FPGA: reuse code library

[jyang72211]

I am thinking about creating a library of reusable host subvi for fpga application.  To communicaiton with the FPGA VI, the host vi would contain a FPGA reference, and it is generally a good practice to make that a type def (is that correct?).  When I create a reusable subvi, the reference input will not be a type def, and when I feed a type def into the terminal, I will get a coercion.  Is that the only way?

Does it mean I just need to select dynamic mode in configure open fpga vi reference?  What role does the dynamic fpga interface cast play?  Thanks!
