ADMS - Basics
http//sourceforge.net/projects/mot-adms/
Project adms Summary
ADMS is a code generator that converts electrical
compact device models specified in high-level
description language into ready-to-compile c code
for the API of spice simulators. 120 downloads
in two weeks (start september 03)

ADMS how to get xml interfaces

• xml interfaces available for SPECTRE-CADENCE and
  ADS-AGILENT
• CADENCE
• ask CADENCE support sign NDA
• ask for DPI kit (spectre interface) xml files
• AGILENT
• ask AGILENT support
• the xml files target the public interface of ADS
  (no need to download it)

Zspice I
http//sourceforge.net/projects/mot-zspice/
Project zspice Summary
zspice is a simple reconfigurable spice
simulator. Its device library is automatically
generated using adms, a software tool available
on SourceForge.net. More can be found at

Conclusion

• Two open-source tools have been presented
• Both tools are available on SourceForge.net
• Feel free to download the tools/send your
  feedbacks
• The developement of both projects is very active
• Visit frequently the SourceForge.net web sites
• EKV team plan to release EKV 3.0 using ZSPICE in
  October
