your question is far too open for people to respond. What I normally do is: • put everything in a public repo • write what you have tried so far in the README to keep the message here short and all the info in the same place • make sure you include the config.tcl file you've tried • make sure your source is included • include the log file for the detailed placer or at least the specific error message you end up with
then when I find the solution I update the repo and it becomes a useful resource for other people
