Скачать или смотреть What is the MS Debug Functionality in SimVision?

Master SimVision MS Debug for analog and mixed signal simulations. Explore Spectre netlists, track current flow, and debug connect modules in a unified GUI flow.

The Unified Mixed Signal Debugging Environment In modern semiconductor design, the gap between analog and digital domains is where the most complex bugs reside.
SimVision MS Debug is the solution specifically engineered to bridge this divide.

By extending the familiar SimVision GUI to the Analog Mixed Signal (AMS) domain, Cadence provides a comprehensive environment to explore Spectre netlists in a schematic view and track signal behavior across the Mixed Signal Boundary.

Technical Deep Dive: The MS Debug Toolset The power of the MS Debug option lies in its specialized browser integration :

• Design Browser: View the complete mixed signal hierarchy, allowing for seamless navigation between digital RTL and analog Spectre components.

• Source Browser: Analyze Spectre source files alongside digital code. This is essential for debugging Connect Modules, which are the critical interfaces between discrete and continuous time domains.

• Schematic Tracer: A powerful tool for traversing the hierarchy to browse terminal currents and track current flow at any specific point in the simulation.

• Mixnet Browser: Get granular data on connect modules, including parameter values and insertion indicators, ensuring that signal conversion is occurring correctly.

Frequently asked questions for Engineers :

1. What is the SimVision MS debug option?

→ It is a fully extended GUI functionality for SimVision that allows for deep debugging of analog and mixed signal simulations, supporting both GUI-based and command-line flows.

2. Can you view Spectre netlists in SimVision?

→ Yes, using the MS Debug option, users can explore and view Spectre netlists directly in a schematic view for better visualization of the analog portion of a design.

3. How do you track current in a mixed signal simulation?

→ The Schematic Tracer within SimVision MS allows engineers to traverse the hierarchy and browse terminal currents in real-time during the simulation process.

Logic Breakdown: The AMS Debugging Workflow

1. Initialization: Invoke SimVision with the MS Debug option enabled via command line or GUI.

2. Exploration: Use the Design Browser to identify the mixed signal boundary.

3. Visualization: Open the Schematic View to see the Spectre netlist representation.

4. Interface Check: Use the Mixnet Browser to verify that Connect Modules are properly inserted with the correct parameters.

5. Trace: Utilize the Schematic Tracer to follow the current flow from analog blocks into digital logic.
