EveryCircuit vs. Ansys Pharos

An animated circuit offers a level of informational depth that far surpasses a multitude of equations and charts combined. By layering animations of voltages, currents, and charges onto the circuit schematic, users can attain a deeper understanding of circuit operations. Tailored for high-speed performance and interactive engagement, the circuit simulation engine enables users to initiate simulations with a single click, accommodating a diverse array of components ranging from simple resistors and logic gates to complex transistor-level oscillators and mixed-signal systems. Throughout the simulation, users have the ability to adjust switches, tweak potentiometers, change LED current-limiting resistors, and incrementally raise input voltages, with the circuit dynamically reflecting these changes in real time. Unique mini-waveforms are displayed along the schematic wires, distinguishing between digital and analog signals, where continuous analog voltages are presented numerically while digital wires are color-coded to enhance clarity. Furthermore, users can visualize any two time-domain signals in XY mode, further enriching their analysis capabilities. The oscilloscope's scale and grid ticks automatically calibrate to optimal settings as the data varies, guaranteeing accuracy in measurement throughout the simulation. This interactive feedback loop not only makes the learning process enjoyable but also encourages users to explore the nuances of circuit behavior more thoroughly. Ultimately, the combination of real-time interactivity and visual representation fosters an environment where users can experiment and expand their knowledge of electronics effectively.

Pharos combines the outstanding electromagnetic (EM) engine capabilities of Ansys with a dedicated high-capacity circuit simulation engine to perform coupling analyses and evaluate potential EM crosstalk aggressors for each victim node. By pinpointing the most at-risk nets, designers can focus their efforts on reducing EM crosstalk in these vital connections, which helps minimize risks during the design phase. In addition, Pharos integrates a robust extraction engine alongside an internal simulation engine to carry out thorough EM analyses and rank potential aggressors in relation to each victim net. This feature allows designers to prioritize the most critical nets in their designs effectively. As the complexity of designs increases and the variety of magnetic field interference grows, the task of identifying all susceptible victim/aggressor net pairs becomes increasingly challenging, often approaching the realm of impossibility. Therefore, Pharos proves to be an essential resource, simplifying the management of EM issues in complex electronic designs while ultimately enhancing overall design quality and reliability.
