Abstract
A method for manipulating security of an integrated circuit layout, comprising: rendering a PCell that is created by an original user for a successive user; providing an open access to the PCell; providing a PCell evaluator to execute evaluating steps of: getting license information from the PCell, and checking the PCell license information; and generating a layout of a sub-master by instantiating a super-master of the PCell if the PCell license information is valid, or leave the sub-master empty in a PCell view if the PCell license information is invalid.
Claims20
A method for manipulating security of an integrated circuit layout, comprising:
- rendering a PCell that is created by an original user for a successive user;
- providing an access to the PCell from a database;
- providing a PCell evaluator to execute evaluating steps of:
- getting a PCell license information from the PCell, and
- checking the PCell license information;
- and
- generating a layout of a sub-master by instantiating a super-master of the PCell if the PCell license information is valid, or leave the sub-master empty in a PCell view if the PCell license information is invalid.
A system for manipulating security of an integrated circuit layout, comprising:
- an application programming interface to render a PCell that is created by an original user for a successive user, and provide an access to the PCell from an OpenAccess database;
- a PCell evaluator to execute evaluating steps of
- getting license information from the PCell, and
- checking the PCell license information;
- and
- a layout generator to generate a layout of a sub-master by instantiating a super-master of the PCell if the PCell license information is valid.
