Altium Designer 25.2.1 Build 25 focuses on enhancing real-time collaboration, high-speed design efficiency, and advanced mechanical integration. This guide highlights the exclusive features and updates within the version 25 series. 1. Collaborative PCB CoDesign Version 25 introduces Real-Time Co-authoring , allowing multiple designers to work on the same PCB document simultaneously. Conflict Resolution CoDesign panel to view active collaborators and manage design changes in real-time. Version Tracking : Reviews and comments are tied directly to specific design versions to reduce handoff friction. 2. Advanced Constraint Management The updated Constraint Manager automates the management of high-speed design rules. Automated xNets : Automatically generates xNets for serial components based on pin configurations (supporting dual-inline and single-inline setups). Syntax Highlighting : Real-time detection and highlighting of syntactically incorrect custom query expressions within rules. 3. Integrated Harness & Multi-board Design Significant updates have been made to bridge the gap between electronics and mechanical routing. Inline Harness Connectors : Allows you to divide existing harness connections into two parts directly within the multi-board schematic editor. Manufacturing Workbooks : Export complete Excel Manufacturing Workbooks from harness projects, including BOMs, wiring lists, and assembly details. ECAD-MCAD Sync : Synchronize harness topology and physical wire lengths between Altium and MCAD tools without file conversions. 4. PCB Layout & Documentation Enhancements Layout Replication : Use the new PCB Layout Replication tool to duplicate complex routing and component placement patterns in seconds. Custom Pad Geometries donut-shaped pads and other custom geometries directly in the PCB editor to meet specific component stability requirements. IP Protection in ODB++ : Configure ODB++ output to restrict signal layer visibility or neutralize net names (e.g., "Net_1") to protect intellectual property. Vertical Pin Margins : Define custom vertical margins for pin designators and names at both global and local levels. 5. System & Performance Updates What’s New in Altium Designer
