Power integrity and electromagnetic interference analysis

CADSTAR Power Integrity Advance

CADSTAR Power IntegrityCADSTAR Power Integrity Advance provides fast and practical power integrity and electromagnetic interference analysis within the CADSTAR PCB design flow, offering EMI, AC and DC power analysis to help you determine the best decoupling and power distribution strategy for your layout.

Designs that utilize numerous complex high pin-count ICs such as FPGAs, DSPs and CPUs operate on multiple voltage rails, requiring careful planning of the power distribution system to minimize parasitic noise and fast switching currents that can negatively impact system performance and EMC behavior.

Power Integrity Advance provides full board EMC screening for both differential and common mode board level EMC, allowing the Layout Specialist to identify potential electromagnetic emission hotspots at an early stage and resolve them by revising component placement, routing, layer assignment and power distribution strategies.

DC Analysis creates an equivalent DC circuit of your PCB that includes model information to verify DC voltage drop and current flow, helping to identify design features such as plane splits or areas of high via density that may cause voltage drop at the target device.

AC Analysis verifies plane impedance characteristics to assist the design engineer in the planning and selection of the decoupling capacitor network, helping to optimize board real estate and determine the correct distribution of decoupling capacitor values.
