Hi Silvano,
HyperLynx 6.1 has this new feature. After selecting a net on BoardSim, if
you click on File menu, one of the options is to export the selected net to
LineSim. The net will be exported as a LineSim file with all stack, net,
and driver/receiver parameters. Vias are exported as capacitors. In the
LineSim file, you can try various what/if scenarios. I have found this
features very useful.

Hi Ravinder, you said:
"I can also export nets from the layout (BoardSim) to LineSim, and then
carry out different what-if scenarios"
How do you do this ?
Many thanks,
Silvano
