Hierarchical large block synthesis (HLBS) filling

A computer program product for hierarchical large block synthesis (HLBS), the computer program product comprising:

• a memory;
• and
• a processing system configured to perform a method comprising:
• creating at least a partial ring around an HLBS structure to comprise at least one or more of filler elements, which are engineering change order (ECO) books for adding repeaters to wire dominated nets, and decoupling capacitors of relatively large sizes;
• identifying certain areas of the HLBS structure within the partial ring that exhibit a unique characteristic;
• disposing decoupling capacitors of the relatively large sizes in the certain areas;
• and
• filling a remainder of the areas of the HLBS structure with engineering change order (ECO) books and decoupling capacitors of relatively small sizes.

A system for hierarchical large block synthesis (HLBS), comprising:

• a memory having computer readable instructions;
• and
• one or more processors for executing the computer readable instructions, the computer readable instructions controlling the one or more processors to perform operations comprising:
• creating at least a partial ring around an HLBS structure to comprise at least one or more of filler elements, which are engineering change order (ECO) books for adding repeaters to wire dominated nets, and decoupling capacitors of relatively large sizes;
• identifying certain areas of the HLBS structure within the partial ring that exhibit a unique characteristic;
• disposing decoupling capacitors of the relatively large sizes in the certain areas;
• and
• filling a remainder of the areas of the HLBS structure with engineering change order (ECO) books and decoupling capacitors of relatively small sizes.
