[MAXVIASTACK value [RANGE bottomLayer topLayer] ;]
The MAXVIASTACK construct is stored in OpenAccess using an oaIntValue for the oacViaStackLimit constraint in the FoundryRules constraint group.
The optional RANGE is stored using oaLayerValues for the oacLowerLayerConstraintParamType and oacUpperLayerConstraintParamType constraint parameters that are applied to the oacViaStackLimit constraint.
The values are stored in an oaViaStackLimits object using the attributes shown in the following table.
| value |

| maxStack |
oaViaStackLimits::MaxStack |
| bottomLayer |
oaViaStackLimits::BottomLayer |
| topLayer |
