805 | or correlated on each other. |
---|
| 806 | After that, divide clusters bigger than the given bound and aggregate |
---|
| 807 | smaller clusters. This function is called with network and partition graph. |
---|
| 808 | If arrayOfFunctionNames are not NULL, this function generates sub-system with |
---|
| 809 | those latch-data-inputs in that array. If arrayOfGroupIndex is not NILL and |
---|
| 810 | size of this array is same as the size of arrayOfFunctionNames, this function |
---|
| 811 | uses these two arrays as predefined grouping information and creates |
---|
| 812 | sub-systems.] |

| 1161 | Synopsis [Create an array of subsystems from properties] |
---|
| 1162 | |
---|
| 1163 | Description [The first couple of sub-systems include nodes which are |
---|
| 1164 | in CTL/LTL/fairness formulae. A node with biggest affinity is |
---|
| 1165 | included in the next sub-system until the number of nodes is less |
---|
| 1166 | than bound. If dynamicIncrease is FALSE, get all sub-systems with |
---|
| 1167 | all support variables of CTL formula. If TRUE, the first sub-system |
---|
| 1168 | includes variables in CTL and the second sub-system includes others. |
---|
| 1169 | |
---|
| 1170 | When strictBound is FALSE, all the latches appearing in the formulae |
---|
| 1171 | are put into the first subsystem -- making it possibly larger than |
---|
| 1172 | the bound. Otherwise, no subsystem will have more than 'bound' |
---|
| 1173 | latches.] |
