Abstract: With the increasing demand for chip computing power in the fields of AI and high-performance computing, the chiplet solution is attracting more and more attention in the industry. However, the expansion of complexity and scale in multi-Die systems leads to issues such as high server resource consumption during simulation and extended verification delivery cycles. To solve these problems, this paper analyzes the traditional three-step method and socket verification method, and focuses on the Cadence distributed simulation solution. Based on an actual chiplet project, this paper breaks down system-level simulation tasks into multiple sub-Dies for parallel execution, and explores distributed simulation measures to improve efficiency from multiple aspects, such as server memory, cross-server communication delay, precise synchronization time adjustment, signal connection start time, and signal connection quantity. This achieves ultra-large-scale chiplet system-level RTL simulation and improves regression efficiency.

引言
隨著高性能計(jì)算、人工智能及自動(dòng)駕駛等帶寬密集型應(yīng)用的快速發(fā)展,傳統(tǒng)大的單芯片面臨良率風(fēng)險(xiǎn),推動(dòng)著系統(tǒng)架構(gòu)正從傳統(tǒng)單芯片向多芯片集成方向演進(jìn),但這也導(dǎo)致系統(tǒng)級(jí)驗(yàn)證難度顯著增加。現(xiàn)有驗(yàn)證方法在應(yīng)對Chiplet系統(tǒng)級(jí)仿真時(shí)存在運(yùn)行效率低下、驗(yàn)證交付周期長等問題。因此,本文探索了基于分布式仿真的驗(yàn)證方案,通過構(gòu)建并行化仿真任務(wù)調(diào)度機(jī)制和資源分配策略,實(shí)現(xiàn)多芯片協(xié)同驗(yàn)證的效率提升。
