<<block-1>> inserts the body of block 'block-1'. <<block-1()> inserts
the *result* of evaluating block-1, and <<block-1(x=3.3)>> inserts the
result of evaluating it with the specified argument value. I've just
added documentation of this to Worg.

Can you provide the exact contents of the file you're having trouble
with? If I have

----------------------------------------------------------------
* test tangle
#+srcname: block1
#+begin_src python 
  x = 1
#+end_src

#+srcname: makefile()
#+begin_src python :tangle simulate_ofdm :exports none
  This is makefile
  <<block1>>
#+end_src
----------------------------------------------------------------

then for me org-babel-tangle produces

----------------------------------------------------------------
#!/usr/bin/env python
# generated by org-babel-tangle
# [[file:/tmp/zz.org::*test%20tangle][makefile]]
This is makefile
x = 1
# makefile ends here
----------------------------------------------------------------
