Re: 3d VIA MODELLING USING HYPERLYNX V9.2
The differential 3d via modelling in linesim until release 9.2 was a bit simplified for a quicker response of the simulator. When I remember correctly you can see this when you look at the mode...

Re: 3d VIA MODELLING USING HYPERLYNX V9.2
Thanks for the reply.While converting obtained s-parameters to differential mode s-parameters then return and insertion loss are obtained as below. so i need to convert to convert to differential mode.

I already gave ports with lower reference.Can you please elaborate on addition of return vias effects.Thanks
View ArticleRe: 3d VIA MODELLING USING HYPERLYNX V9.2
No, you need to convert to mixed mode to see the mode conversion. I think when you open the geo file from linesim in MGRID you will see that it uses differential ports which internally ends up in a 2...

I'm not sure if I understood correctly. Are you looking for an introduction why stitching vias make sense?

The effect of extending ground to any area on the board - not just the edges - is dependent on your circuit design requirements. It's generally not a good idea to extend copper all the way to a board...
