1.3. Step 3: Implement Targeted ECOs
Run the provided Tcl scripts to implement the following ECOs:
| ECO Modification | ECO Command | Script |
|---|---|
| Modify the Lutmask | modify_lutmask | eco_demo_1.tcl |
| Change Routing Connections | make_connection | eco_demo_2.tcl |
| Tie Off Input Port to GND | modify_io_slew_rate | eco_demo_3.tcl |
| Modify Slew Rate, Current Strength, and Delay Chain | modify_io_delay_chain | eco_demo_4.tcl |
| Place A Node in a New Location | place_node | eco_demo_5.tcl |
| Create a Wire LUT Atom | create_wirelut | eco_demo_6.tcl |
As an alternative to the GUI methods, you can use the following commands to run the ECO Tcl scripts:
$ quartus_fit -s
load_package eco
project_open <project_name>
eco_load_design
...
eco_commit_design
project_close
