McCAD PCB-ST is a highly integrated printed circuit board (PCB) layout design environment tailored for engineers and board designers who require robust, professional-grade editing and automation tools. Developed by VAMP Inc., this netlist-driven application serves as a cornerstone of the McCAD Electronic Design Systems (E.D.S.) suite. It seamlessly bridges the gap between initial schematic capture and final hardware manufacturing by offering full forward and backward annotation alongside advanced design verification. Core Architecture and Integration
The software functions as an online database management system that links dynamically to McCAD Schematics. This tight cross-environment integration relies on an Engineering Change Order (ECO) manager.
Netlist-Driven Engine: Automatically syncs net and component attributes between schematics and layout.
Bi-directional Annotation: Simplifies design synchronization, making manual cross-checking a thing of the past.
Cross-Platform Availability: Versions are engineered to support legacy and modern operating systems including macOS and Microsoft Windows.
Workspace Scale: Supports dense hardware creation on surfaces expanding up to an engineering “E” size (34” x 44”). Intelligent Layout and Routing Options
Designing a complex board demands absolute precision. McCAD PCB-ST provides a database resolution of 0.001 inches, grid snap controls, and full metric unit flexibility to ensure precise component placement. Routing is highly flexible, supporting up to 16 distinct board layers.
The system features an internal, point-to-point low-level router designed specifically to assist analog engineers with meticulous line-by-line trace optimization. For advanced workflows, the software links directly into optional high-performance autorouting engines:
McCAD Tracker: A mid-level autorouter built for balanced trace distribution.
McCAD Trailblazer: A high-performance autorouter utilizing advanced “push and shove” technologies to route multilayer systems at high speeds. Advanced Automation and Production Safety
Errors during physical production are incredibly costly. To minimize human error, the software provides a suite of background automation tools that monitor constraints in real time:
Design Rule Checking (DRC): Automatically flags physical layout errors and netlist connection violations.
Thermal and Power Management: Features automated ground plane creation and automatic thermal dispersion.
Manufacturing Safeguards: Automates via insertion, interlayer item movement, and solder mask generation.
Component Libraries: Out of the box, the tool includes access to an online library editor along with an extensive database of more than 5,500 external device footprints. Manufacturing Outputs and Logistics
Once a layout passes inspection, the integrated Gerber Translator module converts the design into universally accepted, high-accuracy photo-plotting text files. Beyond standard Gerber files, the platform generates a comprehensive array of production scripts via its data extraction engine: McCAD PCB-ST Download – Integrated PCB layout design
