Hello all.... Is there any script which does all the installation or any link for a preloaded virtual machine which contains all the tools for analog IC flow?

AFAIK no one shared virtual machine with pre-installed tools.

Not a VM in the strict sence but ready to use docker images (x86_64 and aarch64) : https://hub.docker.com/r/hpretl/iic-osic-tools

Thank you

unfortunately, there's no proper working script. those out there are old as a year or more and version control seems to be a problem with manual problem. best way is to get docker image. now the thing with docker is a bit hectic for new person. but once you are done with it. Its almost smooth, with some documentations lagging behind. i guess since this is open source project a site should be maintained with proper tool chain build up instructions docs..

Thank you Pritesh
