Terminology for LABTerminology for LAB•Component: has one or more inputs and one or more outputs which take on discrete values•Combinational logic component: the output value depends present values of inputs•Sequential circuit component: the output values depend on present and the past input values. In other words the sequential component has memory

•a schematic is a design composed of a number of interconnected componentscomponents are connected together by wires or nets

a Symbol is used to create hierarchy. Symbol is viewed as a functional block and defined with a separate schematicpins are input or output signals of symbol
