November 2007 DDR Timing Wizard User Guide
Using the dtw_timing_analysis.tcl Script
-ignore_move None Allows the script to run even though
the file name in the .dwz file had
changed. You should not use this
switch as you may get incorrect timing
margins. No
-ignore_phase_difference None Instructs the script to ignore the phase
differences found between DTW and
the Quartus II report. No
-ignore_version None Opens the project and analyzes timing
even though the version used by the
script does not match the project
version. No
-last_sdc_file <value> An SDC file name Allows the script to read other .sdc
files that might be pertinent to the
design. No
-name_filter <value> None Overwrites the timing paths the script
uses to extract the timing margin. The
script uses the Altera IP path names
*auk_ddr_datapath ,
*auk_qdrii_sram_datapath ,
and *auk_rldramii_datapath
for DDR2/DDR SDRAM,
QDRII+/QDRII SRAM, and
RLDRAM II interfaces, respectively.
No
-read_side ● tanrpt
● tq
● skip
● auto
Tells the script whether you want to
use Classic or TimeQuest Timing
Analyzer for read side timing analysis.
You also have the option to skip read
timing analysis. The default is auto,
which means that the script uses the
timing analyzer used to compile the
design. No
-rec_rem_margin_tradeoff
<value> Time value with unit Allows the script to take out margins
from the recovery/removal margin for
better postamble margin from read
margin. Default value is 0 ns. No
-sdc_file <value> ● auto
● dwz
● project
● an SDC file name
Indicates the location of the .sdc file to
be analyzed. The default value is the
.dwz file name indicated in the
-dwz_file switch.
No
