Cadence PDK's

What is a GLOBALFOUNDRIES PDK?

GLOBALFOUNDRIES Process Design Kits (PDK) contain all the GLOBALFOUNDRIES-provided process models and process data in the appropriate Cadence® technology file formats to enable fast and silicon-accurate IC design in the Cadence® Virtuoso® custom design platform.

GLOBALFOUNDRIES PDKs contain the most accurate process data available for GLOBALFOUNDRIES's comprehensive semiconductor manufacturing technologies. Automated methods and a well-established quality program assure highest level standards are met before each PDK is made available to customers.

GLOBALFOUNDRIES PDKs help customers streamline the design process, enabling the realization of high-performance products.

How are GLOBALFOUNDRIES PDKs used?

GLOBALFOUNDRIES PDKs drive silicon accuracy across the Virtuoso platform's various design tasks. These tasks, including Multi-mode Simulation, Accelerated Layout and Silicon Analysis, derive their bottom-up, silicon accuracy directly from the PDK and form the basis of the bottom-up flow in the advanced custom design methodology's "Meet in the Middle" approach.

(Figure 1 - The Cadence® Virtuoso® custom design platform derives its silicon accuracy directly from GLOBALFOUNDRIES PDKs.)

What is in a GLOBALFOUNDRIES PDK?

The PDK contains information specific to each design task and to specific design tools.

(Figure 2 - How GLOBALFOUNDRIES PDK data maps to the Cadence Virtuoso platform's design tasks.)

Advanced Device Modeling and Front-End Design

In order to provide the fastest, most silicon-accurate design capability, the latest device and interconnect models must be made available to the designer. This data is derived using the Virtuoso Advanced Device Modeling tools. These tools perform extraction, optimization and verification of device and interconnect models. The front-end design section of a GLOBALFOUNDRIES PDK also contains information that allows designers to drive the Virtuoso Specification-driven Environment and Multi-mode Simulation. From schematic symbols (with CDFs and callbacks) to device simulation models, the GLOBALFOUNDRIES PDK ensures that designers can get started quickly and not worry about missing design data.

Back-End Design and Accelerated Layout

GLOBALFOUNDRIES PDKs contain the data necessary to drive back-end design tasks using the Virtuoso Accelerated Layout capabilities. The PDKs contain PCells and layouts for a variety of components, and this data is matched to both the front-end design data as well as Virtuoso platform's physical verification design tasks.

Physical Verification and Silicon Analysis

The PDK physical verification section includes Assura DRC/LVS and leading-edge 3D device-level parasitic extraction from Assura RCX. Rule decks for DRC and LVS are developed collaboratively with GLOBALFOUNDRIES and are fully qualified for analog and mixed-signal/RF design flow with the widely used Virtuoso platform, providing a seamless front-to-back design solution customers can rely on. The heart of the physical verification section is Assura RCX, which is a comprehensive parasitic RLCK extraction solution for analog and mixed-signal/RF design. Assura RCX provides the foundation for silicon-accurate simulation and analysis, allowing designers to optimize layouts interactively to increase chip performance and silicon yield.
