Hi all,
I am fairly new to EM field simulation. I am trying to simulate a 4-metal layer laminate with drilled vias - the bottom metal is GND. All my vias are shorted together. The objective is to quantify the inductance between the via top metal and the bottom GND plane. Please see the attached model in the zip file.
When I define the lumped port as going from the top via to the bottom GND metal, HFSS stops with an error: port refinement, process abc3d died unexpectedly.
Is this because I am drawing the port through the dielectric and 2 intermediate metal layers ?
How would I go about correcting this model ? Any comments/suggestions/advice will be greatly appreciated.
