Gate-Level Simulation

Concept

Gate-level simulation is described in the provided evidence as a cycle-accurate but comparatively slow simulation approach in processor, FPGA, and EDA design flows. It is useful after a sufficiently complete hardware design exists, but evidence contrasts it with instruction set simulators for early software testing and with behavioral simulation/direct measurement approaches for faster FPGA power-monitor development.

Overview

Gate-level simulation is a hardware-design simulation approach referenced in processor and system design flows as providing cycle-accurate results.[1] In the processor-simulation evidence, it is contrasted with more abstract instruction set simulators (ISS), which are based on the instruction set architecture (ISA), commonly implemented in high-level languages such as C++, and used for pre-silicon software development before the target processor is manufactured or even before the design is finished.[2]
