7 | Synopsis [Routines for grouping vertices.] |
---|
8 | |
---|
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. |
---|
15 | H. Cho, G. D. Hachtel, E. Macii, B. Plessier, F. Somenzi," A |
---|
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.] |

123 | |
---|
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.] |
