This is the same example as the previous one but written for HSpice.

The inputs can be the same for both PSpice and HSpice. However, HSpice allows you to name nodes instead of numbering the nodes. To illustrate this we will call the input node "input" and output node "output".

We are interested in finding the following characteristics of the circuit given below:

1. Node voltages v12, v2 and current i4 when vin=10V
2. Thevenin equivalent voltage and resistance, seen at the output terminals v(3,0)
3. Sweep the input from 0 to 20V in steps of 2V and plot the voltages v12, v2, vo and the current i4.

Example of an HSpice: Thevenin Eq. ciruit and DC Sweep

VIN input 0 DC 10

F1 0 output VMEAS 0.5

VMEAS 4 0 DC 0

*VMEAS is a 0V source to measure i4

R1 input 2 1K

R2 2 output 10K

R3 input output 15K

R4 2 4 40K

R5 output 0 50K
