❓ Frequently Asked Questions
What is SPICE and why is it used in EDA?
SPICE (Simulation Program with Integrated Circuit Emphasis) is a circuit simulator used to model analog/mixed-signal circuits. It predicts voltages, currents and timing under DC, AC, and transient conditions to catch design issues before prototyping.
What is PCB CAD and why is it important in PCB design?
PCB CAD refers to computer-aided design software for creating schematic diagrams and PCB layouts. It automates netlists, component placement, routing, and design-rule checks to ensure the board is manufacturable and functions as intended.
How do oscilloscopes help when testing circuits?
An oscilloscope displays how a signal varies over time, showing waveform shape, amplitude, frequency, timing, and noise. It’s essential for debugging, timing analysis, and validating signal integrity.
How do SPICE simulations and PCB CAD work together in the design flow?
SPICE validates the circuit behavior at the schematic level, while PCB CAD translates that circuit into a manufacturable board layout. Using both helps ensure the design behaves correctly before fabrication.
