The nature of physical layout verification software depends onĬlarification: The nature of physical layout verification design rule checking software depends on whether the design rules are absolute or lambda-based or on whether or not the layout is on a fixed or virtual grid.ġ0. All possible errors in mask layout can be eliminated after mask making proceeds.Ĭlarification: The cost in time and the facilities in mask-making is such that all the possible errors must be eliminated before mask making proceeds.ĩ. It captures the design intent and not directly the physical layout.Ĩ.
Which verification capture’s design intent and not physical layout?Ĭlarification: Circuit description language where the primitives are circuit elements such as transistors, wires and nodes. This is used to check out the design.Ĭlarification: Selection and placement geometric shapes are done using some form of cursor and it may also allow selection of menu items.Ĭlarification: Positioning of cursor may be affected from keyboard and cursor position is controlled from a bitpad digitizer or a mouse.Ĭlarification: CIF is an example of mask level layout language, which are well suited to physical layout description but not for capturing the design intent.ħ. It will be required to check out the design before turning out the design in silicon.Ĭlarification: Simulators are available for switch level logic and timing simulation. Physical verification tools in design process includeĬlarification: Physical verification tools in design process includes design rule checking, circuit extractors, ratio rule and other static checks.Ĭlarification: Behavioral tools contain simulation at various levels.
