Discussion Overview
The discussion revolves around finding software that can accurately calculate the impedance of various geometrical shapes of traces at low frequencies, specifically between 1 - 20 kHz. Participants explore the challenges associated with existing tools and the nature of the impedance being investigated.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- One participant seeks software like Sonnet that performs well at low frequencies but notes that Sonnet's data is often unreliable in this range.
- Another participant points out that at low frequencies, lumped parameters are more relevant than distributed parameters, suggesting that impedance is influenced by lumped capacitance, inductance, and leakage.
- A participant clarifies that they are interested in calculating not just capacitance and inductance, but also resistance, and describes the impedance as a discrete one with a complex shape, making manual calculations challenging.
- A suggestion is made to consider Ansoft's EM simulation software, which has a free student version that might meet the original participant's needs.
Areas of Agreement / Disagreement
Participants express varying views on the appropriate software and methods for calculating impedance, indicating that multiple competing approaches and tools are being considered without a clear consensus on the best solution.
Contextual Notes
The discussion highlights the limitations of existing software at low frequencies and the complexity of the geometries involved, which may affect the accuracy of impedance calculations.
