随着Q3D v8的发布,Q2D终于摆脱传统的Maxwell控制面板,集成到Q3D的桌面系统中,易用性得到大大提高。 随着互连速度越来越高,Q3D正在鸡肋化,在SI上的应用正逐渐让位于HFSS,Q3D的尴尬在于准静态的电磁场算法,限制了它不适用于高频场合。 用得多的是Q2D,可视化界面,比Hspice里面的文字描述建模来得方便,而且可以适用于任何剖面形状,多导体数也没有限制,Q2D是业界提取均匀传输线模型的事实标准。 Release offers new capability and streamlined user interface for signal integrity analysis
PITTSBURGH - February 21, 2008 - Ansoft Corporation (NASDAQ: ANST) announces Q3D Extractor?v8, the latest version of the company's 3D parasitic extraction software. Q3D Extractor efficiently performs both the 2D and 3D electromagnetic field simulation required to extract RLCG parameters from an interconnect structure and automatically generates an equivalent SPICE circuit model for use in Nexxim? the company's high-capacity circuit simulator, or other Berkeley SPICE-compatible tools. These models provide an EM-based design synthesis solution for on-chip passives and speed the design and optimization of high-performance structures in order to achieve first-pass timing closure. Q3D Extractor v8 includes a new capacitance solver that is capable of extracting the capacitance and conductance with lossy dielectrics. This new solver is optimized to exploit available computer memory and perform multiple frequency evaluations and allows users to model infinite ground planes. Additionally, the Ansoft next-generation desktop architecture has been added to the 2D extractor tool. This intuitive, easy-to-use interface offers many new usability enhancements, including the ability to perform discrete and interpolating frequency sweeps, simplified problem setup, fully scriptable report editor, enhanced post-processing and advanced product coupling capability with Nexxim and Simplorer? Ansoft's multi-domain system simulation software. Engineers use Q3D Extractor to understand the performance of high-speed electronic designs and perform signal integrity analysis, including crosstalk, ground bounce, interconnect delays and ringing analyses. Additionally, Q3D Extractor is combined with Simplorer in high-power applications where users extract parasitics from cables and bus bars to predict EMI in electric drive systems. Highlights of Q3D Extractor v8 include: New Capacitance solver in Q3D Extractor that solves for C and G in lossy dielectrics Next-generation desktop architecture for 2D Extractor Infinite ground plane capability Multiprocessing and Distributed Analysis options Frequency-dependent dielectric loss model (Djordjevic-Sarkar) GDSII export Pricing and Availability: Q3D Extractor v8 is available for Microsoft Windows?XP Professional, Server 2003 Standard Edition, XP Professional x64 Edition, Server 2003 Standard x64 Edition, Red Hat Enterprise Linux v3 (32 and 64 bit) and v4 (32 and 64 bit), SuSE Linux Enterprise Server v9 (32 and 64 bit) and Solaris versions 8, 9 and 10.
