170 2. Tutorial As a first step we import the numerical simulation data calculated with PSpice into Mathematica using ReadSimulationData (Section 3.10.3). In[1]:=
2.10 Nonlinear Symbolic Approximation 171 In[5]:= Plot3D[ivloadPSpice[VLOAD, II], {VLOAD, 0., 3.5}, {II, 0., 0.001}, AxesLabel −> {"VLOAD", "II", ""}, PlotLabel −> "IVLOAD (PSpice)"] IVLOAD (PSpice) 0.0003 0.0002 0.0001 0 1 VLOAD 2 3 0 0.001 0.0008 0.0006 0.0004 II 0.0002 Out[5]= SurfaceGraphics Equation Setup In the next step the equation system has to be set up. For this we import the PSpice .cir-file and convert it into an Analog Insydes Circuit object using the command ReadNetlist (Section 3.10.1). In[6]:= netlist = ReadNetlist[ "AnalogInsydes/DemoFiles/Sqrt.cir", Simulator −> "PSpice"]; DisplayForm[netlist] Out[7]//DisplayForm= Circuit: Netlist Raw, 8 Entries: Q1, 3 C, 5 B, 0 E, Model ModelBJT, BJTNPN, Q1, Selector Selec Q2, 1 C, 3 B, 5 E, Model ModelBJT, BJTNPN, Q2, Selector Selec Q3, OUT C, 3 B, 4 E, Model ModelBJT, BJTNPN, Q3, Selector Sel Q4, 4 C, 4 B, 0 E, Model ModelBJT, BJTNPN, Q4, Selector Selec VLOAD, 1, OUT, Type VoltageSource, Value AC 0, DC Transient 3.

Since we are not interested in temperature effects, we instruct CircuitEquations (Section 3.5.1) to replace TEMP, TNOM, the elementary charge $q, and Boltzmann’s constant $k by their numerical values.
