You deleted another file, not the symlink. If you do a 
ldd /usr/bin/sim
you'll see that the .so file isn't used, instead
/usr/lib/libsim.so.0.0.0
is used.

It is indeed a devel file.

In /usr/lib/libsim.so.0.0.0, there is a soname:
objdump -p /usr/lib/libsim.so.0.0.0 | grep SONAME
should give about
  SONAME               libsim.so.0
The libsim.so.0 is here such that you can have an idea about the 
soname without actually looking at the file binary headers.
The .so is used to link against the library file at build time.

If there is only a COPYING, then it is any version of the GPL. See
