Implementation of prototype building blocks for a DAB standard Final report

DAB (Digital Audio Broadcasting) is a basically new development of a broadcasting system to be based on the standard elaborated within the Europroject EUREKA 147. With regard to a future wide introduction of DAB it is essential that DAB-receivers have to be made available as mass products at low unit costs. The DAB-technique applies highly sophisticated algorithms to be processed in real time. Therefore, the realization of such receivers is only feasible by means of highly integrated application specific monolitically integrated circuits (ASICs). Furthermore the problems to be solved are so extensive and of different kind that they can only be treated useful in an consortium project. Within the consortium project a set of test-ASICs has been developed, realized, and tryed which are the key components of the receiver (and partially also of the transmitter). Integrated bipolar circuits for the analog part of the receiver have been realized as prototypes which are characterized by high dynamic range, good noise properties, and low power consumption. The digital signal processing algorithms were processed by means of two highly integrated CMOS-circuits in combination with a signal processor. Based on these key components the realization of DAB-receivers having a volume of three litres and a power consumption of about 50 Watts was possible. Multimedia components will become more and more important in future, that is why a further reduction of volume and power consumption becomes esssential.

Analog Expert Design System (AEDS) Abschlussbericht

Design automation has reached a considerable level in the digital field at the beginning of the project, whereas for analog and mixed analog/digital design it lags far behind. Therefore it has been the main objective of the project 'Analog Expert Design System' to support an environment for the analog and mixed analog/digital IC- and system design, which assures optimized performance combined with short time to market. Tools for analysis of analog and mixed analog/digital circuits were improved by new methods. In the field of analog circuit synthesis tools were evaluated and improved on the basis of knowledge and experience of analog experts. For the layout synthesis of analog circuits a new tool has been developed. For the verification of these tools an example library was designed including functional macro-models, layout module generators as well as acquired, documented and coded knowledge for analog circuit design. Furthermore new tools were implemented into frameworks or design environments. The work performed improved analog and mixed analog/digital design considerably. On this basis further development work will be done to make analog design even more effective and to close the gap between the design of digital and analog or mixed analog/digital circuits.

Analog expert design system Final report (1995-1996)

The main objective of this JESSI project was the development of methods and tools for the analog and mixed analog/digital circuit design. During phase II of the project ('92-'94) major progress was achieved in the area of tools supporting and improving the different steps of the design flow. Based on these results the goals for phase III ('95-'96) were defined, aiming at even more optimized tools to be used in the design flow. TEMIC put the main emphasis on the following topics: In the area of Analog Simulation a design centring tool was evaluated in practical use and substantially enhanced. A prototype tool performing thermal-electrical simulation was developed together with ANACAD. For the development of macro models VHDL-A was tested and the visual programming environment ViCE was created. For the verification of the electrical behaviour of circuits the tool NWB was developed, which is based on netlists. As a requirement for Circuit Synthesis TEMIC performed a systematic analysis and documentation of selected circuit classes. Symbolic analysis techniques were evaluated for the investigation of circuits. For the implementation of knowledge as well as execution of circuit synthesis the tool ACSYN was further enhanced. It is also well suited to explore the property-space of a circuit. The developed Layout Synthesis tool ALSYN was used in production and further enhanced concerning interactivity. Concurrently placement and routing algorithms were improved. A major step in increasing efficiency for analog layout design was done by using these tools. The developed compaction tool CAMBIO-XT was especially applied to layouts being transferred to a new process, showing also big reduction in design time. For the extraction of substrate parasitics improvements were achieved concerning handling of higher frequencies.
