Hello everyone, when I run qflow on my verilog design it creates a folder named "layout" where you have .gds and .mag files which you can open in magic and view, however when I try to do this then I do not see the standard cell gates and on the console window it says that it is unable to read them, what could be the issue.

Is there a way to launch the OpenRoad GUI using openlane makefiles so that it includes the STA constraints? (I'm not sure if this is "built in"... I know I could do it through scripting...)

Hi all, Any ideas to solve my hold violation problem?

Hey all, I am having trouble installing klayout on my Ubuntu 24. I just used “sudo apt install klayout” and when I “klayout -v” it outputs “Klayout 0.28.15” However when I try to open klayout by “klayout”, it runs a few processes and then proceeds to say core has been dumped. I tried to install from the klayout website, but I keep hitting dependencies issues with libgit2-1.1, libruby3.0 and libpython3.10

Does anyone know how I can open klayout with the pdk? I am trying with the following command:

Hello. I'm using xschem with gf180mcu PDK. There are many digital stdcells I can use in xschem with SKY130 PDK. But I couldn't find them in xschem with gf180mcu PDK. Should I manually design latches, flip-flops, etc. to use them? or is there any sources that I can use in xschem? Thank you for reading my question.

@Stefan Schippers, I was looking to do mixed signal simulation in xschem. I was wondering if there is a way to import verilog(.v) file in xschem or can i create verilog file in xschem and is there any documentation for writing verilog code in xschem??
