ModelLib: A Web-Based Platform for Collecting Behavioural Models and Supporting the Design of AMS Systems

Abstract-This paper presents a modelling methodology for the top-down/bottom-up design of RF systems based on systematic use of VHDL-AMS models. The model interfaces are parameterizable and pin-accurate. The designer can choose to parameterize the models using performance specifications or device parameters back-annotated from the transistor-level implementation. The abstraction level used for the description of the respective analog/digital component behavior has been chosen to a good trade-off between accuracy, fidelity, and simulation performance. These properties make the models suitable for different design tasks such as architectural exploration or overall system validation. This is demonstrated on a model of a binary FSK transmitter parameterized to meet very different target specifications. The achieved flexibility and systematic model documentation facilitate their reuse in other design projects.

“…It shall allow to gather behavioral models, to validate collected models through collaborative review and development, to organize meta-model information, and to allow queries supporting the top-down and bottom-up design approaches. [2] ModelLib is realized as an open-source framework, but will implement appropriate IP protection mechanism for the stored documentation and models. This way, sensitive models may be kept from unauthorized use, while still keeping access to the related meta information.…”

Abstract-Systems-on-Chips (SoCs) integrate more and more heterogeneous components: analog/RF/digital circuits, sensors, actuators, software. For the design of these systems very different description formalisms, or Models of Computation (MoCs), and tools are used for the different subblocks and design stages, which often create interoperability problems. Additionally the verification of a complete SoC is difficult due to huge performance problems. The goal of this Ph.D. work is to develop an efficient modeling and simulation platform that supports the design of mixed-signal SoCs using component models written in different design languages and using different MoCs. One component of this work is the development of a web-based platform for collecting behavioral models and supporting the design of Analog and Mixed-Signal (AMS) SoCs. Its current state and an outlook on its further development is the focus of this paper. I. IThe design of SoCs has currently to address a number of significant issues, namely: increasing complexity (computing and communication capabilities), significant heterogeneity (analog, RF and digital hardware, embedded software, sensors, actuators), increasing environmental awareness (energy saving, environmental monitoring and interaction), increasing sensitivity to silicon technologies (deep sub-micron technological processes), and increasing reuse of subsystems (ever shrinking time to market). One difficulty in solving these issues while designing a mixed-signal SoC is the usage of a diversity of specialized EDA tools, design languages and design formats that are usually efficiently supporting only one aspect, i.e., RF, analog, or digital, of the complete mixed-signal system. Furthermore, the design's heterogeneity requires a diversity of description formalisms, also called Models of Computation (MoCs), analysis and simulation methods. It is still difficult to handle all the different design aspects simultaneously. Designers are forced to bridge the gaps between tools and methodologies using manual conversion of models, proprietary tool couplings, and tool integrations. This makes the design process overly complicated, error-prone and time consuming. Another very important issue is the capability to perform efficient overall system verification in the early phases of the design process. System verification is based on the development of virtual prototypes [1] of the complete heterogeneous system. Its main goals are to support architecture exploration, performance estimations, validation of reused parts, verification of the interfaces between MEMS, RF, analog, and digital parts, This work has been funded by the Hasler Stiftung under project № 2161. the interoperability with other systems, and the assessment of the impacts of the future working environment and the used manufacturing technologies. Modeling tasks are therefore at the heart of the V-shaped SoC design process (Fig. 1). The management of the created models of a device, component, or the whole system on different abstraction...
