Analog
Cell Library
This is the standard cell library being
developed for the VLSI lab. Many of the cells are also for use in the 493r
class lab. Cells datasheets are posted in PDF format along with a ZIP file
containing CIF, GDSII, and L-EDIT[tdb] files. For some cells, there are
also corresponding MicroSim PSpice files included in the ZIP file.
note: for the 493r class, all the
necessary PSpice libraries are available on CAEDM PC's along with the VLSI
Lab computers. A lot of the circuits can be built on the PSpice evaluation
version installed on CAEDM PC's even though the circuits are too large
for the evaluation version to simulate. Once the limits have been reached
on the evaluation version, students may come into the VLSI lab to run simulations
of their DAC.
Digital
Cell Library
This is a link to the Scalable
CMOS Library provided with L-Edit. In order to use this cell
library you will need to have L-Edit installed on your computer.
Padframes
For Mosis Projects
Analog padframes are available in the
*.TDB file format for ORBIT20 and AMI12 processes. A detailed datasheet
for the AMI12 process is now posted in this section. The new datasheet
provides plots and explanations of each padframe subcell used in making
standard padframes. This should be useful for those that want to custom
build a padframe with buffered digital I/O and also take advantage of analog
ports.

Research- L-Edit
The Windows95 ver 6.02 of L-Edit is posted
here for students to download. Keys are available for checkout in room
416 CB.
PSpice
Tutorial
This is a tutorial to help students and
research assistants learn MicroSim's PSpice for the PC. This tutorial starts
out at an elementary level, but also covers advanced features like PARAM
which allow quick and powerfull analysis of circuits.
PSpice
[dos] version 5
This is a demo version of PSpice on the
DOS operating system. It has been posted here so students can download
and install on their home computers and practice coding circuit. Even though
the DOS version of this program is no longer being sold, it is still beneficial
for students to become familliar with netlist files since these file types
are used by many simulation tools.

Milling
Machine Documentation
Contatins instructions for exporting gerber
files from MSim board layout program, importing the gerber files into the
LPKF CircuitCam, and instructions on operating the milling machine.
note: A good site to check out for help with GERBER files is artwork.com. They have a good application note on gerber files explaining the history and structure of the format. Knowing this will help you understand the file conversion from one CAD package to another.
