Common Mistakes to Avoid
Several recurring pitfalls come from choosing the wrong simulation paradigm, underestimating model setup complexity, or assuming circuit-only results match physical behavior.
Choosing a system modeling tool when the requirement is circuit-level SPICE accuracy
NI LabVIEW and MATLAB Simulink excel at analog-style signal pipelines and continuous-time system modeling, but they are not dedicated analog circuit simulators for SPICE-level component accuracy. Teams needing transistor-level nonlinear device behavior should prioritize NI Multisim, PSpice, or Cadence OrCAD PSpice.
Under-planning for RF nonlinear analysis setup complexity
Advanced RF simulations in Keysight ADS require careful configuration, so RF teams should plan setup time for harmonic balance studies. For designs that do not require RF nonlinear steady-state tone control, NI Multisim or PSpice avoids RF-specific workflow overhead.
Assuming circuit simulation alone covers interconnect and electromagnetic effects
Ansys Electronics Desktop is designed to correlate circuit simulation with EM extraction using Maxwell-based field extraction.
