If no initial condition is given explicitly, it will be assumed to be zero (AC analysis) or will be calculated automatically from the operating-point data (transient analysis). As an example, we set an initial capacitor voltage of V0 for the netlist entry C1 of the following filter circuit: In[22]:= filter = Netlist[ {V1, {1, 0}, V1}, {R1, {1, 2}, R1}, {C1, {2, 0}, Value −> C1, InitialCondition −> V0} ] Out[22]= NetlistRaw, 3

V$2 ⩵⩵ 1 0 0 I$V1 0 C1 V0 V1 See Section 2.7.5 for a description of initial condition handling during equation setup. Model, Subcircuit The purpose of the Model and Subcircuit directives is to mark a netlist entry as being a reference to a device model or subcircuit definition. Chapter 2.3 deals with the details.
