Cadstar 2021: The Streamlined PCB Design Solution for Professional Engineers

Cadstar 2021 is a comprehensive, mid-range electronic design automation (EDA) software suite from Zuken, tailored for engineers and designers who need a powerful yet manageable tool for creating complex printed circuit boards (PCBs). It provides a well-integrated, end-to-end workflow from initial concept and schematic capture through to final physical layout, design rule checking, and manufacturing file generation. Balancing advanced functionality with a user-friendly interface, Cadstar 2021 is designed to boost productivity for small to medium-sized design teams and individual engineers across various industries, from consumer electronics to industrial controls.

Core Philosophy: Integrated Workflow for Rapid Design Realization
Cadstar’s strength lies in its cohesive environment, where the schematic and PCB layout are dynamically linked. Changes in one domain are efficiently synchronized with the other, ensuring design integrity and reducing manual errors. This integrated approach, combined with strong design rule management, helps engineers navigate the complexities of modern PCB design—including high-speed constraints, dense component placement, and rigorous manufacturing requirements—within a single, streamlined platform.

Key Modules & Functional Capabilities:

1. Schematic Design & Capture

  • Hierarchical Schematic Entry: Supports top-down and bottom-up design methodologies for managing complex circuits across multiple sheets.

  • Intelligent Component Management: Centralized libraries manage schematic symbols, PCB footprints, and simulation models, ensuring consistency.

  • Design Rule Setup: Allows early definition of electrical and physical constraints (net classes, clearances) that carry forward into the layout phase.

2. PCB Layout & Routing

  • Interactive Placement & Editing: Advanced tools for component placement, including alignment, distribution, and real-time design rule checking (DRC) to prevent violations.

  • Manual & Assisted Routing: Provides full control over trace routing with intelligent interactive routing that honors design rules. The Design Expert advisor offers real-time guidance on optimal routing paths.

  • BlazeRouter Power Option: Includes an advanced gridless autorouter capable of handling complex, high-density boards with multiple signal layers, significantly reducing routing time.

3. Signal Integrity & High-Speed Design Support

  • Constraint-Driven Design: A robust constraint manager allows precise definition of timing, topology, and differential pair rules for critical high-speed nets (e.g., DDR memory, PCIe, Ethernet).

  • Integrated Signal Integrity Analysis (Optional): Can interface with simulation engines to analyze reflections, crosstalk, and timing delays before board fabrication.

4. Design Verification & Manufacturing Output

  • Comprehensive Design Rule Checking (DRC): Performs extensive checks for electrical, physical, and manufacturing constraints, ensuring the design is both functional and fabricable.

  • Manufacturing Output Generation: Automatically generates all necessary files for fabrication and assembly, including Gerber (RS-274X), NC Drill, pick-and-place, and bill of materials (BOM) reports.

  • 3D Visualization & MCAD Integration: A built-in 3D viewer allows engineers to check component clearance and fit within mechanical enclosures, and supports export for full MCAD integration.
