Module topo_xbar
Sparse Crossbar topology.
Attaches a Split node to every output that has more than one physical fanout. Attaches a Merge node to every input that has more than one physical fanin. Connects the Splits to the Merges, with optional Buffer Nodes after each Split or Merge.
Usage:
b:system('mysys', topo_xbar)b:system('mysys', make_topo_xbar(true, false, true))
Functions
| topo_xbar (sys) | Default version that adds buffers after merge nodes only. |
| make_topo_xbar (reg_split, reg_merge, reg_internal) | Returns a customized topo_xbar topology function. |
