LPA Flow in Innovus

PaSch

Hi there, 

we've encountered some strange behavior when trying to run the "check_litho" command from within INNOVUS 22.14. We set the required files and configuration files according to our PDK documentation. The command, without the absolute file paths, is:

check_litho -sign_off -cpu 96 -run_mode fg -create_guides -map_file <map file path> -config <config file path> -techfile <tech file path> -dir <output dir path> -write_stream_options "-mode ALL -merge <list of gds files>" -apply squishHints

We are currently using PEGASUSDFM 23.20 for this command but tested previous PEGASUSDFM and MVS versions as-well. After we issued the previous command, we see INNOVUS launching the PEGASUSDFM/MVS and trying to run the command. After some time, the command crashes with the error "mdb_load_with_extra: failed to pre-open extra input file './preproc/INTERMEDIATE.oas' for read". We have tested a similar setup with INNOVUS 19.10 where we did not have this issues. Did something change with the new INNOVUS version? Does anyone have an idea what we are missing? 

Thanks in advance.

Best regards,

PS
