a question about defining layer in HFSS

[yfluo2004]

Hi ,

I am currently using HFSS to import the Cadence .gds file and verify the performance of the device. But could anyone tell me how to define the layer materials in accordance with the imported model? In the Cadence technology library, I found some files such as *.lay, *.slm, *.tf and *.layermap and so on. What kind of files I can use as the layer material definition in HFSS?

Thank you!

In the import options, you can define the height/thickness/properties of the layers using an attached file. Here is my file (with numbers changed):

layerfileall.tech:
6 shield red 0.0 0.0
21 mask1 tan 0.0 0.0
27 mask2 tan 0.0 0.0
34 m1 grey 500.0 500.0
35 via2 grey 1000.0 800.0
36 m2 grey 1800.0 500.0
37 via3 grey 2300.0 800.0
38 m3 grey 3100.0 500.0
66 mask3 tan 0.0 0.0
91 mask4 tan 0.0 0.0

After importing, you can select all elements whose names start with "m1" (for example) and assign them the appropriate properties for the 1st metal layer.

To get the material properties, use the thickness and resistance-per-square to calculate the necessary conductivity. Permeability=1 and I think you can assume permittivity=1 too.
