Q: What are the challenges that ANSYS will help me with?
A: There are five areas we offer analysis tools for:a. Signal Integrity
b. Power integrity
d. cooling strategies
e. mechanical integrity
Q: What is the approach of ANSYS on signal and power integrity?
A: ANSYS approach to signal integrity, power integrity and EMI problems of high-speed interconnects is to provide industry standard electromagnetic solvers (HFSS, Sentinel and SIwave) to accurately and efficiently perform electromagnetic extraction from within the ANSYS layout environment or directly from our ECAD partner’s layout tools.
Q: What is the learning curve for me with ANSYS tools?
A: As with all high-end analysis tools there is a learning curve. Depending on the engineer’s background it could formidable. The largest impediment to using electromagnetic extraction tools for electrical engineers has always been unfamiliarity of 3D modeling paradigms. Using technology such as HFSS for ECAD we provide access to our EM solvers directly from a layout environment. This technology has made EM extraction much easier for our users. In addition, ANSYS automatic adaptive meshing algorithms completely eliminate the need to build and refine a finite element mesh. Dealing with meshing issues has been another impediment to engineers using EM extraction tools early in the design process. Finally, ANSYS automatic output of parasitics to widely used circuit analysis tools such as ANSYS Designer and Synopsys HSPICE allows user to perform accurate circuit analysis including electromagnetic effects thus providing tremendous insight to signal and power integrity issues and EMI.
Q: When you’re not at work, what are your hobbies?
A: Coaching Little League baseball, golf and real estate investment
