Cadence PDK
What is a Chartered PDK?
Chartered Process Design Kits (PDK) contain all the Chartered-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.
Chartered PDKs contain the most accurate process data available for Chartered'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.
Chartered PDKs help customers streamline the design process, enabling the realization of high-performance products.
How are Chartered PDKs used?
Chartered 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 Chartered PDKs.)
What is in a Chartered PDK?
The PDK contains information specific to each design task and to specific design tools.
(Figure 2 - How Chartered 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 Chartered 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 Chartered PDK ensures
that designers can get started quickly and not worry about missing
design data.
Back-End Design and Accelerated Layout
Chartered 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 Chartered 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.
