Full Guide – Design Electronics in SnapEDA (Step by Step)

Posted by

SnapEDA is a free, cloud-based design platform used by electronics engineers to research, design, and collaborate on printed circuit board (PCB) projects in one unified workspace.

The SnapEDA Editor tool allows interactively:

  • Creating schematics and layouts
  • Circuit simulation
  • PCB layout routing and 3D view
  • BOM generation and design sharing

An integrated component library contains over 500k manufacturer parts covering all needs from single board hobby projects to complex professional hardware products development in verticals spanning IoT, robotics, industrial automation and consumer electronics.

This step-by-step walkthrough covers end-to-end electronics product development workflow from concept to manufacturing outputs leveraging SnapEDA’s schematic capture, simulation, PCB layout and co-design capabilities tailored for the hardware community.

Getting Started

To start your first design project, simply:

  1. Go to SnapEDA website
  2. Sign up for a free account
  3. Click Create Design button to initialize blank project

The integrated browser-based SnapEDA Editor will launch taking you into schematic capture mode ready to start placing components. Tutorial pop-ups provide interactive guidance introducing primary areas and functions.

Let’s begin the electronics design process!

1. Schematic Capture

SnapEDA’s schematic editor provides traditional worksheet style canvas and wide range of drawing tools to create base schematics.

Below covers key concepts doing schematic entry:

Create Sheet

Grid buttons allow inserting A4 or Letter page sizes to start capture. Top toolbar shows page navigation between multiple sheets when design complexity builds up.

Add Components

From the left SnapEDA component browser showing 500k+ cataloged parts, select required devices and literally drag-drop symbols needed onto sheet. Repeat inserting parts until full bill-of-materials refines representing concept.

Draw Connectivity

Click wiring tool and trace connections between component pins to represent logical circuit connectivity flow. Visual cues indicate valid joins. Tap wire endpoints to cycle amongst available pin electrical types like input, output, passive etc.

Arrange and Annotate

Use alignment tools to neatly organize parts and wiresplaced. The Annotate button auto-sequences reference designators. Cross-probe highlighted nets between sheets using mouse overs.

Run Electrical Rules Check

Frequently validate connections integrity against missing pins and dangling wires using the built-in Electrical Rules Check (ERC). Fix reported issues incrementally as you build out complexity.

Add Details

Annotation tools allow documenting schematics with custom call outs, headings, error/warning markers and description boxes. Import images using drag and drop.

When ready, run final ERC to validate completion before saving prior to simulation or PCB layout conversion.

2. Simulation Setup

SnapEDA provides integrated circuit simulation capability to interactively verify logic operation right from within the Editor by placing probe pins, generating stimuli and inspecting node waveform behaviors to confirm functioning before committing expensive PCB prototype build cycles.

To setup simulation:

Attach Test Probes

From toolbar, choose Pin icons to drop Probe, Stimulus or GND pins onto nets needing inspection. Probes passively monitor signals, while Stimuli actively overrides to inject inputs.

Configure Simulation Models

For key ICs, right click instance to browse and attach simulation model to define behavioral logic. Standard model formats like Verilog, VHDL and SPICE supported.

For passives/discrete parts simulation abstraction auto-inferred from schematics.

Generate Stimulus

Click Stimulus pin and edit values waveform over time on popup. Define combinations to validate corner cases. Add more stimulus pins as needed to excite.

Run Simulation

The “lightning” icon triggers simulation solving. Probe pin waveforms display based on attached model logic and stimuli applied verifying operation before PCB layout routing.

Iteratively refine probes, models and stimuli while smoothly blending schematic design and simulation steps to finalize circuit performance meeting requirements using SnapEDA’s integrated electronics design environment.

3. PCB Layout

Upon schematics completion, click the PCB Layout icon to launch physical board layout canvas retaining all placed parts and connectivity.

Below outlines core concepts doing PCB layout within the SnapEDA editor:

Import Stackup

Start by defining layer count and materials. SnapEDA includes stackup templates for common fabrication processes and board types including FR4, Rigid-Flex, HDI and RF microwave.

Place Components

Parts from schematic get pre-imported ready for placement. Drag devices from left onto canvas and arrange based on grouping, size priority. Rotate and alignment aids assist interactive positioning.

Route Traces

Click Route Track to connect pads. Push and shove capability enables intelligent completion by dynamically nudging neighboring traces when dragging new connections through dense areas avoiding manual cleanup.

Validate Design Rule Checking

Set clearance rules and run Design Rule Checks (DRC) to validate spacing and constraints compliance between tracks/pads/vias. Errors highlight issues to address preserving manufacturability.

3D View and Emulation

Photorealistic 3D mode visualizes board and components providing mechanical fit verification through STEP export to external tools. Measure distance/clearance between objects directly by dimension lines. Pan, orbit and zoom controls aide inspection from all angles.

Copper Pour and Planes

Add copper pours/polygons for large fills tied to nets. The Auto-pour button automatically pours all remaining nets improving EMI control with entire area flooded. Split power and ground to separate polygons for isolation.

Output Manufacturing Files

When layout completes DRC clean, quickly generate industry standard CAM and documentation outputs including Gerber files, drill hits, assembly drawings, BOM and component placement centroid file for handoff.

Leverage SnapEDA’s unified EDA environment to smoothly link schematics into functional routed PCB layout ready for fabrication in minutes using cloud convenience from any OS without install headaches.

4. Co-Design and Team Collaboration

Once base design completes, leverage SnapEDA‘s real time collaboration features to securely interface with electronics manufacturing partners or ODMs through the cloud to streamline outsourcing production hand offs.

Below summarizes critical co-design capabilities improving supply chain interactivity:

Share Project Access

Under project settings, invite other SnapEDA users via email address to privately view or edit the design files in real time enabling distributed team cooperation reducing back and forths.

Comment and Annotate

Partners can place markers, annotations and comments on specific areas both on schematics and PCB layout layers needing attention improving clarity on potential DfM refinements needed without needing meetings.

Model Import

No EDA tool has all simulation models. Allow PCB partners to directly attach relevant IC behavior models under secured access improving model availability.

Engineering Change Order (ECO) Handoff

Managing iterations via ECO firmware is smoothed by graphical highlight tools to pinpoint redlines needed against latest PCB version accelerating identification of change point deltas.

By unifying design data access, communication and workflows between customer and suppliers within one platform, SnapEDA aims to bridge electronics hardware innovation barriers improving product development velocity from concept to certified production.

Final Files Export and PCB Ordering

Once design completes DRC verification through internal team review or external manufacturing partner inputs, export final data packs critical for procurement.

On editor top Toolbar, select Export Manufacturing Files containing:

  • Gerber – Full layer plot files for board fabrication
  • Drills – NC excelon drill hit table for machining
  • Centroid – XY pick and place program for SMT assembly
  • Drawings – PDF assembly drawings with callouts
  • 3D Model – Mechanical STEP model for enclosure design fit
