Circuit elements in lumped parameters circuits are connected at nodes. Identification of circuit nodes will be extremely important to us when we are creating and analyzing circuits. Every node has a single unique voltage, so there can be no voltage drops (and thus no circuit elements) within a node. Perfect conductors do not cause voltage drops, so a node can contain perfect conductors.

Circuit elements are commonly categorized as either passive or active. A circuit element is passive if the total amount of energy it delivers to the rest of the circuit (over all time) is non-positive. (Passive elements can temporarily deliver energy to a circuit, but only if the energy was previously stored in the passive element by the circuit.) An active circuit element has the ability to create and provide power to a circuit from mechanisms external to the circuit.

Passive Sign Convention
When creating an electrical circuit, the fundamental goal is to apply voltages to the circuit such that the current is directed to perform some useful task. In order to do this, it is absolutely necessary to keep track of the voltage polarity relative to the current direction. he sign convention used by electrical engineers is the passive sign convention—so called since it applies to passive circuit elements.

Understanding Nodes in a Circuit
Kirchhoff's current law and Kirchhoff's voltage law are the basis for analysis of lumped parameter circuits. These laws, together with the voltage-current characteristics of the circuit elements in the system, provide us with the ability to perform a systematic analysis of any electrical network. Kirchhoff's current law (commonly abbreviated in these exercises as KCL) states: The algebraic sum of all currents entering (or leaving) a node is zero.

Understanding Loops in a Circuit
KVL depends upon the concept of a loop. A loop is any closed path through the circuit which encounters no node more than once. Essentially, to create a loop, start at any node in the circuit and trace a path through the circuit until you get back to your original node.

Project 3: Guess the Logic
In this project, you will download a bit file to your board to configure the FPGA with four different logic circuits. The circuits use buttons and switches for inputs, and LEDs for outputs. You must probe the logic circuits by applying all possible combinations of input signals. From the results of applying all possible combinations you will be able to write logic equations that describe the circuits' behaviors. You will then rewrite the equations using Verilog HDL and re-implement them on FPGA and compare the circuit behavior with the given bit-file.

Project 4: Majority of Five
How could you find a majority of the vote if each voter of five has a switch to vote for yes or no? The logic is fairly simple and will be used in this project. Any time there are three or more of the five who vote yes, then there is a majority and the LED needs to turn on.
