IRdrop Analysis

yazdan

Hi,

 I am going to do both static and dynamic IRdrop analysis. During static analysis I encountered a problem. I need LEF-Tech Map file. Would you please describe me how I can get this file.

By the way, If you have any tutorial on IRdrop analysis and the flow of this process, I'd appreciate if you would send me.

 

Thanks

  • Here is an example LEF layer map:

      # LEF layer map: tech lefdef lef
    metal METAL_1 lefdef METAL1
    metal METAL_2 lefdef METAL2
    metal METAL_3 lefdef METAL3
    metal METAL_4 lefdef METAL4
    metal METAL_5 lefdef METAL5
    metal METAL_6 lefdef METAL6

    via CONT lefdef CONT
    via VIA_1 lefdef VIA12
    via VIA_2 lefdef VIA23
    via VIA_3 lefdef VIA34
    via VIA_4 lefdef VIA45
    via VIA_5 lefdef VIA56

    poly POLYCIDE lefdef POLY1

    You can find some documentation on IR Drop Analysis at the following link:

  •  Thanks for reply.

    So, you mean I should  write these file manualy by looking at technology file and lef file?

  •  Typically, this file should be provided by your technology library vendor. But if not, you can create it yourself.
