Hello, I keep getting this error when trying to harden my rtl for openlane which I'm not sure what to make of. Any guidance would be appreciated:

sometimes means that you ran out of memory. Does that make sense?

I see. Could you recommend any specific ways to check memory usage? Or any other steps to resolve this issue? Thanks!

@Vinay Ivaturi If your running native applications, I recommend

top

. If you’re running in docker, I’m not sure.

Thank you, I checked my memory usage and got past those errors. However I ran into this error in the routing step, which I am also confused about: [

Would it be related to memory again? I am unsure how to further optimize my design Thanks again

@Vinay Ivaturi How many GB of memory do you have?

child killed: kill signal

This often occurs when memory is exhausted. Can you increase your memory?

Thank you so much, I increased my memory capacity and it worked eventually. Sorry for asking a lot of questions, but I've also been getting this error regarding the macro placement which I'm still trying to figure out:

I’m guessing that it can’t find the mprj module in the verilog rtl.
