中文技术专区: 针对GPGPU设计，Cadence RTL到Signoff流程解密

FormerMember

近年来，随着GPU在通用计算领域的高速发展，逐渐将应用范围扩展到图形之外，例如人工智能、深度学习和自动驾驶。这些领域的特点要求GPU在并行处理海量数据的同时提供更高的访存速度和浮点运算能力。在这种计算密集度越来越高的情况下，我们也面临越来越严峻的挑战，比如在后端摆放和绕线阶段的拥塞问题，如何比较精确地在较早阶段考虑物理信息，预测布局变得尤其重要；在并行同步的信号会增多，大量的矩阵运算引入的情况下，Glitch Power占比会显著提高，如何在较前阶段去分析和避免glitch 功耗是我们避不开的难题；同时由于GPU重运算和流水线的设计加上众多旁路分支结构， OCV影响会更加显著，如何评估和解决时钟上OCV是解决时序收敛的关键因素。针对以上GPGPU面临的挑战和痛点，Cadence提供了一整套从RTL到signoff的全流程解决方案。
