Layer File for klayout ?

[ratul619]

Hi ,

in the GDS files i see new layers - are the layer files ".lyp / .lyt " released in any area ?

Thanks

No KLayout config exists yet. Someone will need to create one based on the documentation which can be found at https://sky130-fd-pr-reram.readthedocs.io/en/latest/user_guide.html

@mithro Ok

I have further confusion about the PDF layers.

1. When i load the GDS file : rram_cell.gds inside cells directory , i see the cell is built with below layers. Referring to the layer table & the shared link - i can make out below ? Is the following table correct ?

68/5 : BE txt
68/16 : via (connected from RRAM top electrode to met2)
68/20 : cviam
68/44 : r1c
69/5 – TE text
69/16 : r1v
69/20 : via (connected from RRAM bottom electrode to met1)

2. Also not able to make out the layer refer to layer # 221/20 ? What is the use of this layer ? Boundary only ?

Thanks

@ratul619 : Layer 201:20 (edit: fixed typo in layer number) is the ReRAM. The rest of the layer:purpose pairs are standard sky130 assignments. Your table is pretty much all wrong.

68/5: metal1 text
68/16: metal1 pin
68/20: metal1
68/44: via1
69/5: metal2 text
69/16: metal2 pin
69/20: metal2

@ratul619 @RTimothyEdwards did you mean 201:20?

@proppy : Yes, that was a typo. 201:20.
