IBM PDK

Mixed Signal Design

Kit

CAE Tools

  Key Features:   IBM PDK V1.6   IBM Standard cell and IO pad libraries

  Physical Layout views available.   Separate substrate contacts

for mixed signal low noise applications.   Access to standard cells libraries is legally

covered by already established IBM CDAs

  New versions of CAE Tools   Open Access database support.

  Interoperability of Virtuoso and SOC-Encounter platforms.

  Compatible with the “Europractice” distributions.   Virtuoso IC 6.1.3, Analog front-end design   SOC Encounter 7.1 Mixed signal back-end design   IUS 8.1 support for simulations.   Calibre support for Sign-Off Physical Verification

  Support for LINUX Platform (qualified on RHEL4)   Two independent design kits:

  CMOS8RF-LM (6-2 BEOL)

  CMOS8RF-DM (3-2-3 BEOL)

Design Workflows

Digital Library

PDK   Analog & Mixed Signal (AMS) Workflows.

  Formalize the design work by employing standardized and validated Design Workflows.

  Formalize the design work across design teams in common projects.

  Provide a repository with reference design examples.

  Development work subcontracted to Cadence, VCAD design services.

  Close collaboration of CERN - VCAD - IBM   VCAD brought in their invaluable expertise on the CAE tools   IBM provided the physical IP blocks and important technical assistance   CERN assisted the development and validated the design kit functionality.

Design Kit Distribution

  The Design kit V1.6 is available to all collaborating institutes that have signed a CDA with IBM.

  No access fees required.

  Pay-per-use scheme.   Prototyping must be done exclusively through CERN.   A 7% fee will be applied on the prototyping costs.   This should cover part of the design kit maintenance costs in the long

term.

Objectives

  Workshop Targets:   Present the IBM CMOS8RF (130nm) Mixed Signal Kit.   Present Workflows for Analog, Digital and Mixed Signal designs.   Introduce the new Platform of Cadence CAE Tools.

  This is NOT:   A course on analog or digital designing.   An advanced course targeted to a specific Cadence Tool.
