Matching CDL file with GDS file is impossible with these 17 cells:

  • sky130_fd_sc_hd__conb_1
  • sky130_fd_sc_hdll__conb_1
  • sky130_fd_sc_hvl__conb_1
  • sky130_fd_sc_hs__fill_diode_2
  • sky130_fd_sc_hs__fill_diode_4
  • sky130_fd_sc_hs__fill_diode_8
  • sky130_fd_sc_hs__conb_1
  • sky130_fd_sc_ms__fill_diode_2
  • sky130_fd_sc_ms__fill_diode_4
  • sky130_fd_sc_ms__fill_diode_8
  • sky130_fd_sc_ms__conb_1
  • sky130_fd_sc_ls__fill_diode_2
  • sky130_fd_sc_ls__fill_diode_4
  • sky130_fd_sc_ls__fill_diode_8
  • sky130_fd_sc_ls__conb_1
  • sky130_fd_sc_lp__diode_0
  • sky130_fd_sc_lp__diode_1

Due to there are some devices (diodes or resistors) need to have marker layers to be extracted thus the CDL files will need to include them as devices.

Example:

Solution:
These devices should have the marking layer associated with each device to be extracted.

Another issue: There is a layer called "236/0" found in most of the standard cells and isn't documented in the documentation.
