FUSION COMPILER APP OPTIONS

ECO Flow and Freeze Silicon Control

S.No	App Option	Description	Example
1	`design.eco_freeze_silicon_mode`	Enables ECO changes in the freeze silicon mode. Used when cell placement is fixed and only metal and via mask patterns can change. ECO design.eco_freeze_silicon_mode -value true	`set_app_options -name design.eco_freeze_silicon_mode -value true`
2	`eco.add_buffer_on_route.min_di stance_buffer_to_load`	Sets the minimum distance between the buffer and load when adding buffers on a routed net. Ignored when the -last_distance option is used. Not specified Not specified ECO eco.add_ buffer_on_route.min_distance_buffer_to_load -value 10	`set_app_options -name eco.add_buffer_on_route.mi n_distance_buffer_to_load -value`
3	`eco.placement.eco_enable_virtu al_connection`	Partial name due to line break in the documentation. Likely refers to eco.placement.eco_enable_virtual_connection, which enables virtual connection for repeater groups during ECO placement. Not specified ECO eco.placement.eco_enable_virtual_connection -value	`set_app_options -name eco.placement.eco_enable_virtual_connection -value true`
4	`eco.placement.eco_enable_pipel ine_register_placer`	Partial name due to line break in the documentation. Likely refers to eco.placement.e co_enable_pipeline_register_placer, which enables the pipeline register placer during ECO. Not specified ECO eco.placement.eco_enable_p ipeline_register_placer - value true	`set_app_options -name eco.placement.eco_enable_pipeline_register_placer - value true`
5	`eco.placement.first_track_alignm ent_layer`	Sets the first metal layer for track alignment checking in track_pattern mode during ECO placement. Not specified ECO eco.placement.first_track_alignment_layer -value M1	`set_app_options -name eco.placement.first_track_alignment_layer -value M`
6	`eco.placement.honor_cell_group _not_sharing_timing`	Honors variant cell groups that do not share the same timing view during ECO variant cell swapping. Not specified Not specified ECO eco. placement.honor_cell_group_not_sharing_timin g - value true	`set_app_options -name eco.placement.honor_cell_g roup_not_sharing_timing - value true`
7	`eco.placement.variant_cell_grou p_mode`	Sets the variant mode for different customers and design flows during ECO placement. Not specified Not specified ECO eco.placement.variant_cell_group_mode -value	`set_app_options -name eco.placement.variant_cell_group_mode -value`
8	`eco.placement.variant_cell_swap ping`	Enables the variant cell swapping feature before using add_group_repeaters and place_group_repeaters commands. Not specified ECO eco.placement.variant_cell_swapping -value true	`set_app_options -name eco.placement.variant_cell_swapping -value true`
9	`extract.starrc_mode`	Controls StarRC extraction mode. Used to enable or disable native extraction or specify In-Design extraction. fusion_adv fusion_adv, in-design, ECO	`set_app_options -name extract.starrc_mode -value partial`
10	`place.legalize.enable_advanced_ legalizer`	Enables the Advanced Legalizer to remove filler cells that have violations after legalizing ECO cells. ECO place.legalize.enable_advanced_legalizer -value true	`set_app_options -name place.legalize.enable_advanced_legalizer -value true`
11	`rail.database`	Sets the path for saving the RedHawk Fusion rail analysis results in the ECO Fusion power integrity flow. Not specified ECO RAIL_DATABASE_BASELINE	`set_app_options -name rail.database -value RAIL_DATABASE_BASELINE`
