Verifying Design Integrity Before Simulation: Pre-Simulation Validation

Before running simulations, it's essential to ensure that your design as well as the overall simulation set up is accurate, complete, and consistent. Pre-simulation validation is a critical step in the design flow that helps you identify and fix potential issues early on, saving time and resources.

What is Pre-Simulation Validation?

Pre-simulation validation is a process that checks your design for errors, inconsistencies, and potential problems that could affect simulation results or even prevent simulation from running altogether. This step helps you verify that your design is correct, complete, and ready for simulation.

Why is Pre-Simulation Validation Important?

Performing pre-simulation validation helps you:

1. Catch errors early: Identify and fix design errors, such as Spice syntax errors, connectivity issues, or incorrect component values, before simulation.
2. Ensure design consistency: Verify that your design is consistent across all levels of hierarchy and that all components are properly connected.
3. Improve simulation efficiency: By fixing issues before simulation, you can reduce the risk of simulation failures or incorrect results, saving time and resources.
4. Enhance design reliability: Pre-simulation validation helps ensure that your design is reliable and functions as intended, reducing the risk of costly rework or redesign.

The reason is Pre-simulation Validation also check set up consistency, for example, In clarity 3D Workbench:

1. a) If the Solution frequency is less than Freq Max/2 the tool will display a warning
2. b) If the set up include Wave ports and you want to extract low frequency points, the tool will tell you that if is not possible while using Waveports and that interpolation will be used instead.
3. c) More examples: no port defined, no boundary conditions defined, etc

How to Perform Pre-Simulation Validation

To perform pre-simulation validation, you can the below option:

By performing pre-simulation validation, you can ensure that your design is accurate, complete, and ready for simulation, saving time and resources in the long run.
