2–96 Chapter 2: Command-line Executables
Compiler Options
Quartus II Scripting Reference Manual © July 2013 Altera Corporation
Compiler Options
Command-line compiler executables support the following options:
Option Page
-c=<revision name> ............................................................................................................................... 2–96
--rev=<revision name>.......................................................................................................................... 2–96
--set=<assignment=value> ................................................................................................................... 2–96
-c=<revision name>
Refer to the help for --rev=<revision name> on page 2–96
--rev=<revision name>
Option to specify which revision and its associated Quartus II Settings File (.qsf) to use.
This option directs the Quartus
®
II software to use the existing settings in the specified revision's .qsf, if
any. However, all arguments passed from command line and all assignments obtained from the database
override assignments from the .qsf.
If not specified, the revision name is assumed to be the same as that of the project. Altera
®
recommends
using the same name for the project and the revision to avoid the use of this option.
--set=<assignment=value>
Option to set a global assignment which does not belong to any entity. In general, global assignments do
not take a source or target.
By default, assignments are written to the Quartus II Settings File (.qsf) unless you specify
"--write_settings_files=off". An exception is the Compiler Database Interface (quartus_cdb), where
assignments are written to the QSF only if you specify "--write_settings_files=on".
For example, to ignore LCELL buffers during Analysis & Synthesis (quartus_map) type:
quartus_map chiptrip --set=ignore_lcell_buffers=on
To prevent the Fitter from chosing the optimal delay chain to meet tsu and tco timing requirements for all
I/O elements, type:
quartus_fit chiptrip --set=auto_delay_chains=off
Global assignments created or modified with this option are saved to the QSF.
For convenience, Quartus II command-line executables provide arguments for common assignments. For
example, to set the device family to Stratix for Analysis & Synthesis (quartus_map), type:
quartus_map chiptrip --family=Stratix
Otherwise, you'd have to type:
quartus_map --set=family=Stratix chiptrip
