Component Library

This selection contains a list of the components extracted from the ODB++ file. For each component it should include:

Component Name and Part Number

Component Outline

Component Outline Extents

List of Pins

Component Attributes

This is not a "true" library in the sense that for each instance of a component found in the ODB++ file a new entry is created. A true library would only have a single component definition no matter how many times the component was placed.

Annotated Sample

The sample below was extracted from an NJB file produced by NETEX-G.

B_COMP_DEF                                 starts the component definition
1 "220-01720-05a_PKG0" "DO214AA_POKA"      the component's name & symbols name
                                           note that we append a PKG0 to this
                                           to make it unique. If the same comp
                                           is used again, it will have a different
                                           PKG value.
