INNOVUS APP OPTIONS

ECO Routing and Bump Connectivity

S.No	App Option	Description	Example
1	`setNanoRouteMode -route_with_eco`	Enables incremental (ECO) routing mode so that globalDetailRoute only routes newly added or modified nets without rerouting previously routed nets	`setNanoRouteMode -route_with_eco true`
2	`setNanoRouteMode -route_connect_to_bumps`	Enables routing connections from TSVs and front bumps directly to instance pins in 3D stacked die designs where there are no IO pads	`setNanoRouteMode -route_connect_to_bumps true`
3	`setNanoRouteMode -route_selected_net_only`	Restricts nano route to route only selected nets; used in interposer designs for front bump to front bump routing	`setNanoRouteMode -route_selected_net_only`
4	`setNanoRouteMode -route_selected_net_only`	Restricts NanoRoute routing to only the selected nets. Used in 3D stacked die designs to route specific nets connecting TSVs and bumps to instance pins	`setNanoRouteMode -route_selected_net_only true`
5	`setNanoRouteMode -route_connect_to_bumps`	Enables nano route to connect routes to bump pins; required for front bump to front bump routing in interposer designs	`setNanoRouteMode -route_connect_to_bumps`
6	`setFlipChipMode -constraintFile`	Specifies a constraint file for same-layer interleaved shielding during 3D IC routing. The file defines shielding width, spacing, style, and net	`setFlipChipMode -constraintFile fc_shield.const`
7	`setNanoRouteMode -route_inter poser_interlayer_shielding_offset s`	Establishes the offset (in technology units) between centerline of signal wires and centerline of interlayer shielding wires for specified routing layers in interposer designs	`setNanoRouteMode -route_interposer_interlayer_shielding_offsets {METAL1 2.8 METAL3 2.8}`
8	`setNanoRouteMode -route_inter poser_interlayer_shielding_nets`	Defines interlayer shielding net assignments for 3D IC routing. Specifies which shielding net to use for shielding wires within a specified layer range	`setNanoRouteMode -route_interposer_interlayer_shielding_nets {METAL1:METAL4 VSS}`
9	`setNanoRouteMode -route_inter poser_interlayer_shielding_width s`	Establishes the routing width (in technology units) of interlayer shielding wires for specified routing layers in interposer designs	`setNanoRouteMode -route_interposer_interlayer_shielding_widths {METAL1 2.0 METAL3 2.0}`
10	`setNanoRouteMode -route_inter poser_interlayer_shielding_layer s`	Specifies which routing layers receive interlayer shielding wires and their position (above or below) relative to signal routing layers in interposer designs	`setNanoRouteMode -route_interposer_interlayer_shielding_layers {METAL2 bottom METAL4 bottom}`
