Hello,<\/p>\n

 <\/p>\n

I would like to make a model of my cable FCC molex for integrating it to Circuit.<\/p>\n

 <\/p>\n

In my case, my rise time signals is 1ns, so my propagation delay is about 1,7\/c = 5,6ns\/m and for a length of 50cm, total delay is 2,8ns wich is not << 1ns… So do I need to use HFFS to get accurate values ??<\/p>\n

 <\/p>\n

In the doc, they say that it work if propagation delay is << than rise time.<\/p>\n

 <\/p>\n

Do you think Q3D will work ?<\/p>\n

 <\/p>\n

Thanks you very mich for your advice !<\/p>\n","protected":false},"template":"","class_list":["post-372079","topic","type-topic","status-closed","hentry","topic-tag-ansys-hfss","topic-tag-circuit-design-1","topic-tag-q3d-extractor"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
