Abstract
Systems and methods to enable a user to edit subMaster content of selected instances of an electronic layout design, including editing the contents of selected instances of an existing subMaster of an EDA design, generating a new subMaster to incorporate the modified contents of the selected instances, and binding the new subMaster to the selected instances without losing the design hierarchy of the layout design.
Claims26
A processor-based method of editing cells of a layout design, the method comprising:
- creating, using a processor-based control system, a new parameterized cell (pcell) submaster from a first cell master of the layout design, the first cell master having one or more instances bound thereto;
- assigning, using the processor-based control system, one or more key parameters to at least one instance of the one or more instances to bind the at least one instance to the new pcell submaster;
- modifying, using the processor-based control system, contents of the new pcell submaster;
- and
- and and updating, using the processor-based control system, contents of the at least one instance according to the modified contents of the new pcell submaster when the at least one instance is bound to the new pcell submaster.
2 more elements
An electronic design automation (EDA) system, comprising:
- a control unit to create a new parameterized cell (pcell) submaster based on a first cell master, the first cell master having one or more instances bound thereto;
- and
- a graphical user interface to modify contents of the new pcell submaster such that the control unit assigns one or more key parameters to at least one instance of the one or more instances to bind the at least one instance to the new pcell submaster, modifies contents of the new pcell submaster, and updates contents of the at least one instance according to the modified contents of the new pcell submaster when the at least one instance is bound to the new pcell submaster.
