What is SPICE?
• SPICE stands for Simulation Program with Integrated Circuit Emphasis
• This software is widely used for analog and digital circuit design and also for educational purposes
To Start the Program…Start > Cadence SPB 16.2 > Design Entry CIS
Open a New Project
Select a Name for your Project
The Window Looks Like This
Place components using this icon
Component List
Component Library
In the case that you do not see the library list, please load the library list from here
R/Analog = ResistorVDC/Source = DC Voltage SourceVSIN/Source = AC Voltage Source
For Wiring use this icon
Wiring
The Red Dot means a Node where the wiring is correct!
Setting up the Voltage Source
By Clicking on the component value you can modify the value! (if you click on the component itself, you will be able to change more properties).
Placing the Probes
Voltage Probe Current Probe
Placing the Probes
Do not forget to put the ground in your circuit!
Start Simulating …
Then, enter a name for your simulation…
Press this one to start…
Time duration of the simulation
Now, you are good to go! Press the green “play” button to start the simulation!
If you want to rerun the simulation and you want to change the simulation properties, you can use this icon to bring up the menu!
If there is something wrong the window appears like this:
Results of the simulation
Use the same procedure to simulate a Diode!
For D1N4002 diode the cutoff voltage is around ~ 0.6 Volts
