Virtuoso Studio: Schematic Syntax for Hierarchical Nodes and Buses in DeepProbe

In the ever-evolving world of analog design, efficiency and clarity are key. With the latest enhancements in analogLib's DeepProbe instance, designers can now leverage schematic syntax and bus format support to streamline their debugging and analysis workflows. This blog explores how these features simplify the design process and improve productivity.

Using Schematic Syntax for Hierarchical Nodes

One of the standout features in the updated DeepProbe instance is the ability to directly use schematic syntax when specifying hierarchical nodes. This means that instead of manually converting node names into Spectre-compatible syntax, designers can now:

• Type schematic paths directly, such as /I0/net4.
• Use the navigator tool to locate a net, right-click to select “Copy Path,” and paste it into the DeepProbe instance properties.

This schematic syntax is automatically translated into Spectre syntax during netlisting, eliminating the need for manual conversion and reducing the risk of errors. It’s a small change with a big impact—making hierarchical node management more intuitive and less error-prone.

Bus Format Support: A Game-Changer for Debugging

Another powerful addition is the support for bus formats in the DeepProbe instance. This feature allows designers to:

• Use buses directly in their DeepProbe configurations.
• Ensure bit-width consistency between the instance name and the hierarchical node (e.g., a 4-bit bus in the design must match a 4-bit bus in the DeepProbe instance).
• Benefit from separate line netlisting for each bus bit, which enhances readability and simplifies debugging.

This structured approach to bus handling makes it easier to trace signals and analyze complex designs, especially in large-scale analog systems.

So, if you haven’t explored these capabilities yet, now is the perfect time to integrate them into your workflow and elevate your analog design process.
