3. 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

4. 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

5. 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
