1. A computer implemented method for implementing dynamic protection of intellectual property in an electronic circuit design, comprising:

  • using a computer system that comprises at least one processor or process core executing one or more threads to perform a process, the process comprising;

    initiating an encapsulation process for a block of electronic design;

    creating a first parameterized cell instance for the block of electronic design with a first level of encryption of or access to the block of electronic design, wherein the first parameterized cell includes some design data about the block but does not by itself contain or obtain design data that are needed to construct details of the first parameterized cell instance of the block within a boundary of the block of electronic design by a parameterized cell evaluation module in an electronic circuit design tool; and

    encrypting a first set of design data associated with the first level of encryption or access in a first sub-master for the first parameterized cell instance with the first level of encryption or access.
