CADSTAR for layout professionals

Introduction to CADSTAR Layout

CADSTAR is a powerful PCB design software tool used by layout professionals to create high-quality printed Circuit Board Designs efficiently. Developed by Zuken, CADSTAR offers an intuitive interface, advanced features, and seamless integration with other design tools to streamline the PCB layout process from concept to manufacturing.

Key Features of CADSTAR Layout

Schematic Capture: CADSTAR includes a schematic capture tool for creating electronic schematics that serve as the basis for PCB layout. It supports hierarchical design, multi-sheet schematics, and easy component placement.
constraint-driven Layout: CADSTAR’s constraint-driven layout ensures that your PCB design meets all electrical and manufacturing requirements. It allows you to define rules for component placement, routing, spacing, and more.
High-Speed Design: With increasing demands for faster data transfer rates, CADSTAR offers features specifically tailored for high-speed PCB design. It includes impedance control, length matching, differential pair routing, and signal integrity analysis.
3D Visualization: CADSTAR provides real-time 3D visualization of your PCB design, allowing you to inspect component placement, check for mechanical interferences, and ensure proper fit in the enclosure.
Manufacturing Output: CADSTAR generates comprehensive manufacturing output files, including Gerber files, drill files, pick and place data, and bill of materials (BOM), ensuring smooth transition to PCB fabrication and assembly.

Getting Started with CADSTAR Layout

System Requirements

Before installing CADSTAR, ensure that your computer meets the minimum system requirements:

Component	Minimum Requirement
Operating System	Windows 10 (64-bit)
Processor	Intel Core i5 or equivalent
RAM	8 GB
Graphics Card	Dedicated graphics card with 1 GB VRAM
Storage	10 GB free disk space

Installation Process

Download the CADSTAR installer from the Zuken website.
Run the installer and follow the on-screen instructions.
Choose the installation directory and select the components you want to install.
Agree to the license terms and click “Install”.
Once the installation is complete, launch CADSTAR from the desktop shortcut or start menu.

CADSTAR Layout Workflow

Creating a New Project

Open CADSTAR and click “File” > “New” > “Project”.
Enter a project name and select a location to save the project files.
Choose the template that best suits your design requirements (e.g., 2-layer, 4-layer, or custom).
Click “OK” to create the new project.

Importing Schematic Design

In CADSTAR, click “File” > “Import” > “Schematic”.
Browse and select the schematic file you want to import (e.g., .sch or .dsn).
Choose the appropriate import options and click “OK”.
The schematic will be imported into CADSTAR, and you can view it in the schematic editor.

Component Placement

Switch to the PCB layout editor in CADSTAR.
Use the “Place Component” tool to manually place components on the PCB.
CADSTAR also offers automatic component placement based on your defined rules and constraints.
Adjust component positions as needed to optimize layout and minimize signal path lengths.

Routing and Signal Integrity

Define the routing constraints, such as Track width, spacing, and via settings, in the “Constraints” dialog.
Use the “Route Track” tool to manually route the connections between components.
CADSTAR’s autorouter can automatically route the remaining connections based on your specified rules and constraints.
Perform signal integrity analysis to ensure optimal signal quality and minimize crosstalk and EMI.

Design Rule Checking (DRC)

Open the “Design Rule Check” dialog in CADSTAR.
Select the rules you want to check, such as clearance, spacing, and drill sizes.
Run the DRC to identify any design rule violations.
Review and address each violation to ensure your PCB layout complies with the manufacturing requirements.

Manufacturing Output Generation

Once your PCB layout is complete and passes the DRC, you can generate manufacturing output files.
Click “File” > “Fabrication Outputs” to open the output generation dialog.
Select the desired output formats, such as Gerber, drill, and pick and place files.
Configure the output settings, including layer mapping and file naming conventions.
Generate the output files and review them for accuracy before sending them to the PCB manufacturer.

Advanced CADSTAR Layout Techniques

Hierarchical Design

CADSTAR supports hierarchical design, allowing you to break down complex PCBs into smaller, manageable subdesigns. This approach simplifies the layout process and promotes reusability of common circuit blocks.

Create separate schematic and layout files for each subdesign.
Define the interfaces between subdesigns using hierarchical ports.
Assemble the subdesigns into a top-level schematic and layout.
Use the “Update Hierarchy” function to propagate changes from subdesigns to the top-level design.

Reusing Design Blocks

CADSTAR enables you to create reusable design blocks, such as power supply circuits or interface modules, which can be easily integrated into multiple projects.

Design and validate the reusable block in a separate project.
Save the block as a library component or subcircuit.
Import the reusable block into your main project using the “Place Component” or “Import Subcircuit” functions.
Connect the block to the rest of your design and adjust its placement as needed.

Variant Management

CADSTAR offers variant management capabilities to handle design variations efficiently. You can create multiple variants of a PCB layout with different component configurations or assembly options.

Define the base design with common components and layout.
Create variant-specific schematic and layout files for each variation.
Use the “Variant Manager” to specify the components and settings for each variant.
Generate manufacturing outputs for each variant separately.

Collaboration and Version Control

CADSTAR integrates with version control systems like Git or SVN to facilitate collaboration among design team members and track design revisions.

Set up a version control repository for your CADSTAR project.
Regularly commit your design changes to the repository.
Use branching and merging techniques to work on different design aspects concurrently.
Resolve conflicts and merge changes from multiple team members.
Tag specific design revisions for easy reference and retrieval.
