I.Introduction



This Design Kit contains the technology library OPDK_TechLib. It supplies techfiles, display resources, design rules and scripts to permit layout design and rule checking in organic electronics design based on ion gel techniques.

This Design Kit is developed under the framework of NCSU 45nm FreePDK. Many thanks to all developers of NCSU open-source design kits for their effort.

The technology information is based on the ion gel technique developed by Department of CEMS, the University of Minnesota. This information may be used, modified and distributed under the permission of Dr. C. Daniel Frisbie of Department of CEMS, the University of Minnesota, and under the open-source Apache License (see the file APACHE-LICENSE-2.0.txt in the root install directory for the complete text).

This technology is intended to work with the ion gel technique models. The information of these models may be used, modified or distributed under the permission of the Department of CEMS, the University of Minnesota. Schematic creation and HSPICE simulation for these models is supported through Cadence Virtuoso and the Cadence Analog Design Environment (ADE), when using the OPDK_Devices library, also distributed with this kit.

This manual is intended as an introduction to the kit. For any questions, please contact zhang758@umn.edu

II. Setup Files



To use the kit, copy the following files from the cdssetup directory to the directory where you start Virtuoso:

cdsinit - Should be named .cdsinit
cds.lib - Cadence Library Manager library list
lib.defs - Open Access library list
.runset.calibre.drc - Calibre DRC runset file, with the rules path included.
.runset.calibre.lvs - Calibre LVS runset file, with the rules path included.

Sourcing the script setup.csh (in the cdssetup directory) will copy these files into the current directory if they do not exist and set the necessary environment variables to ensure that they are used by Calibre Interactive.

III. Design Rule Notes



The design-rules currently support 25 layers, including four layers as channel material and two metal layers (metal 1 and metal 2). See the "Layers" on "Design Rules" page on the OPDK Webpage for a complete list of layers. These design rules are not comprehensive, but represent our current state of understanding about how to design organic circuitry under ion gel technique for high yield. More detailed rules are still under development.

Design rule checking is currently supported with Calibre. The drc rules can be found in techfile/calibre/calibreDRC.rul. See "Tutorial" on the UMN OPDK Tutorials page for an introduction on running Calibre DRC from Virtuoso. There are currently no plans to support other DRC tools (e.g. Diva).

See the "Design Rules" pages on the OPDK Webpage for illustrations of all design rules. Please also see the file OPDK_Release_Notes.txt for notes on specific design rule changes in this release.

IV. LVS Notes



Layout vs. Schematic (LVS) Checks and is supported for all metal layers and devices (TFTs, resistors and capacitors) in the OPDK_Devices library. Parasitic Extraction (PEX) is currently not supported. This functionality is supported with Calibre. The rules can be found in the calibreLVS.rul file in the $OPDK_DIR/organic_basekit/techfile/calibre directory. See "Tutorial" on the OPDK Tutorials page for an introduction on running Calibre LVS from Virtuoso.
