WebbSIwave employs a 2D Eigen solver to establish the natural resonant frequencies in the power-ground structure and the field distributions or Eigenmodes, that are associated with them. The natural resonances are the resonances that may occur in the power/ground structure if there is an electromagnetic source that excites them. WebbANSYS SIwave Power integrity, signal integrity and EMI SIwave is a dedicated tool for electrical analysis of full PCB and complex electronic packages. SIwave solves interrelated PI, SI, and EMI challenges to deliver predictive analysis for your design. It provides solutions in both the Time & Frequency domains.

Webb6 juni 2024 · DP is a method for solving problems by breaking them down into a collection of simpler subproblems, solving each of those subproblems just once, and storing their solutions. The next time the same subproblem occurs, instead of recomputing its solution, you simply look up the previously computed solution. WebbSIwave utilizes the Icepak solver plugin to simplify the thermal analysis setup and observe the heat map within the same SIwave interface (Fig. 4). Icepak can also be used through the Electronics desktop for use in designing heat sinks, fans, and integration with larger systems. Figure 4: Icepak Thermal Analysis.
