import_aux

Imports the specified auxiliary file into the design. Equivalent to executing the Import Auxiliary Files command from the File menu.

import_aux -format file_type -top_level_name top_level_name [-merge_timing] filename

Arguments

-format file_type

Specifies the file format of the file to import. You can import one of the following types of files: pdc, sdc, pin, dcf, saif, vcd, or crt.

-top_level_name top_level_name

Specifies the instance name of your design in the simulation testbench when you import a VCD or SAIF file.

Note: To identify the top_level_name for SAIF and VCD files, refer to Importing a VCD file and Importing a SAIF file.

-merge_timing value

Specifies whether to preserve all existing timing constraints when you import an SDC file. Same as selecting or unselecting the "Keep existing timing constraints" check box in the Import Files dialog box. The following table shows the acceptable values for the this option:

Value	Description
yes/true	Designer merges the timing constraints from the imported SDC file with the existing constraints saved in the constraint database.
no/false	The existing timing constraints are replaced by the constraints in the newly imported SDC file.

filename

Specifies the name of the auxiliary file to import.

Supported Families

Fusion, ProASIC3/E, ProASICPLUS, Axcelerator, ProASIC, MX, eX, SX/SX-A

Description

Auxiliary files are not audited and are handled as one-time data-entry or data-change events, similar to entering data using one of the interactive editors (for example, PinEditor or Timer).
If you import the SDC file as an auxiliary file, you do not have to re-compile your design. However, auditing is disabled when you import auxiliary files, and Designer cannot detect the changes to your SDC file(s) if you import them as auxiliary files.

Exceptions

None

Examples

import_aux -format sdc file.sdc

import_aux -format pdc file.pdc
