Electronic design automation (EDA) software constitutes a vital pillar within the technology product development landscape, enabling creation of intricate systems spanning across electrical, mechanical and software domains. As an electronic circuit board layout remains core to system function, selecting an EDA tool with robust printed circuit board (PCB) focus proves essential. Two longstanding market leaders in the PCB design tool arena include Altium Designer and Cadence OrCAD. Weighing the distinctions between these solutions provides helpful perspective guiding appropriate adoption per use-case needs.
Background on Altium Designer and OrCAD
Altium Designer manifests as a unified next-generation EDA platform built to streamline modern interconnected design processes. It leverages innovative architecture optimized for productivity when developing complex electronics spanning hardware circuits, PCBs, programmable logic implementations in FPGAs and the embedded software transforming those elements into functioning systems.
OrCAD constitutes a suite of EDA design applications provided by Cadence focused primarily on enabling robust PCB development capabilities. It integrates various point-tools for schematic capture, simulation, PCB layout/routing, library management and analysis traditionally associated with quality PCB design flows. The tools interoperate as a toolchain.
Both Altium Designer and OrCAD provide designers with capable feature-sets for realizing board implementations. However, several key factors give Altium Designer decisive advantages in numerous applications.
Factors Where Altium Designer Excels Over OrCAD
Examining core differentiators between Altium and OrCAD tools illustrates why the Altium design methodology better serves emerging needs:
Unified Design Environment
Altium links electrical/PCB design stages with FPGA and embedded software development within a common interface. This unified methodology enables streamlined cross-domain development crucial for connected devices.
Native 3D PCB Modeling
Altium’s 3D visualization environment enables interactive routing/placement directly over a true 3D perspective of the board including bends in traces rather than limited 2D abstraction.
Advanced Routing Automation
Extensive routing autocompletion in Altium surpasses OrCAD including obstacle avoidance for traces, vias, differential pairs and buses reducing manual effort.
Fabrication Output Generation
Altium provides seamless, validated manufacturing file generation workflows superior to OrCAD including links for supply chain logistics, assembly and testing houses.
Simulation Integration
Tight integration of SPICE, IBIS and HDL simulation capabilities in Altium boost confidence in circuit operation prior to committing expensive fabrication through virtually stressing key links.
Scripting & Extensibility
Altium allows easily customizing toolflows and automating repetitive tasks through scripting while also supporting accessibility needs leveraging the underlying data model.
Typical Applications Favoring Altium over OrCAD
The strengths above directly manifest benefits when applying the tools towards particular applications including:
Complex Mixed-Signal Boards
Unified simulations, high-speed routing tools, manufacturability checks in Altium facilitate multilayer analog/digital blends otherwise highly challenging to OrCAD point flows.
Multi-Domain IoT Edge Devices
Altium’s capacity to refine electrical, embedded software and FPGA facets in concert shortens interconnected system development cycles beyond OrCAD scope.
Advanced Driver-Assisted Vehicles
Functional safety requirements demand firmware verification only feasible through Altium’s unique cohesive methodology linking hardware behaviors with software testbenches.
AI Edge Accelerator Design
Leveraging Altium’s integrated co-design environment to model compute architectures realizing edge devices with ML hardware accelerators speeds time-to-market.
For conventional rigid PCB solutions, OrCAD remains capable. But moreover, Altium Designer’s unified design platform paradigm brings next-generation advantages as electronic systems grow vastly more sophisticated.
The Partner Ecosystem Difference
Supplementary to the tool capabilities directly, Altium maintains a vastly larger partner ecosystem comprised of complementary electronics design service bureaus, manufacturers and part suppliers. This allows organizations leveraging Altium Designer to engage a global community matching needs to solutions spanning the product realization timeline. Access to technical skills, manufacturing logistics and extended component sourcing facilitates innovation.
In summary, while both PCB design environments offer functionality, Altium Designer’s tighter integration, superior interfaces and access to ancillary support collectively help develop devices better, faster and more cost-effectively. Tool selection marks a crucial productivity determinant.
Making Informed PCB Design Tool Choices: FAQs
Q: What most distinguishes the Altium tool philosophy from OrCAD?
A: Altium fundamentally connects domains in a unified design environment rather than siloed point-tools. This methodology mirrors and accelerates sophisticated multi-technology product realization.
Q: Can OrCAD tools compensate shortcomings through add-ons?
A: Add-ons grafted onto legacy toolchains fail capturing innate interoperability and data model alignment crucial for productivity when iterating across domains during complex designs.
Q: What software innovations likely encourage OrCAD evolution?
A: OrCAD will further embrace 3D PCB visualization, simulation integration, manufacturing automation and cross-domain collaboration capabilities already proven in Altium advancing state-of-art functionality.
Q: How might FPGA design tool and OrCAD PCB tool synergies manifest?
A: Close FPGA-PCB co-design and co-verification within a common design environment will grow crucial as programmable logic gets embedded alongside circuits to meet solution demands with responsiveness.
Q: Does the partner ecosystem influence EDA tool selection?
A: Absolutely. An extensive manufacturer/supplier ecosystem boosts sourcing flexibility and technical support while aligning on preferable design tools reduces friction when collaborating across organizations during product development.
