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.

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.

Copy 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

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 and 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.

Creating Topologies Using CADSTAR Schematics

Errors in collaboration are something that I’m focusing on quite a bit at the moment. Today I’m looking at the creation of topologies and error-prone collaboration between circuit designers and PCB designers when sharing constraints during the design process.

    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 highspeed performance requirements, reducing design costs and time-to-market by eliminating unnecessary prototypes and re-engineering cycles.

    The Constraint Browser provides an easy-to-use spreadsheet interface with constraint wizards to setup rules for applications, such as DDR2/DDR3/DDR4 memory interfaces. The Constraint Browser works with CADSTAR Schematic to help you reduce your design cycle time and ensure that your designs are completed to the correct specifications.

    Placement Planner

    Designed to work in conjunction with the CADSTAR SCM & PCB Design Editor allowing electronic engineers pre-placement, CADSTAR Placement Planner enables the engineer to engage the placement process during logical circuit design. Whether you are conducting placement studies for real estate planning or defining the location of critical components, Placement Planner helps improve your design flow between logical design and PCB layout.

    Placement Planner is an add-on to CADSTAR Schematics, and is intended to help electronic engineers communicate their intent and provide guidance to the PCB designer more effectively, without time-consuming iterations that can cause unnecessary delays.

    Variant Manager

    Allowing you to manage all the variants of a design for multiple product and international requirements, including storing all information in a single Schematic and PCB design file, each with its own Bill of Materials (BOM).

    As PCB designs become more sophisticated and the design cycles ever smaller, it is imperative that the PCB design can satisfy the global market place and the numerous product options.

    No longer is it economical to design one PCB for one product and one market. One PCB must satisfy many markets, with different safety and environment requirements and many different product variations.

    The CADSTAR Variant tool is designed to satisfy this requirement. It 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.
