Detailed Description

Hierarchical layout optimizer for billion-scale designs.

Decomposes the problem into manageable IP blocks, optimizes each block separately, then optimizes block placement.

Member Function Documentation

add_component_to_block()

void zlayout::optimization::HierarchicalOptimizer::add_component_to_block	(	const std::string &	block_name,
		const Component &	comp )

Add component to an IP block.

add_net()

void zlayout::optimization::HierarchicalOptimizer::add_net

(

const Net &

net

)

Add net (automatically determines if inter-block or intra-block)

create_ip_block()

void zlayout::optimization::HierarchicalOptimizer::create_ip_block	(	const std::string &	name,
		const geometry::Rectangle &	boundary )

Create an IP block.

get_final_layout()

std::vector< std::pair< Component, geometry::Point > > zlayout::optimization::HierarchicalOptimizer::get_final_layout

(

)

const

Get final layout result.

optimize()

CostResult zlayout::optimization::HierarchicalOptimizer::optimize

(

)

Run hierarchical optimization.

1. Optimize each IP block independently
2. Optimize IP block placement
3. Refine with global optimization
