ID:12100 Entity cannot be used because entity name "<name>" contains tilde (~) character. Tilde (~) character can be used only for Compiler-generated primitive names

CAUSE: You used a tilde (~) character in the specified entity name in a design. However, the tilde (~) character has a special meaning in the Quartus Prime software, and cannot be used for entity names; the character can be used only for primitive names generated by the Compiler.

ACTION: Do not use the tilde (~) character in entity names. Make sure that you use only legal name characters in the entity name, such as alphanumeric characters.
