I like to put all of these in src blocks and then use a sh block to run the actual simulation command. I usually put a :var a=(org-babel-tangle) header in the sh block, which makes sure the files are tangled, and then runs the shell commands. But this tangles all the files in the buffer, which is usually not what I want (there are sometimes multiple simulations described in one file). The blocks are not always in one subtree, so it isn't a matter of just narrowing, and they are mixed languages (text, make, python, etc.) and target files so I can't just target one file.

Use the :tangle header arg with your check function and its args:
:tangle (my-tangle-selector ...)
