parallel link design -凯发k8网页登录

design parallel links such as ddr

the parallel link designer app provides a dedicated system-level design and analysis environment for parallel links. capture your parallel link designs graphically and experiment with different physical layouts and parameter sweeping to determine setup/hold timing and voltage margins for high-speed parallel links. analyze parallel interfaces for compliance with timing and signal integrity constraints.

use the parallel link designer app to configure parallel links. set simulation parameters, specify corner conditions, and define stimulus patterns. set up pre-layout analysis to run spice and to conduct waveform and timing data analysis to analyze your custom parallel links. view and interpret the results using the signal integrity viewer app. you can also set up and analyze the post-layout pcb database of your parallel link design if you have a license for rf pcb toolbox™. you can modify the stackup and padstack models and customize vias and see how the changes impact your design.
