OSIRIS Migration Technology

IN2FAB's production-proven OSIRIS technology provides a rapid path to move existing analog and mixed-signal circuits between foundries, processes and geometry size.  Based on platform tools from Cadence design systems, OSIRIS is fully integrated with common design environments and process design kits (PDKs) from all of the world's leading foundries and library vendors.   Using intuitive analysis tools, OSIRIS migrates schematic, layout and other design based information to meet the target foundry's specification without the need for special rules files, design constraints or extended EDA support.

  • Rapid set-up of rules and devices
  • Simple mapping of layers from source to target process
  • Interactive mapping of parameterized cells and vias
  • Layout preserved in the Cadence Virtuoso layout environment
  • Schematic data translated in the Cadence Composer environment
  • Fully compatible with internal and foundry design kits

OSIRIS Methodology

OSIRIS tools work within the Cadence framework giving complete database and design kit compatibility

OSIRIS Schematic Migration

IN2FAB's schematic migration system is a comprehensive tool dedicated to moving complete design hierarchies between processes and foundries.  Based on the Composer™ schematic editing tools from Cadence Design Systems, OSIRIS provides a smooth path from source to target PDK, including full physical postition and rewing along with parameter maping and translation.

The conversion process is engineered to be "designer friendly", reducing the need for specialist CAD support and handing control of the migration process to circuit engineers.  Physical changes, wiring updates, parameter conversion and more are automatically handled by the tools themselves, without detailed system or PDK knowledge from the user.


  • Full hierarchy and view support
  • Intuitive GUI driven flow
  • Automatic adjustment for component differences
  • Advanced parameter mapping
  • Automatic rewiring for pin changes
  • Add or remove wires for pin differences
  • Short detection and rewiring
  • Dedicated tool for comparison checks
  • Optional flow extensions using Skill™ software

OSIRIS schematic migration software is available for Cadence 6.1.x formats


Schematic Migration

Layout Migration

OSIRIS Layout Migration

The OSIRIS layout migration tools are designed to move layout data to new processes in the fastest way possible, removing the need for complex rule set up and extended CAD support.

Using the structure of the existing design in combination with the information contained in the target PDK, OSIRIS replaces old Pcell and via instances with those from the new foundry. Further processing steps then adjust the layout to match the new components while preserving the original topology and hierarchy.

Working interactively within the Virtuoso™ layout design tools, the tools give the user the flexibility to modify the design at any stage of the migration process and make structural changes to their layout while OSIRIS takes care of data processing and shape based violations.


  • GDSII or Cadence database input
  • Preservation of topology and routing
  • Full hierarchy and view support
  • Intuitive GUI driven flow
  • Advanced parameter mapping
  • Interactive design processing
  • Connection adjustments for Pcell differences
  • Interactive shape based adjustment
  • Preservation of advanced design information

OSIRIS layout migration software is available for Cadence 6.1.x formats


Viewdraw Schematic Translation

IN2FAB's Viewdraw and Viewlogic translation module is the industry's only direct method of transferring files from Viewdraw tools in to Cadence's Virtuoso schematic editor.  Viewdraw files are read and translated in a single process without needing to use EDIF or other interchange formats.

Once translated, schematic files can be edited and used in the same way as any other schematics. Additionaly, combining the translated data with the OSIRIS schematic migration software means designs can be updated to use symbols and models from the latest foundry design kits, giving full netlisting and simulation capability in the Cadence envirnoment.

  • Direct file translation of symbols and schematics
  • Primitive and pin library translation
  • Spice netlist views converted to schematics
  • Support for multi-sheet symbol views
  • Support for scaled symbols
  • Translation of single and multi file libraries
  • Optional scaling during translation
  • Full bus and multiple net support
  • Automatic resolution of incompatible database objects

Viewdraw translation software is available for Cadence 5.1.x and 6.1.x formats
