20-sim

According to Ledin, "20-sim differs from other simulation tools like Simulink and Vissim in that it supports four methods for modeling dynamic systems: iconic diagrams, block diagrams, bond graphs and equations. This allows for example, the construction of electrical circuit simulations using standard symbols to represent components, such as op-amps and capacitors."
