CADSTAR Schematics

CADSTAR SchematicsCADSTAR Schematics is a highly integrated front-end solution, providing a smooth and error-free transition (forward & back annotation) between schematics and PCB, easy to learn and use for both occasional and frequent users that provides a fast and efficient way of capturing electronic design intent, rules and constraints for smooth and error-free transition to PCB layout.

Top features and benefits

  • Easy to use, with intuitive user interface common to all CADSTAR programs
  • Integrated environment allows design changes to be efficiently transferred between applications
  • Access online library of 250,000 parts to reduce time in library development
  • Design tree view simplifies management of multiple circuit instances and other design data
  • Meet high-speed performance requirements with integrated constraint management system
  • Save time with reuse of known-good circuits from reuse library or from other designs
  • Define placement of critical components to optimize board performance early in the design process with Placement Planner
  • Powerful part selection features to support both graphical and parametric search engines
  • Complete support of design variants, including display control for accurate documentation
  • Improve implementation time with design import support from other layout systems such as Orcad, PCAD, Protel and PADS.

Data integrity and organization

Key to the success of the CADSTAR suite is the unified and cohesive environment that ensures data integrity throughout the design flow, so you can be sure the logical connections, components, and constraints you add in Schematic Capture will be present in the finished PCB layout.

Organize your design as a flat or hierarchical circuit, or apply both methodologies to meet your design and documentation process. Configurable design templates let you control the work environment for your engineering team, while still allowing individual users to customize their workspace.

Schematic Capture

CADSTAR Schematic Capture regularly checks your design to maintain the integrity of the netlist, ensures reference designators are unique, and verifies that components are up to date. Version control of both symbols and parts ensures your design is up to date with the latest library changes.

Speed and accuracy

Work smarter and faster by reusing your existing design data, or even import it from another system using the Design Migration tool.

CADSTAR Schematic CaptureCopy and paste design blocks, entire sheets, or just individual parts from another design, or use known-good logical and physical circuits with design reuse. Adding variants can also maximize the potential of your product in different markets by denoting non-fitted or alternate parts.

Definition of rules and constraints

In addition to track width, net class and spacing class (special spacing rules) you can assign a wide range of constraints to drive the CADSTAR High-Speed Design, Signal Integrity Verify and Power Integrity Advance tools with the Constraint Browser.

Generating outputs

Schematic Capture can generate intelligent PDF, bill of materials (BOM) and other standard format outputs, or any custom format using the built-in Report Generator. Netlist data, including Spice format and pinlist files for FPGA integration, can also be exported to third party tools. You can also add your own applications and integrate them with CADSTAR using the OLE toolkit.

Viewing and verification

CADSTAR PCB Design Software

Zone markers, combined with configurable net references, make tracking signals across a large design simple, while full cross-probing helps you locate and highlight items in any CADSTAR application including Schematic Capture, Constraint Browser, PCB Layout, Place & Route Editor, Signal Integrity Verify and Power Integrity Advance.

You can even share design data (Schematic and PCB Layout) with your colleagues and customers using the free CADSTAR Design Viewer.


CADSTAR Schematic Capture includes a library of ready-made parts and the Graphical Library Editor with symbol wizards. You can either define your own parts, select from the Zuken online library of over 250,000 parts, or use the SamacSys live library of free, high-quality PCB symbols and footprints for CADSTAR. Search, download and place parts directly from within CADSTAR by launching SamacSys Library Loader and Component Search Engine in the toolbar.

Attributes in the library help you search and maintain version control, track obsolescence, integrate links to datasheets and websites, and add custom fields as required. The Part library can be stored in any ODBC-compliant database, enabling integration with your engineering or MRP systems.

Optional Schematic Add-ons

CADSTAR Constraint Browser

Constraint Browser

As design constraints increase in complexity, CADSTAR Constraint Browser simplifies constraint management by providing a fast and effective method to enter the most complex of rules. The Constraint Browser guides engineers through a fully integrated, constraints-driven design methodology to meet high-speed performance requirements, reducing design costs and time-to-market by eliminating unnecessary prototypes and re-engineering cycles.

CADSTAR Placement Planner

Placement Planner

CADSTAR Placement Planner enables the engineer to engage the placement process during logical circuit design. As an add-on to CADSTAR Schematics, Placement Planner is intended to help electronic engineers communicate their intent and provide guidance to the PCB designer more effectively.

CADSTAR Constraint Browser

Variant Manager

The CADSTAR Variant tool allows the designer to change any parts to match all the different product and international requirements, storing all the information in the single CADSTAR PCB or Schematic design file.
