1.3.6. Create a Wire LUT Atom
You can specify the create_wirelut command to create a multiple of wire LUT atoms.
Follow these steps to create 3 wire LUTs from inputa_4_reg[0] by running the eco_demo_6.tcl Tcl script.
- In the Timing Analyzer, click Reports > Custom Reports > Report Timing.
- Under Targets, specify inputa_4_reg[0], inputb_4_reg[0], and inputa_4_reg[1] for From.
Figure 19. Report Timing Targets
- In the Timing Analyzer, right-click inputa_4_reg[0], and then click Locate Path > Locate in Resource Property Viewer.

- In the Node Selection pane, select node i11 under Arrival Data. You can view the node i11 as the COMBOUT in the Top Combinational list. The inputa_4_reg[0] node connects with the DATAE port.

- To add a wire LUT from the targeted node, click Processing > Start > Perform ECO Compilation. Specify and run eco_demo_6.tcl. eco_demo_6.tcl contains the following create_wirelut ECO command:
create_wirelut -name my_delay_wirelut_1 -from inputa_4_reg[0] \ -to i11 -port DATAA -location "X23 Y61 X23 Y61" create_wirelut -name my_delay_wirelut_2 -from inputb_4_reg[0] -to i11 \ -port DATAD -location "X23 Y61 X23 Y61" create_wirelut -name my_delay_wirelut_3 -from inputa_4_reg[1] -to i11 \ -port DATAC -location "X23 Y61 X23 Y61" - Repeat steps 1 through 4 to view the change in Resource Property Viewer.
