Lab 1 - ECE 421L
Pre-lab

For the second part of the prelab it was instructed to input a table into the webpage and add numbers to the rows and columns.

For this lab the main goal was to set up our individual cadence accounts in order to use the virtuoso command. This involved editing through the libraries as shown to us in our lab instructions as well as learning the commands on the consol. After getting the libraries set up we change directories to CMOSedu using the cd CMOSedu comand, and then using the command virtuoso & bring up our library manager as well as letting us to continue using the window with the &.

After launching the library manager a new library was created for lab one, which also had a cellview and schematic made for it as well. In the schematic view the task was to make a voltage divider with a 1V dc supply and two 10k ohm resistors. After selecting all the comonents they were connected with wire using the w command, then the wires were labeled with the l command.

After making the schematic the ADE window was opened and needed to have input a transient analysis for 1 second. Then The wires labled in and out were selected to be ploted for the transient analysis, showing that out is half the voltage of in.
