Design Methodology II EMT 251
Application Specific Integrated Circuits (ASICs) IC Standard IC ASSPs ASIC Programmable IC Semi Custom IC Custom IC FPGA Gate Array Linear Array Standard Cells Full Custom IC ASSPs : Application Specific Standard Products
ASIC Design Methodologies ASIC Design Methodology This approach is extremely slow, expensive It is only used to design very high performance systems Full-custom design This approach is reasonable fast, less expensive Most ASICs are currently designed using this method Standard-cell based design This approach is fast and less expensive ASIC performance are relatively slow Gate-array The design process is very fast and cost effective ASIC performance are slow FPGA based
ASIC-Benefit • Improve performance • Reduce power consumption • Reduce production costs • Mix Analog and Digital Designs • Design optimization through IC manufacturing process • Development Tools support HDL and Schematic design approach
ASIC-Drawbacks • Inflexible design • Deployed systems can not be upgraded • Mistakes in product development are costly • Updates requires a redesign • Complex and expensive development tools
