What they need


该职位来源于猎聘 岗位职责: - 配合封装/PCB设计,完成stackup以及阻抗要求评估; - 根据IP要求,分解高速信号/电源在封装+PCB无源链路设计指标,并且按照指标约束设计;

  • 85P阶段性完成高速IP信号前期layout方案,以及早期风险评估以及风险释放方案;
  • 95P阶段性,基于PI链路仿真需求,要求验证提供相应case,产生RTL功耗波形(早期缺少silicon寄生参数); 提前设别 关键数字电源域PI风险识别,提出优化电流行为缓解PI风险;完成封装/PCB上电容选型以及PDN优化;
  • 100P阶段完成封装/PCB设计+ PISI仿真3轮迭代优化;如果有风险无法释放,需要列出post-silicon测试验证计划,以及对应风险释放方案;
  • AI芯片PISI新技术保持追踪,提前预研落地项目,解决高速SERDES信号问题以及multi-core的电源di/dt问题,低电压大电流的供电问题; 任职要求: - 硕士研究及以上学历,电子相关专业或者计算机专业;
  • 8年及以上的PISI工作经验,具有PCIE5/RDMA/UCIE 等高速或者multi-core PI经验者优先; - 熟悉主流仿真工具 – Cadence/Ansys,时域以及频域仿真; - 熟悉高速信号PCIE5/UCIE/LPDDR4/4x etc等高速总线接口,具备对应的仿真和测试能力; - 具有CoWoS-S/ 3D芯片silicon 抽参数以及PI仿真经验者优先; - 具备技术探索能力,交付逻辑缜密,能够协同封装+PCB优化落地设计指标;
