I am encountering an issue where EMX cannot read or display Metal 8 and Metal 9 layers in the layout view. Metal 6 appears correctly.

I am encountering an issue where EMX cannot read or display Metal 8 and Metal 9 layers in the layout view. Only Metal 6 appears correctly.

Reproduction Steps & Observations:

  • I am attempting to simulate an inductor designed on Metal 8. When generating the EMX view, Metal 8 is missing entirely from the layout (see attached screenshot: With_Metal8.png). 

To isolate the issue, I changed the inductor from Metal 8 to Metal 6. After this change, EMX correctly recognizes and displays Metal 6, and the simulation produces expected results (see attached screenshot: With_Metal6_.png).

I am using following software versions.

  • Tool: EMX (version: 6.2)
  • PDK/Technology: TSMC 65nm
  • Cadence Virtuoso version: IC6.1.8-64b.500.21

This is my first time working with EMX so I have no idea what where I am going wrong.
