CHAPTER 8 GERERAL OF IC DESIGN FLOW

The integrated circuit design process begins with which step?

• Physical design
• System specification
• Functional design
• Physical verification

The three-dimensional (3D) model in integrated circuit design includes which axes?

• Behavior, structure, physical
• Hierarchy, version, display
• Design, verification, manufacturing
• Logic, physical, functional

The Gajski-Kuhn Y-chart is used to

• Optimize circuit performance
• Determine manufacturing costs
• Describe design aspects at different levels of abstraction
• Manage design versions

In semi-custom design, which design type uses pre-manufactured components?

• Full-custom design
• Standard cell-based design
• Macro cell-based design
• Gate array-based design

The Design Rule Check (DRC) tool is used to

• Create a layout from a netlist
• Verify geometric rules for the mask layout
• Validate circuit functionality
• Optimize logic

The fundamental difference between analog and digital integrated circuit design is

• Digital design requires higher precision
• Analog design uses logic gates
• Analog design simplifies most of the process
• Analog design does not require physical verification

In the physical design process, which step is performed after placement?

• Logic synthesis
• DRC verification
• Signal routing
• System specification

Top-down design is a method that

• Starts from the transistor level and progresses to the system level
• Starts from system specification and progresses to more detailed design levels
• Manually designs each circuit part
• Uses pre-existing modules to create a larger system

One of the advantages of standard cell-based design is

• Maximum freedom in placing circuit blocks
• Fully automated layout process
• Optimal electrical performance
• Shorter design time compared to FPGA

In analog integrated circuit design, “thinking before designing” means

• Using CAD tools from the start
• Analyzing performance and performing manual calculations before starting design with CAD tools
• Optimizing the layout before defining system specifications
• Designing small blocks first and then combining them into a larger system
