Checklist Before Building ========================= This checklist includes important items that the developer should check before building a CL Design Check Point (DCP) file for AFI generation. 1. Verify that the environment variables ``$HDK_SHELL_DIR`` and ``$CL_DIR`` are set correctly. 2. Verify that the ``$CL_DIR`` directory has a ``/build`` sub-directory. 3. Update ``$CL_DIR/build/script/encrypt.tcl`` script for your design specific changes, including the list of all the source files (including header files like .inc and .h/.vh), so they all get copied to ``src_post_encryption`` directory 4. Update the timing and placement constraints under ``$CL_DIR/build/constraints`` for your design specific changes.
