Engineers can use Multisim to build circuit schematics interactively and simulate circ uits.Multisim refinesthe complexity of spice simulations sothat engineers can quickl y capture, simulate, and analyze new designs without having to understand spice tech nology,making them more suitedto electronics education.Through Multisim and virt ual instrumentation technology,PCB design engineers and electronics educators can c omplete a comprehensive design process from theory to schematic drawing capture an d simulationtoprototypedesign andtesting. 3 Part A — Water Level Alarm System With Thermostat 1.DesignRequirement It isrequired to design awater level alarm system that can beusedtomonitor the river(s) water level and water temp
