EM Co-Simulation with Measurement-Based Models Leads to First-Pass Design Success (.PDF Download)

When simulating high-frequency filters with discrete passive components, it’s important to consider several factors to achieve simulation results that correspond to actual measured performance. One such aspect is the metallization that connects components together, as these metal interconnects impact the overall filter performance. In addition, component parasitics should be incorporated into a simulation to ensure that the simulated results accurately predict the filter’s response.

Fortunately, electromagnetic (EM) simulation software, such as Sonnet Suites from Sonnet Software, makes it possible to incorporate metal interconnects into a simulation. However, EM simulations that include ideal passive-component models often expose a discrepancy between simulated and measured performance, because ideal component models don’t account for the parasitics that are present in real-world parts.
