CircuitNAV extends the capabilities of the standard SPICE circuit simulators, such as LTspice, Micro-Cap, TINA, and PSpice, by providing the algebraic or symbolic representations of circuit parameters. CircuitNAV uses the netlist file from the free SPICE simulation tools as the input, solves the system of equations in the background, and outputs the equations for each node and branch.

The current version of CircuitNAV supports the basic linear components: R, C, L, V, I, E (VCVS), G (VCCS), H (CCVS), F (CCCS).

The tool intends to facilitate your study, analysis, and design of circuits.
