@mohanad0mohamed Hello, Is it possible to let me know where did you find the gds files that you have here? I can't find these in the Skywater repository.

This LVS update contains:

• Adding VPP and RF devices in sky130.lvs.
• Adding patterns for some test cases.
• Including sky130.lvs inside sky130.lylvs.
• Merged to the latest commit of the repository.

This is related to https://github.com/KLayout/klayout/issues/1096

Currently, using a zero dimension for CellInstArray (either amax or bmax) will screw up the DRC engine and stream writers.

I will fix that (https://github.com/KLayout/klayout/issues/1098), but as of now, this patch will help.

I'm pretty sure there are other places where some array dimension is zero as well, but I did not have testcases for covering them.

Best regards,

Matthias

Trying to place a nmos, I get the following error (and nothing happens):

Hi ,

Trying to use a VIA - metal1 metal2 VIA. But Seems following DRC exists.

m2.5 [via_new] m2.5 : min. m2 enclosure of via of 2 opposite edges : 0.085um polygon: (0.425,-0.395;0.425,-0.245;0.575,-0.245;0.575,-0.395)

Thanks

Fixes #<issue_number_goes_here>

It's a good idea to open an issue first for discussion.

Status of this pull request:

• Completed all tests for all devices except the known issues which will be documented in Google Slides.
• Completed testing against all the Standard Cells. We still have some issues for certain cells that we have removed from the github actions for further investigation.

This fixes a bug where it tries to cast the default value to an integer

Our Magical team is currently working on supporting skywater-pdk to enable open-sourced tape out design. We have already finished the PMOS and NMOS device generation part, and are in desperate need of your support for the resistor and capacity LVS file to further boost the impact of both your open-sourced skywater-pdk and our Magical tool. Could you provide the resistor and capacitor LVS file? We also need parasitic extraction to generate the analog IC layout automatically.

Thanks for your help.

Hi. Your repo mentions that for most of the devices are verified by "semi-automatic". Does that include automated LVS scripts that extract resistor/capacitor devices? It seems that I am unable to find how res/cap are extracted in your LVS script: https://github.com/mabrains/sky130_klayout_pdk/blob/main/lvs/lvs_sky130.lylvs

Thanks for the help.
