Efficient Inductance Extraction with Clarity 3D Layout

Are you struggling with inductance extraction for your complex IC package and PCB designs? Look no further! This post highlights the latest Clarity 3D Layout v2024.1 workflow for inductance extraction, providing a fast and accurate solution for inductance extraction and SPICE RLCG extraction using the Quasi-Static Solver.

Introducing Clarity 3D Layout Inductance Extraction

The new Inductance Extraction workflow in Clarity 3D Layout provides Quasi-Static-Solver-based RLCG extraction without the need to predefine ports for the source/sink. This means you can create source/sink automatically based on selected components or manually based on nodes on traces/shapes.

Key Features and Benefits

• Fast and accurate inductance extraction and SPICE RLCG extraction
• No need to predefine ports for the source/sink
• Automatic source/sink creation based on selected components or manual creation based on nodes on traces/shapes
• Supports complex 3D structures with adaptive FEM refinement technology
• Reduces simulation time with parallelization technology

Results

After running the inductance extraction flow, you can view the inductance summary results by selecting the L Full Matrix option on the workflow pane. The results are displayed for a frequency of 1 KHz, and you can export the results to a .csv file. The resulting L matrix shows the self-inductance values on the diagonal and mutual inductance values on the non-diagonal terms.

You can also generate a SPICE model from the R/L/G/C results, which can be used by other tools.

Lastly, you can plot the R/L/C/G values against frequency using the R/L/C/G vs Freq option on the workflow pane.

The resulting plots showed the frequency-dependent behavior of the inductance, resistance, capacitance, and conductance values.

Conclusion

Clarity 3D Layout Inductance Extraction is a powerful tool for efficient and accurate inductance extraction and SPICE RLCG extraction. With its Quasi-Static Solver and automatic source/sink creation, it streamlines the simulation process and reduces simulation time. Try it out today and experience the benefits of fast and accurate inductance extraction for your complex IC package and PCB designs!
