How can I change the "PCI I/O" setting using ECO? - How can I change the "PCI I/O" setting using ECO? Description In the Quartus® II software version 11.0 SP1 and earlier, the Resource Property Editor does not support changing the PCI I/O setting. To change the setting using an Engineering Change Order (ECO), use a Tcl script. The following code shows an example Tcl script for modifying the PCI I/O setting: load_package chip_planner project_open <project name> -revision <project revision name> read_netlist # This is to turn on "PCI I/O" setting for <I/O pin name 1> set_node_info -info "PCI I/O" on -node [get_node_by_name -name <I/O pin name 1>] # This is to turn off "PCI I/O" setting for <I/O pin name 2> set_node_info -info "PCI I/O" off -node [get_node_by_name -name <I/O pin name 2>] check_netlist_and_save To apply an ECO using the Tcl script, use the following command: quartus_cdb -t <Tcl script name> A future version of Quartus II software is scheduled to support changing the PCI I/O setting using the Resource Property Editor.
