PDMS - polydimethylsiloxane polymer.

  I have just found in manual that the input data file should look like
atom-ID; atom type; charge; x; y; z

well, there is more than just this one line format.
the read_data page lists the entire format. it is also
dependent on the atom style you choose.

In which software I will be able to make such input data file?

most people write their own scripts or programs to generate
data files. it is easy to do and in many cases it is difficulty
to write something that is fully generic. for example i have
written it as a plugin to VMD (which is bundled with VMD
these days) and it supports primarily systems that i care about:
