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.
 
 

Tanner 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.

682r Class Download

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.
