Introduction to SPICE (Version 16. 2) Prof. Shahrokh Ahmadi ECE 002

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 = Resistor VDC/Source = DC Voltage Source VSIN/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 … Press this one to start… Then, enter a name for your simulation…

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 D 1 N 4002 diode the cutoff voltage is around ~ 0. 6 Volts
