Report: Cadence OrCAD and Allegro 22.1 (Full)

Overview

Cadence OrCAD and Allegro 22.1 are electronic design automation (EDA) tool suites for PCB capture, schematic design, simulation, PCB layout, and advanced physical implementation. OrCAD typically targets schematic capture and entry, simulation (PSpice), and smaller PCB workflows; Allegro provides high-end PCB layout, signal/power integrity, and complex multi-board/system-level features.

Advanced High-Speed Design: Features included in the professional/high-tier suites (often Allegro) include complex constraint management, length matching, and differential pair routing.

The "221 Full" combination means a unified database. A schematic drawn in OrCAD Capture 221 can be directly transferred to Allegro PCB Editor 221 without netlist conversion errors.

What’s New in 22.1?

1. Constraint Manager Overhaul

The Constraint Manager received a modernized interface in 22.1. Electrical constraint sets (propagation delays, differential pairs, relative propagation delay) are now easier to visualize and debug. The new spreadsheet-style filtering allows engineers to isolate high-speed nets without scrolling through thousands of rows.

The 23.1 engine features a revamped DRC system that runs in the background with almost zero latency. This "correct-by-construction" approach prevents errors before they happen, significantly reducing the time spent in the "cleanup" phase of a project. 4. Why Upgrade to the Full 23.1 Suite?
