WHICH SOFTWARE CAN FIND PARASITICS ON A PCB?

[bbbb]

Hi all,

I wonder if anybody know a software that can determine the parasitics on a PCB. That is, after drawing/routing a PCB, I want to find the capacitance of some sensitive traces to GND plan (or resistance between two points on a trace).

Thanx in advance

Allegro does it.

you can sue the tools from ansoft, Q3D (be careful with the wavelength and trace length ratio), HFSS and 2D extractor. if you need help using this tools don't hesitate in asking. hope this help.

too many softwares can do it, just your preference to choose them.
