In IC package design, it is becoming increasingly necessary to change a cline's width in a given region, whether for signal integrity reasons or to allow all necessary traces to pass through a particularly dense region. Power has Noise, voltage drop along traces, current density variation, and other problems occur. [PCB_FORUM] Re: Beginners Quiz for Signal Integrity for PCB Designers. I like the discussion of how twisted pair wire helps prevent radiation. Our APD AE expert, and in the SPB16.3 APD tool, there is an Edit> Cline Change Width command. Solution 2D Full Wave field solver (EMS2D) provides the full -frequency range analysis from DC, through the middle frequency range which covers the skin effect, to the THz range of the electromagnetic interactions which address resonances, radiations and EM signal integrity issues. High density interconnect on PCB and packaging designs with signal switch rates over 5 Gpbs require model characterizations that can support frequency ranges from DC up to THz. At these high transmission rates, signal integrity issues become increasingly restrictive on PCB trace and cable lengths, and on design implementation and features. However, this feature is not available in the Allegro PCB Editor tool. John Isaac The HyperLynx PI tool was created for designers to evaluate and mesh these power requirements, reducing the need for decoupling capacitators, shortening design times and eliminating respins, and improving signal integrity. This week, Mentor Graphics released HyperLynx PI, a design software program aimed at improving power integrity on the PCB.
