Rout Layer Checks
The Rout
Layer Checks action is a read-only action intended to find potential
manufacturability defects in the Rout Layer. This analysis action is designed
to check chained rout layers, but can also process design data (i.e. raw routing
data as sent from the customer) before any adjustments are made to the data,
such as assign chains, etc.
This action
requires a special license option: routchk.
This action can be
applied to all layer features or to a selected sequence (a selected sequence
contains at least one selected feature). The action gets a rout layer (not
necessary in board context).
It will process Lines
and Arcs features in these layers. If the selected feature has a .comp attribute,
compensation will be taken into
consideration. If the
selected feature does not have this attribute, compensation = none is
assumed.
This action performs
chain checks. Listed below are the current types of chain checks:
1. Find locations that
will create problems for the tool size (defined or default):
• Arcs that are smaller than the tool size (Small Arc)
• Places where two features are closer than the tool size (Too Narrow).
• Lines whose length is less than the tool size (Short Line).
• Arcs whose length is less than the tool size (Short Arc).
2. Report about
features that intersect (go over) each other (Intersection).
Note An unfinished chain is
not processed and is reported in a special category - Unfinished
Chain.
An Unfinished Chain is
a chain where only some of the chain’s features are assigned rout chain attributes.
