"WebA singular matrix is a condition that arises when the system of mathematical equations describing the circuit has either no solution or an infinite number of solutions. This can occur as a result of round-off errors as the simulator attempts to solve the circuit, but more commonly it is a result of problems with the circuit configuration.
