Altera Set Virtual Pin

1, GUI way

We all know, assignment editor -> category -> logic options -> to -> virtual pin -> on;

2, tcl script mode

The basic architecture of the following links: https://www.intel.com/content/www/us/en/programmable/support/support-resources/design-examples/design-software/tcl/all_virtual_pins.html?wapkw=virtual+ pin

Tcl directly run the script is not enough, the following reference examples that can be run:

package require ::quartus::flow
load_package flow
   
proc make_all_pins_virtual {} {

    execute_module -tool map
   
    set name_ids [get_names -filter * -node_type pin]
   
    foreach_in_collection name_id $name_ids {
        set pin_name [get_name_info -info full_path $name_id]
        post_message "Making VIRTUAL_PIN assignment to $pin_name"
        set_instance_assignment -to $pin_name -name VIRTUAL_PIN ON
    }
   
    # Commit assignments
    export_assignments
}

make_all_pins_virtual
execute_flow –compile

An increase of 2 points Content:

(1) implementation process;

(2) at the start of the final script compiler;

Qii method in the script is run, enter the tcl console in: source xxx.tcl
