What is Altium Designer? Modules, integrations and alternatives
Altium Designer is an electronic design automation (EDA) application for schematic capture, PCB layout, library management and manufacturing output. It is widely used by product teams and design services that move boards from concept to fabrication and assembly. It is typically paired with a cloud workspace for sharing designs, components and BOM data.
Also known as: Altium, Altium PCB design, Altium 365
Altium Designer combines schematic entry, constraint-driven PCB layout, 3D board visualisation, rigid-flex support, and generation of fabrication and assembly outputs in one desktop environment. The design database ties components to symbols, footprints, 3D models and supplier data, so a part chosen in the schematic carries its manufacturing attributes through to the bill of materials.
The typical user is an electronics product company, an engineering services firm, or an EMS provider's engineering group. Teams range from a single engineer designing a sensor board to organisations with controlled libraries, review workflows and formal release processes. Altium also sells a cloud platform (Altium 365) that adds shared workspaces, versioned design data, component management and commenting for reviewers outside the EDA tool.
In a manufacturing stack, Altium sits upstream of ERP, MES and PLM. It produces the released design package (Gerber or ODB++, IPC-2581, pick-and-place data, BOM, drawings) and the item master seeds that purchasing and production planning consume. The quality of that hand-off depends on how disciplined the component library and BOM release process are, which is where many downstream ERP data problems begin.
Modules and capabilities
Schematic capture
Hierarchical and multi-sheet schematic entry with design rules, annotation and cross-probing into the layout.
PCB layout
Constraint-driven placement and routing, differential pairs, length tuning, layer stack management and rigid-flex stackups.
3D and MCAD co-design
3D board view with STEP import and export, and a collaboration path with mechanical CAD for enclosure fit.
Component and library management
Managed libraries linking symbols, footprints, 3D models and supplier parametric data to part numbers.
BOM management
Live bill of materials with supplier lookups, lifecycle information and release to downstream systems.
Manufacturing outputs
Gerber, ODB++, IPC-2581, drill files, assembly drawings and pick-and-place data for the fabricator and assembler.
Draftsman and documentation
Automated fabrication and assembly drawings generated from the board design.
Design review and versioning
Cloud workspace features for versioned projects, commenting and release of design data.
Integrations and data access
Fabrication and assembly outputs
Generates Gerber, ODB++, IPC-2581, NC drill, pick-and-place and BOM files consumed by PCB fabricators and assembly houses.
Mechanical CAD
Exchanges board and enclosure geometry through STEP, with plug-ins or collaboration links for common MCAD tools.
PLM and ERP
Releases BOM data to PLM or ERP through exports, APIs or connectors; the exact path varies by PLM product and edition.
Supplier data
Looks up part availability, parametrics and lifecycle status from supplier and aggregator databases during design.
Version control
Design projects can be versioned in the vendor workspace or placed under common version control systems.
Scripting and automation
Offers scripting and an extension interface for automating repetitive layout, report or export tasks.
Strengths
- Single environment covering schematic, layout, library and output generation lowers tool-switching overhead.
- Approachable for small teams, with a gentler learning curve than many enterprise EDA suites.
- Component management tied to supplier data helps catch obsolete or unavailable parts early.
- Good 3D visualisation and MCAD exchange for enclosure fit checks.
- Cloud workspace makes design review possible for people who do not run the EDA tool.
Limitations
- Very large multi-board systems and high-speed designs may need deeper simulation and constraint tools than the core product provides.
- Windows-centric desktop application; teams on other operating systems need virtualisation or a different tool.
- Library and BOM discipline is entirely the customer's responsibility; the tool does not fix inconsistent part numbering.
- Enterprise-grade PLM integration usually needs additional configuration or services.
Where AI helps Altium Designer users
- - Checking a BOM against the ERP item master to flag part numbers that differ in description, manufacturer or lifecycle state.
- - Summarising design review comments and ECO impact for planners who need to know which open work orders are affected.
- - Drafting component library entries from datasheets for human review before they enter the managed library.
- - Answering questions such as which released boards use a given obsolete component by querying exported BOM data on-prem.
- - Comparing two board revisions and generating a plain-language change summary for purchasing and production.
Evaluating Altium Designer? Check these
- Decide early how released BOMs reach ERP or PLM; test one real board through the full hand-off before committing.
- Audit your existing library quality, since migrating messy parts into a managed library multiplies the cleanup effort.
- Check whether your fabricator and assembler accept ODB++ or IPC-2581 so you can avoid ambiguous Gerber packages.
- Evaluate whether you need simulation for signal and power integrity, and whether it is included or sold separately.
- Clarify licensing for cloud workspace use, especially if contractors or customers need access.
- Ask how data is stored and exported if your company restricts cloud storage of design IP.

Frequently asked questions
What is Altium Designer used for?
Altium Designer is used to draw schematics, lay out printed circuit boards, manage component libraries and generate the files a fabricator and assembler need. It covers the path from circuit concept to manufacturing outputs in one application, and teams often add a cloud workspace for sharing and release management.
Does Altium Designer integrate with ERP systems?
Not directly as a native ERP module. It exports BOMs and component data that can be loaded into ERP or PLM through files, APIs or connectors. How clean the result is depends on part numbering discipline and on how the integration maps manufacturer parts to your item master.
What file formats does Altium Designer export for manufacturing?
It commonly outputs Gerber, ODB++, IPC-2581, NC drill, pick-and-place and BOM files, plus STEP for mechanical exchange. Which format to send depends on your fabricator and assembler, so confirm their preferred package before release.
What are the main alternatives to Altium Designer?
Common alternatives include Cadence Allegro and OrCAD, Siemens Xpedition and PADS Professional, KiCad as an open-source option, and Autodesk Fusion Electronics. The right choice depends on design complexity, team size, existing PLM and whether you need advanced signal integrity analysis.
Can AI help with Altium design data?
AI is most useful around the design data rather than inside layout itself: comparing BOM revisions, flagging mismatches with the ERP item master, summarising ECO impact and answering questions over exported data. Running this on-prem keeps proprietary design files inside your network.
