We introduce DRAGON, a suite of hardware simulation and optimization tools that enable hardware designers to simulate hardware designs, and to optimize hardware designs to efficiently execute certain workloads. The DRAGON toolchain provides the following tools: Hardware Model Generator (DGen), Hardware Simulator (DSim) and Hardware Optimizer (DOpt). Our work uses a simulation based method of running algorithms (represented as data-flow graphs) and architectures/technology (represented in a description language) to create the hardware model and then maps the algorithms on the hardware. We are able to generate architectures and circuits that are 5x better than previously published works [6, 7] and provide technology targets for improving to 100x and 1000x better computing systems. In conclusion, a new open-source, fast and explainable toolchain for end-to-end exploration and optimization of technologies and architectures is created.

DRAGON是一种开源的硬件仿真和优化工具链，提供了硬件模型生成器（DGen）、硬件仿真器（DSim）和硬件优化器（DOpt）。通过梯度下降的方法，DRAGON框架可以优化硬件模型，提供性能优化的架构和技术改进方向，是一种适用于AI和非AI工作负载的快速硬件仿真和优化工具。
