升级版的互连建模技术致力于解决PCB和IC封装设计中出现的问题。随着信号速度攀升至32Gbps乃至更快，将PCB和连接器进行整体建模势在必行。全新的 Cadence®Sigrity™3D Workbench技术，包括 Sigrity PowerSI 3D EM Extraction Option (3DEM), 可在用户导入机械结构——如电缆和连接器后，使之与PCB合并，从而对电路板到连接器的关键3D结构进行统一的建模和优化。同时，PCB的更新内容可以被自动反馈到PCB layout 工具中。
3D Workbench
业界首创的、从单一layout数据库中实现完全提取刚柔结合PCB的技术，可提供刚性和网状地面柔性电缆区域的精确互连建模。区域信息可自动从 Cadence Allegro® 技术的17.2版本中导入。
对于含有数千个bump/ball的IC封装设计，建模速度可提高3倍，内存消耗降低75％。
升级后的电源完整性（PI）技术可满足PCB从前端到后端设计流程的最新检查要求和最新可用性需求。添加了许多增强功能，包括树形结构（层次视图）、快速搜索和筛选、tree的对比报告及工具提示。
升级后的DC分析技术增强了与Allegro平台的技术集成、支持HTML框图功能以及自动在焊盘添加节点的功能。
AC分析技术增强了检查功能，可查看加权电流并检查等电位。新的批处理模式“project”允许将这两个新工作流程以及其它的工作流程设置为一组，从而进行批处理检查。
升级后的信号完整性（SI）技术可加快验证存储器接口、串行链路以及PCB上过量的其它信号（这些信号可能导致设计故障）所需的时间。升级版引入了工作流程和视窗功能，可用于快速执行电气规则检查，以查找阻抗变化和过度耦合。这些检查不需要任何模型，可由信号完整性技术专家或领域新手轻松完成。
Sigrity 3D Workbench技术可令用户在导入机械结构后使之与PCB合并，从而使从电路板到连接器的关键3D结构获得统一的建模和优化。
