Allegro/OrCAD FREE Manufacturing Documentation Viewer

The Cadence Allegro/OrCAD FREE Manufacturing Documentation Viewer is a free download that allows you to view documentation generated by the Allegro PCB Manufacturing Option, OrCAD Documentation Editor, and OrCAD Panel Editor.

Allegro/OrCAD Starter Library

The Cadence Allegro/OrCAD Starter Library 1.0 is a free library that includes Allegro Design Entry HDL, Allegro Design Entry CIS, and OrCAD Capture schematic symbols along with Allegro/OrCAD PCB Editor footprints and the necessary component properties. It is designed for new customers who are evaluating or implementing a Cadence PCB flow or wanting to build a fully compatible library for use with the Allegro or OrCAD family of PCB design tools. A documented catalog of the Allegro/OrCAD Starter Library contents, as well as sample specifications used in the development of the library, is available in Adobe .pdf format.

This "starter" or baseline library is provided free of charge for use with Allegro Design Entry HDL, OrCAD Capture, Allegro Design Entry CIS, and Allegro/OrCAD PCB Editor. It can be used “out of the box” or as a template from which customized parts can be created. The library is provided as a zipped archive, with installation and usage instructions included.

Allegro PCB SI Cross-Section Library Extension

The Cadence Allegro PCB SI Cross-Section Library Extension is a free download that extends the library of cross sections available on the release media. With this library extension, users of the 2D full-wave field solver will have access to increased numbers of pre-solved cross sections that will speed the time to solutions while using Allegro Signal Integrity (SI) products. This algorithm-based integrated model library (ABIML) provides solutions to cross sections using multiple-surface roughness algorithms and highly increases the likelihood of a match of cross sections in PCB and package designs that can be used by the Allegro SI tools to shorten the time to a full-wave 2D interconnect model that can be used in SI simulation.
