Copyright 2001, Agrawa VLSI Test: Lecture 6 2 Simulation Defined Definition: Simulation refers to modeling of a design, its function and performance. A software simulator is a computer program; an emulator is a hardware simulator. Simulation is used for design verification: Validate assumptions Verify logic Verify performance (timing) Types of simulation: Logic or switch level Timing Circuit Fault (Lecture 7)

Copyright 2001, Agrawa VLSI Test: Lecture 6 4 Modeling for Simulation Modules, blocks or components described by Input/output (I/O) function Delays associated with I/O signals Examples: binary adder, Boolean gates, FET, resistors and capacitors Interconnects represent ideal signal carriers, or ideal electrical conductors Netlist: a format (or language) that describes a design as an interconnection of modules. Netlist may use hierarchy.
