Chaper 15 Steps of IC design design in C/C++ model –> simulators, func good design in RTL –> simulating, and compare with the C/C++ reference model Synthesis: Translate RTL to gate-level netlist. Place and Route: netlist as input, generates polygons that will become wires and transistors on the chip.

Chapter 20 Intro 1994, Intel spent $500 million to recall the Pentium CPU due to a functional bug that produced erroneous floating-point division results that were off by as much as 61/{1,000,000} [112]; Simulation-based logic verification is becoming less and less effective due to the growing complexity of the systems; Large systems are often decomposed into blocks each of these blocks is simulated separately in its own environment; full-chip/system simulation is carried out after block-level simulation is stable; A dramatic increase in the effort invested in simulation-based verification a complete simulation environment, including tests, checkers, coverage monitors, and environment models, is developed and maintained for each block; Half of the total design efforts is devoted to verification; The number of bugs is growing exponentially, and hundreds of billions of simulation cycles are consumed; Only a negligible percentage of all possible executions of the design is actually being tested.

The design of these ICs would not be humanly possible without software (SW) assistance at every stage of the process. The tools and methodologies used for this task are collectively called
