"<config_file>
"
String that specifies the configuration file. Optional. Currently not supported, this argument
is ignored.
"<log_file>"
String that specifies the log file. Optional. Currently not supported, this argument is
ignored.
"<mtm_spec>"
String that specifies delay selection. Optional. The allowed strings are "minimum",
"typical", "maximum", and "tool_control". Case is ignored and the default is
"tool_control". The "tool_control" argument means to use the delay specified on the
command line by +mindelays, +typdelays, or +maxdelays (defaults to +typdelays).
"<scale_factor>"
String that specifies delay scaling factors. Optional. The format is
"<min_mult>:<typ_mult>:<max_mult>". Each multiplier is a real number that is used to
scale the corresponding delay in the SDF file.
"<scale_type>"
String that overrides the <mtm_spec> delay selection. Optional. The <mtm_spec> delay
selection is always used to select the delay scaling factor, but if a <scale_type> is specified,
then it will determine the min/typ/max selection from the SDF file. The allowed strings are
"from_min", "from_minimum", "from_typ", "from_typical", "from_max",
"from_maximum", and "from_mtm". Case is ignored, and the default is "from_mtm",
which means to use the <mtm_spec> value.
Examples
Optional arguments may be omitted by using commas or by leaving them out if
they are at the end of the argument list. For example, to specify only the SDF file
and the instance it applies to:
$sdf_annotate("myasic.sdf", testbench.u1);
To also specify maximum delay values:
$sdf_annotate("myasic.sdf", testbench.u1, , , "maximum");
