What are the software tools that traditionally simulate and analyze the PDN noise challenges which WEMTECs technology addresses?
Software tools for power integrity analysis include SIwave from Ansoft, Power Si from Sigrity, and Power Grid from Apache. Other more general purpose electromagnetic analysis tools may also be used, such as 3D full-wave simulators from Ansoft and CST. • Q: Is the implementation of EBG structures into printed circuit boards something that can be done with standard PCB design and assembly processes, or would a new tool set need to be developed? A: Since WEMTEC EBG structures may be implemented as planar printed structures using conventional cores and metal layers, then standard layout tools such as those offered by Cadence or Mentor Graphics may be used for patch and via layout. Layout can be done for organic printed circuit boards, multilayer ceramic modules, or even silicon wafers. However, the design and validation of an EBG structure to satisfy certain frequency goals will require a more specialized tools set. An initial design may be created using effective medium models found in pr
