Hi all, One of our interns at Mabrains has created this video on how to create and verify a layout using klayout PDK, Please find the link to the Arabic version below: And Also, please find the PDK at: https://github.com/mabrains/sky130_klayout_pdk We will release the English version soon. Thanks @Ahmed Elbadry

Hi @Amro Tork , quick feedback . In last MPW6 we tried to use the via generator. But some issue was happening at prechecks. In the GDS it was creating a hierarchy for the vias and naming it (ok i guess) , but the prechecks was compares to the verilog hierarchy. Will be great if someone can test if the same issue is there or not. I agree this might be a efabless issue , but i dont have the infrastructure right now to replicate. Thanks

@Ryan Wans That's the issue with Magic. The best solution to flatten the design.

@Amro Tork - yes finally we had to flatten too. Thanks

@Ryan R Glad to help

I would not recommend people flatten their design unless they really can't avoid it. (and I say this as someone who flattened both my submissions on MPW 1 and 2). Best to try and get efabless to fix the issue @jeffdi @Tim Edwards @Mitch Bailey

@yrrapt We only did that for the precheck. Internally in our design process, we use hierarchical database.

We’re talking about using the via generator at the top level with hand drawn layout, right? Do you see a problem if you add a level of hierarchy - put all your via’s in

user_analog_proj_example

, for instance. @yrrapt I believe the connection check has been fixed in the precheck.
