Professional Electronic Schematic Design
Schematic Capture Services for Electronic Product Development
U.S.-based schematic capture services for new electronic designs, existing-product revisions, hierarchical schematics, library development and preparation of complete design data for PCB layout.
Schematic Development
From product requirements to an organized electronic schematic
Schematic capture translates electrical requirements, component information and interface definitions into an organized design database that defines the electrical connectivity of the product.
911EDA provides schematic capture services for engineering teams developing new electronics, revising existing designs or preparing an approved electrical design for PCB layout.
Projects can include complete new schematic development, updates to existing schematics, hierarchical organization, component-library development, engineering changes, review documentation and delivery of applicable native source files.
Schematic capture can be provided as a focused assignment or as part of broader PCB design services that continue through placement, routing, verification and manufacturing release.
Schematic Capture Capabilities
Schematic design support for new designs, revisions and existing projects
The schematic database is developed around the electrical requirements, component data, project documentation and downstream PCB layout needs defined for the project.
Hierarchical Schematics
Large designs can be organized into functional blocks and hierarchical sheets to improve navigation, maintainability and design review.
Symbols & Libraries
Creation and review of schematic symbols, PCB footprints, component data and library elements required by the design.
Existing Schematic Revisions
Schematics can be updated for engineering changes, obsolete components, product revisions, connector changes and other defined modifications.
Connectivity & Documentation Review
Net connectivity, power structure, reference designators, hierarchy, annotations and project documentation can be reviewed before release.
PCB Layout Handoff
Completed schematic data can be prepared with the libraries, documentation, net information and design requirements needed for downstream PCB layout.
Organized Design Data
Hierarchy and library structure support complex electronic designs
As electronic products become more complex, schematic organization becomes increasingly important. Large flat schematics can be difficult to navigate, review and maintain.
Hierarchical schematic capture groups related circuitry into logical functional sections such as power, processing, memory, interfaces, sensors, analog circuitry and communications.
Consistent symbol and library data also helps maintain reliable pin assignments, component identification and the relationship between the schematic and PCB database.
Typical schematic organization may include
- System-level hierarchy
- Power architecture
- Processors and programmable logic
- Memory devices
- High-speed interfaces
- Analog and mixed-signal circuitry
- Switching-power sections
- RF circuitry
- Connectors and external interfaces
- Debug and programming interfaces
- Test points
- Mechanical or system references
Schematic Capture Workflow
A structured path from requirements to PCB layout handoff
Schematic development progresses through defined stages so component data, connectivity and project requirements can be reviewed before the design moves into PCB layout.
For a detailed explanation of the complete workflow, review our schematic capture process guide, covering requirements, hierarchy planning, library development, schematic capture, verification, engineering review and PCB layout handoff.
Project Workflow
Six stages of schematic capture and review
1. Requirements & Inputs
Available block diagrams, component information, interface definitions, mechanical requirements and design constraints are reviewed to establish the project inputs.
2. Symbol & Library Development
Required schematic symbols, footprints and component information are created or reviewed before they are incorporated into the design.
3. Hierarchical Schematic Capture
Circuitry is captured and organized into logical sheets and hierarchical functional blocks appropriate for the complexity of the design.
4. Connectivity & Power Review
Net connectivity, power rails, interfaces, component pins and applicable electrical relationships are reviewed before customer release.
5. Customer Review & Revisions
Review files are provided so identified changes can be incorporated and the schematic can reach an approved design state.
6. PCB Layout Handoff
Approved schematic data, applicable libraries, design requirements and supporting documentation are prepared for PCB placement and routing.
Review Before Layout
Resolving schematic questions before PCB layout can reduce downstream rework
Questions involving component data, connector assignments, power architecture, net classifications or interface requirements are easier to address before those decisions become embedded in component placement and routing.
The schematic should therefore reach an appropriate level of review before PCB layout begins. Changes can still occur later, but revisions made after placement or routing has progressed may require additional downstream design work.
For more information about how review checkpoints affect later design stages, see our staged PCB design approval process .
Project Inputs
What to provide for a schematic capture project
The exact information required depends on whether the project involves a new electronic design, an existing schematic revision or a partial design that is already in development.
A project can still be reviewed when some information is preliminary, but open requirements should be identified so their effect on scope and schedule can be understood.
Useful project information
- System or product requirements
- Block diagrams
- Existing schematic files
- Bill of materials or component list
- Manufacturer part numbers
- Component datasheets
- Interface definitions
- Power requirements
- Mechanical information
- Existing component libraries
- Design standards or constraints
- Required EDA platform
- Expected deliverables
- Target schedule
Existing Designs
Schematic revisions and engineering changes
Schematic capture assignments do not need to begin with a completely new design. Existing projects can be revised when product requirements, component availability or engineering decisions change.
Work can range from a targeted component or connector change to a broader revision involving multiple schematic sheets, libraries and corresponding PCB changes.
When an engineering change also affects placement or routing, 911EDA can coordinate the schematic update with the associated PCB layout revision.
Typical revision requirements
- Obsolete component replacement
- Alternate component implementation
- Connector changes
- Power architecture changes
- Interface revisions
- Product feature updates
- Reference-designator updates
- Library corrections
- Hierarchy cleanup
- Documentation changes
Native Design Data
Editable source files delivered with the project
Applicable native schematic files and project libraries are returned at project completion so the customer can maintain, revise and reuse the design.
Deliverables are defined during project review and can include native schematic source files, PDF schematics, component libraries, net information, revision documentation and other agreed design files.
911EDA supports major electronic design platforms. Review the PCB design tools page for additional information about supported EDA environments.
