Procrastinated submitting a board my implementing voltage divider and resistor ratio calculation in Horizon EDA… Instead of punching resistor values into a calculator, just selecting two resistors on the schematic now shows the ratio for various combinations right into the head-up display.

Clicking on the link pops up a small voltage divider calculator.

Screenshot of the Horizon EDA schematic editor. The schematic is the output side of a buck converter with a voltage divider connecting the output to the feedback pin. The voltage divider resistors are selected and the head-up display shows: Resistor ratio R204/(R202+R204) = 0.24194 R202/(R202+R204) = 0.75806 R202/R204 = 3.13333 R204/R202 = 0.31915 On top of the schematic, there's a window showing voltage divider calculations. It reads that the 0.8V feedback voltage results in 3.307V output voltage.
