This option is enabled by default. Add the flag
--include_virtual_input_pin_timing_in_bottom_up_scripts=off to disable.
--include_virtual_output_pin_timing_in_bottom_up_scripts[=on|off]
When this option is enabled, generated Tcl scripts contain OUTPUT_MAX_DELAY to constrain all paths
to the newly created virtual output pins (see --include_virtual_pins_in_bottom_up_scripts). Specify the
inter-partition delay seen by paths driven by the virtual outputs. For more information about the meaning
of theseassignments, please see the Quartus II Help topics relating to OUTPUT_MAX_DELAY.
The option is ignored if --include_virtual_pins_in_bottom_up_scripts=off is used.
If you use this option, you must also specify the delay (in nanoseconds) to be used in the constraints with
the --bottom_up_scripts_virtual_output_pin_delay=<delay> command.
This option is enabled by default. Add the flag
--include_virtual_output_pin_timing_in_bottom_up_scripts=off to disable.
--include_virtual_pin_locations_in_bottom_up_scripts[=on|off]
When this option is enabled, generated Tcl scripts contain location constraints on newly created virtual
pins (see --include_virtual_pins_in_bottom_up_scripts). The pins are locked to their top-level source (for
input pins) or sink (for output pins) location.
The option is ignored if --include_virtual_pins_in_bottom_up_scripts=off is used.
This option is enabled by default. Add the flag --include_virtual_pin_locations_in_bottom_up_scripts=off
to disable.
--include_virtual_pins_in_bottom_up_scripts[=on|off]
When enabled, this means that generated Tcl scripts contain commands to mark all lower-level pins that
connect to other design entities in the top-level (i.e. not directly to IOs) as virtual pins. This helps prevent
overuse of IOs and leads to a more accurate representation of the lower-level project.
This option is enabled by default. Add the flag --include_virtual_pins_in_bottom_up_scripts=off to
disable.
--incremental_compilation_export[=<.qxp file>]
Exports a design partition into a Quartus II Exported Partition (.qxp) file. The .qxp file contains the
compilation results of the specified partition, and can be imported into one or more design partitions of
another project.
The value <output file> is optional. If unspecified, the value specified by the
INCREMENTAL_COMPILATION_EXPORT_FILE global assignment is used if present. Otherwise, a
default file name is generated.
Other options you may use to control how the operation is performed include:
--incremental_compilation_export_partition_name[=<name>]
--incremental_compilation_export_routing[=<on|off>]
--incremental_compilation_export_netlist_type=<POST_SYNTH|POST_FIT>
Each of the above is explained in more detail in their own help sections.
