DesignSpark PCB resulted from a collaboration between electronics distributor RS Components and EDA software developer 'Number One Systems', being a fork of their long- established EDA Easy-PC.^[1] Electronic design automation (EDA) software is a sub-class of computer-aided design (CAD) software.

Projects are used in DesignSpark PCB to organise design files. A project can have an unlimited number of schematic sheets and one PCB layout file.

DesignSpark PCB has a Schematic editor. Schematics are used to draw up circuit diagrams and connections. A given project can have multiple schematic sheets that together combine to form the complete design.

There are some useful third party libraries that can be added.

Schematics are translated to a PCB layout file with a PCB Wizard. A PCB layout editor is then used to refine the physical layout of the printed circuit board. A design may have several iterations before a finalised printed circuit board is passed for production.

DesignSpark PCB includes an auto-router which automatically places tracks between components on a PCB layout. Components can also be auto-placed.

DesignSpark PCB produces Gerber and Excellon drill files. These standard files are accepted by PCB fabrication companies and are used to build a printed circuit board.

DesignSpark PCB Pro was a paid upgrade from the free DesignSpark PCB software. It was aimed at professional electronic design engineers of SMEs with an expanded feature set compared to the free DesignSpark PCB software.^[3] It was discontinued in September 2022 ^[4] and its features were merged into DesignSpark PCB as part of paid subscription plans.^[5]

Background edit

DesignSpark PCB Pro also resulted from a collaboration between electronics distributor RS Components and EDA software developer 'WestDev Ltd'.

Features edit

DesignSpark PCB Pro includes specialised tools to aid professionals with customising and managing large projects involving multi-layer PCBs. Noteworthy features referred to on the developer's website include:^[6]

• Blind and Buried Vias - to connect between different layers of a complex printed circuit board
• Fully configurable design rules editor and checker - to verify a circuit design and pass quality checks for production
• Hierarchical Schematic Design - split multi-sheet schematics into building blocks to make them readable and manageable
• Panel design editor - visualise and manage assembly of finished PCB designs prior to manufacturing
• Variant Manager - to specify different design variants to meet global market requirements
• Automatic shape-based and gridless router
• Advanced routing modes – trunk routing for differential pairs and buses, pull tight, auto mitre, and auto neck tracks
• Dual screen support
• Cross-hatch copper pours, teardrops, bullet, and asymmetric pad shapes are supported.
