Minimizing Parallelism Effects
Long, parallel wires can affect signal integrity by introducing crosstalk. To minimize the effects of parallelism, you can specify minimum spacing requirements for different lengths of wire using set_layer_constraint -constraint minSpacing. For example:
set_layer_constraint -constraint minSpacing -layer M2 -row_name length -OneDTblValue { 0 0.1 50 0.2 100 0.3 150 0.4 }
This command results in the following minimum spacing requirements for M2.
| Length | Minimum Spacing |
