SPICE modelling of electronic circuits
SPICE is an interpreted language consisting of a source file and an interpreter. SPICE source files are commonly referred to as netlists. In a netlist, we define nodes and the connections of components to these nodes. As an example, consider the simple resistive circuit shown in Figure 1.1 (File: sim1).
Figure 1.1 Example circuit
There are 4 nodes in the circuit. Node 0 is the ground, node 1 is the junction of R3 and R4, node 2 is the junction of R1, R2, and R3, and node 3 is the junction of the battery and R1. The netlist for this circuit is shown in Figure 1.2. sim1 (TINA Netlist Editor format) ************************************** **
