Topology Pattern Database Access Functions
This topic describes the functions that support channel-based routing. These functions can be classified into different topology patterns and are defined to create, process, or return an object specified by a topology pattern ID.
The definitions of the common topology patterns are as given below.
|
Topology Pattern
|
The set of rules for a channel-based router so that it automatically performs trunk-based routing. The different topology patterns are specified as follows:
-
Twig
-
Trunk
-
Trunk Connection
-
Strap
|
|
Trunk
|
An interconnect connection between instTerms that runs parallel to a channel.
|
|
Twig
|
An interconnect connection between instTerms that runs perpendicular to a channel and connects trunks to a different instTerm.
|
|
Trunk Connection
|
The connection between more than one trunks, also called a dogleg.
A vertical and a horizontal trunk are connected together using a trunk connection.
|
|
Strap
|
The connection between a number of instTerms. A strap is connected to a trunk using a twig.
A strap can have multiple geometric segments.
