ECE 581: Analog IC Design (Fall-2021)

Starting Cadence:

You can start the Cadence software with the following commands from the EWS Linux machines (you must be in your home directory to start):

			$ cd ~
$ module load ece581
$ cd ece581.work
$ virtuoso &

			

When you start Cadence, you may see warnings about “old versions” or “license not available”. Hit “yes” or “always” and ignore these.
Temporary Note: When you start ADE, go to Setup -> Environment, and make sure Run with 64 bit binary is checked. The simulator will not work otherwise.

c : Copy part
w : draw Wire
l : Label wire
q : Query properties
u : Undo (shift+u is redo)
r : Rotate (shift+r flips over y-axis)
t : direct Text edit
