When I encrypt the IP using ipecrypt I get the following error:

Cipher initialization error '101167235'.

This is because the  directive data_method is missing or has invalid value.

Try with `protect data_method="aes128-cbc" or `protect data_method="aes256-cbc" for VHDL IP.

Use `pragma protect ... for Verilog IP.
