Hello, I have a GDS file of a chip, containing not the full chip but only some metal and via layers, since that's what I'm interested to simulate. When I import it to HFSS (providing as well the technology and layer map files) I get the warning: 

 [warning] GDSII Translation: 4 of 5 layers in the .gds file will not be imported.

Then in the 3D view I only see one of the layers, the rest are missing. Why is this hapenning? I hope you can help me. Thanks.

PD: I'm using Electronics Desktop 2024 R2.

Edit: to provide more info, I tried with the GDS of the full chip, around 1GB. Then in the importer window I add the technology & layer map files and I only select to import the last 2 metal and via layers, then HFSS gets stuck while taking almost 100GB of RAM, and it continues stuck for days.

HI, francisco.piernas.diaz, 

You can delete the configure folder from Documents\Ansoft\ElectronicsDesktop2024.2(your version)\config and re-start the ADET to see if it takes shorter to import the GDS. Once the system is busy and not response, please do no click on other things. If you are a conmercial user, please file a case for further assistance.

 

 

Best,

Rong
