AndrewSftD · Answer

choice

AndrewSftD · Answer

AndrewSftD · Answer

but wire length does not matter right now at least in my mind

mehdi · Answer

Yes I didn t provide a merged gds < U016ULGAUNM> < U016EM8L91B> not sure if the script for that is ready

AndrewSftD · Answer

I think so

AndrewSftD · Answer

it was doing something last time

Tim Edwards · Answer

< AndrewSftD> The errors above come from reading the LEF views of the standard cells and then attempting to write GDS There are two ways to go about this correctly One is to do the full open pdks installation This creates magic style abstract views which are like LEF but have specific pointers to the GDS source so that the GDS for each cell can be found when writing the top level GDS the other way to go about this is to just read the GDS library first before reading the final DEF file output from OpenROAD so that the complete standard cell layout is available not just the abstract view part Always use gds readonly true before reading GDS from a known good non Magic source as it prevents Magic from messing up the layout by losing layers that it doesn t know about

AndrewSftD · Answer

hmm or KLayout in this case

20Mhz · Answer

which step is this I just deposited the individual GDS files into the platform gds folder may that will help ``` INFO Merging GDS files platforms sw130 gds sky130 fd sc hs a2111o 1 gds platforms sw130 gds sky130 fd sc hs a2111o 2 gds platforms sw130 gds sky130 fd sc hs a2111o 4 gds platforms sw130 gds sky130 fd sc hs a2111oi 1 gds ```
