452 4. Appendix V1 node1 node2 An open-circuit branch is essentially the same as an independent current source with zero source current. The value specification is ignored. However, it should be set to 0 (zero) to reflect the fact that the source current is zero. Note that open circuits are mostly used implicitly as controlling branches of voltage-controlled sources but they may also be used explicitly in a netlist when a voltage meter is needed. In the latter case, modified nodal analysis employs a special matrix fill-in pattern which augments the vector of unknown node voltages by the branch voltage across the open circuit. This allows for directly computing the differential voltage between two nodes neither of which is ground. Without the voltage sensor, two node voltages would have to be solved for and then subtracted from one another, which would be computationally more expensive. 4.2.8 ShortCircuit type name syntax ShortCircuit {SCname, {node1, node2}, 0} denotes a short-circuit branch Circuit element type ShortCircuit. I1 node1 node2 A short-circuit branch is essentially the same as a voltage source with zero source voltage. The value specification is ignored. However, it should be set to 0 (zero) to reflect the fact that the source voltage is zero. Note that short circuits are mostly used implicitly as controlling branches of current-controlled sources. They may also be used explicitly as current meters in combination with modified nodal analysis.
4.2 Netlist Elements 453 4.2.9 CurrentSource type name syntax CurrentSource {Iname, {node+, node−}, value I0 } denotes an independent current source Circuit element type CurrentSource. node+ I0 The positive reference direction for the source current is from node+ to node−. 4.2.10 VoltageSource type name syntax VoltageSource {Vname, {node+, node−}, value V0 } denotes an independent voltage source Circuit element type VoltageSource. node+ V0 node- node- The positive reference direction for the source voltage as well as the current through the source is from node+ to node−.
