You use the nodeset statement in the analog simulation control file to supply estimates of solutions that aid convergence or bias the simulation towards a given solution. You can use nodesets to provide an initial condition calculation for the transient analysis. The nodeset statement has the following format:
nodeset signalName=value …
Values you can supply with the nodeset statement include voltages on topological nodes, including internal nodes, and currents through voltage sources, inductors, switches, transformers, N-ports, and transmission lines.
For example,
nodeset Voff=0 X3.n7=2.5 M1:int_d=3.5 L1:1=1u
sets the following solution estimates:
- The voltage of node
Voffis set to 0.
- The voltage of node
- Node
n7of subcircuitX3is set to 2.5 V.
- Node
- The internal drain node of component
M1is set to 3.5 V.
- The internal drain node of component
- The current for inductor
L1is set to 1μ.
- The current for inductor
