RC circuit Monte Carlo study

Recreated course exercise · Altium Designer, MixedSim

Recreated an Altium course exercise to explore component-tolerance effects in a loaded RC circuit. Compared simulated output-voltage traces using Gaussian, uniform, and Altium’s Worst Case Monte Carlo distributions.

Circuit

The course circuit uses a 500 Ω series resistor, a 7 µF shunt capacitor, and a 1 kΩ load. The schematic specifies a 100 Hz sinusoidal source with a 10 V offset and 10 V amplitude.

Simulation results

Each screenshot shows 30 labeled output-voltage traces over 0–30 ms. The overlays illustrate variation in the simulated response for the course setup.

Scope

This is a reproduced training exercise. The screenshots document simulation output; they do not establish measured hardware performance, manufacturing yield, or guaranteed worst-case limits.

The uploaded images do not include the component-tolerance settings or the complete simulation configuration. Altium’s Worst Case distribution randomly selects tolerance endpoints; these plots alone do not demonstrate exhaustive coverage of all combinations.
