Start up Cadence for the First Time

Part I. Set up environment variables and path:

1. Make sure you add the following lines to your .cshrc file:

set path= (/afs/ece/usr/mems/bin $path)
set path= ($path /usr/cds/ic/tools/bin /usr/cds/ic/tools/dfII/bin)
setenv CDSDIR /usr/cds/ic/

2. Create a top-level working directory where all your HP related designs will be stored, type

mkdir /afs/ece/usr/YourUserID/hp_cds

3. Change directory to this working directory you have just created by typing

Part II. Start Cadence:

1. To start Cadence, type

hp_cds &

* Note for advanced users: when you run hp_cds for the first time, it will create or overwrite the following files in the running directory:

.cdsinit  - Cadence startup file
.cdsenv  - contains environment settings
cds.lib - library directories. Contains library names and their corresponding path.
cdsinfo.tag - Cadence directory setting for current direcotry and its sub-directories

if you have editted one of these files, your customized lines will be lost.

2. The CIW (Cadence Interpreter Window) will popup



3. The Library Manager Window will also popup

Note there are three columns: Library, Cell, View.

* Note for advanced users: there are several built-in libraries in the Library Manager:

scn3mlc_submLib: default technology library; when you create a new library, attach your new library to mumpsLib to inherit tech info
NODAS_poly: this library contains mechanical instances like beam, plate, anchor...; used for constructing your MEMS device
NODAS_basic: this library contains force source, position source, angle source; used for simulation
analogLib: this library contains gnd, vcc...; used for designing electronic ciruits

Note: scn3mlc_submLib is solely for technology information, and does not contain any element or design cells

Part III. Create a new library:

1. In Library Manager window, click File => New => Library



This is the New Library window.

2. In New Library window, fill in the name of your new library (in this example, the new library name is test). Then click Ok at the bottom of the window. Cadence will then ask for the technology info associated with this design library.



Make sure "Attach to an existing techfile" is selected. Click Ok

3. A new window opens up asking you to specify the technology file.

Congratulations! Now you have initialized Cadence and created a new library with the MUMPS technology file. Your next step is to learn about schematic editing. Then you may also want to try out Tutorial 1 or Tutorial 2 before you start to create you own design!
