Lab 1 - EE 421L
This lab will teach me how to use Cadence to build a schematic and perform transient analysis on the circuit. I will be building a simple DC circuit following the instructions in Tutorial 1 up to the 25th image.
The first step is to create a new library in Cadence using the library manager. We will name the library Tutorial_1. We will attach the AMI 0.60u library.
Now if I go look at my cds.lib file in the MobaXterm text editor I will see that my Tutorial_1 library is defined at the bottom of the list.
I can now create a cell in my Tutorial_1 library by selecting the library and using the drop down menu File>New>Cell View. I will name this cell R_div and make it a schematic type.
Now I can open up the schematic to a blank grid. I can start adding components by pressing the "i" key on my keyboard. This will open upthe add instance and the component browser windows. In the component browser I will select NCSU_Analog_Parts > R_L_C > res in order to place resistors and I can edit the value of my resistors in the add instance window. We will use 10k Ohm resistors.
A quick way to edit components is to use the key "q" to open up the properties window of the selected component.
Now that I can find my components I will build my circuit. I can connect components together using the key "w" to place a wire. I can name a wire by pressing the "L" key. We will use two 10k Ohm resistors and a 1V DC voltage source.
In order to simulate this circuit I will go to the menu Launch > ADE L. ADE stands for Analog Design Environment.
Now I will go to Analyses > Choose. This will open up a window to choose what type of analysis Cadence will perform. I will choose transient analysis with a stop time of 1 second.
I can choose which outputs will be plotted by selecting Outputs > To Be Plotted > Select On Schematic. I will chose Vin and Vout to be plotted.
Our ADE L window will tell me which time of analysis it will perform as well as which output will be plotted. I will also save this information so that I can easily return to this in the future. I will do this by selecting the menu Session > Save State and then select Cellview.
In order to simulate the circuit I will press the green play button on the side of the ADE L window. A window showing the Vin and Vout plots will pop up as well as a netlist.
I will regularly backup my labs by uploading them to my OneDrive.
I will also keep a copy of my lab folders on my desktop and on an external storage device.
