Mentor Graphics HyperLynx PI PCB设计

Power integrity (PI) analysis is an essential part of modern electronic design. The ever-increasing number of voltages being used by ICs, in addition to dramatic increases in power consumption, make proper power delivery an exceedingly difficult task. Compounding these issues are reduced layer counts, smaller noise margins, and increasing operating frequencies. With inadequate power delivery, designs exhibit signal integrity errors, which cause the logic on the board to fail.

Hardware engineers, PCB designers, and signal integrity specialists alike can use HyperLynx PI, getting simulation results without requiring weeks of software training. You can identify power distribution problems early in the design, even prior to layout. You can also identify problems with your design that would be difficult to identify in the lab, and investigate solutions in an easy-to-use “what-if” environment. Once the layout is complete, you can validate the results to ensure that appropriate guidelines were followed. This will ultimately help you reduce prototype spins and get to market faster, while creating more reliable products.
