A similar strategy may be adopted for the rate at which customers enter a bank. Through the introduction of this randomness, the results of a simulation may never be the same as a previous simulation. The results generated from a stochastic system are typically analyzed statistically in order to make conclusions regarding the behaviour of the system. Conversely, a deterministic simulation system incorporates absolutely no random behaviour whatsoever. As such, the simulation results for a given set of inputs will always be identical.
Simulations involving circuit behaviour are examples of deterministic systems.
Supplying high signals to both inputs of a 2-input NAND gate will always produce a low signal on the gate's output, regardless of where the gate is located in the circuit's design hierarchy or when the inputs are received by the gate. Although this report will focus primarily upon deterministic simulation systems, stochastic systems can also be simulated with modest modifications to the implementation.
