1. 1. Electrothermal Simulation in a Concurrent Waveform Relaxation Based Circuit Simulator

   Författare :Magnus Wiklund; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circuit synthesis; Bond graphs; Nullor; Circuit theory; Analog simulation; Circuit simulation; Multiprocessor computer; CONCISE; Parallel computation; Waveform relaxation; Thermal models; Transistor models; Electro-thermal simulation; Electro-thermal modeling; Translinear circuits; Electronics; Elektronik; Electrical engineering; Elektroteknik;

   Sammanfattning : The main purpose of this work is to study methods to simulate electro-thermal effects in integrated circuits using CONCISE a waveform relaxation based circuit simulator. WR is a method that is suitable to run on a multi-computer with state of the art computing power. Especially CMOS VLSI circuits have been simulated successfully with WR. LÄS MER

3. 2. Analog Circuit Topology Development: Practice methods for technology and teaching based on comprehensible transistor models

   Författare :Roger Malmberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; episteme; analog design; circuit synthesis; field-effect transistor; teaching method; phronesis; techne; bipolar transistor; transistor model;

   Sammanfattning : To obtain adequate knowledge for design of robust analog circuits in industry, circuit engineers gain main knowledge from own practice experience, because theory taught by universities rarely states validity limits and result spreads. Therefore, when going from university to industry, the engineers find this theory nontrustworthy and relinquish it. LÄS MER

4. 3. All Around Logic Synthesis

   Författare :Maxim Teslenko; Hannu Tenhunen; Michel Berklaar; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; graph dominators; FPGA mapping; redundancy removal; RBN; Computer science; Datavetenskap;

   Sammanfattning : This dissertation is in the area of Computer-Aided Design (CAD) of digital Integrated Circuits (ICs). Today's digital ICs, such as microprocessors, memories, digital signal processors (DSPs), etc., range from a few thousands to billions of logic gates, flip-flops, and other components, packed in a few millimeters of area.
