Cadence Allegro 17.4 主要LIB库文件介绍

The share folder contains the footprint models (called symbols), which are files with the .dra extension.
Most parts in Capture are capable of having a PSpice template or a footprint assigned to them, but only some parts have them preassigned.

Only parts from the PSpice part library (located in the capture/library/PSpice folder) have preassigned templates and footprints.

SPB_17.4\share\pcb\pcb_lib\symbols

The OLB files located directly in the Capture library folder contain simple schematic part symbols ：

SPB_17.4\tools\capture\library

The libraries located in the PSpice folder contain parts with schematic symbols, too, but the parts also contain PSpice templates, which are links to specific PSpice models.

SPB_17.4\tools\capture\library\pspice

Parts from the PSpice part library (located in the capture/library/PSpice folder) have preassigned templates and footprints.

The PSpice models to which templates point are located in the main OrCAD PSpice folder：

SPB_17.4\tools\pspice\library

Individual models are grouped into various PSpice library files, which contain the .LIB extension.
