techniques utilise a separate model for each piece of interconnect and cascade these models together in a circuit simulation tool, which can be an error-prone process due to the 3D nature of the transition from the PCB to the connector.<\/p>\n<p>In addition, since the 3D transition can make or break signal integrity, at very high speeds designers also want to optimise the transition from the connector to the PCB or the socket to the PCB.<\/p>\n<p>The Sigrity 2018 release enables designers to take a holistic view of their system, extending design and analysis beyond the package and board to also include connectors and cables, all of which can impact optimisation of the high-speed interconnect.<\/p>\n<figure id=\"attachment_8606\" aria-describedby=\"caption-attachment-8606\"

id=\"caption-attachment-8606\" class=\"wp-caption-text\">Sigrity 2018 release 3D solver view of a Rigid-Flex design<\/figcaption><\/figure>\n<p>An integrated 3D design and 3D analysis environment allows PCB design teams to optimize the high-speed interconnect of PCBs and IC packages in the Sigrity tool and automatically implement the optimised PCB and IC package interconnect in Allegro PCB, Allegro Package Designer, or Allegro SiP Layout without the need to redraw.<\/p>\n<p>Until now, this has been an error-prone, manual effort requiring careful validation.<\/p>\n<p>By automating this process, the Sigrity 2018 release reduces risk, saves designers hours of re-drawing and re-editing and can save days of design cycle time by eliminating editing errors not found until the prototype reaches the lab.<\/p>\n<p>This reduces prototype iterations and potentially saves hundreds of thousands of dollars by avoiding re-spins and schedule delays.<\/p>\n<p>A new 3D Workbench utility available with the Sigrity 2018 release bridges the mechanical components and the electronic design of PCB and IC packages, allowing connectors, cables, sockets and the PCB breakout to be modeled as one with no double counting of any of the routing on the board.<\/p>\n<p>Interconnect models are divided at a point where the signals are more 2D in nature and predictable.<\/p>\n<p>By allowing 3D extraction to be performed only when needed and fast, accurate 2D hybrid-solver extraction to be performed on the remaining structures before all the interconnect models are stitched back together, full end-to-end channel analysis can be performed efficiently and accurately of signals crossing multiple boards.<\/p>\n<p>In addition, the Sigrity 2018 release offers Rigid-Flex support for field solvers such as the Sigrity PowerSI technology, enabling robust analysis of high-speed signals that pass from rigid PCB materials to flexible materials.<\/p>\n<p>Design teams developing Rigid-Flex designs can now use the same techniques previously used only on rigid PCB designs, creating continuity in analysis practices while PCB manufacturing and material processes continue to evolve.<\/p>\n<p>\u201cAt Lite-On, our Storage Business Group (SBG) focuses on solid state disk enterprise datacenter product design. It has become increasingly important to consider signal and power integrity on our extremely dense designs,\u201d said Andy Hsu, Lite-On SBG R&amp;D head. \u201cIn order to enhance 2D layout and 3D connector structure integration, Lite-On SBG has accelerated our design cycle by adopting the Cadence 3D solutions including Sigrity PowerSI 3DEM and the Sigrity 3D Workbench, which support seamless use of Cadence Allegro layout and Sigrity extraction tools.
