Specify a hold time, in nanoseconds, for input signals and forced reset input signals.
Default: 2 (given the default clock period of 10 ns)
The hold time defines the number of nanoseconds that reset input signals and input data are held past the clock rising edge. The hold time is expressed as a positive integer or double (with a maximum of 6 significant digits after the decimal point).
The specified hold time must be less than the clock period (specified by the Clock high time and Clock low time properties).
This option applies to reset input signals only if Force reset is selected.
This option is disabled if you select the entire model. Select the DUT instead for Generate HDL for setting.
Property:

| Type: integer |
| Value: positive integer |
| Default: 2 |
To set this property, use hdlset_param or makehdl. To view the property value, use hdlget_param.
Display setup time for data input signals.
Default: None
This is a display-only field, showing a value computed as (clock period -
HoldTime) in nanoseconds.
The value displayed in this field depends on the clock rate and the values of the Hold time property.
This option is disabled if you select the entire model. Select the DUT instead for Generate HDL for setting.
Because this is a display-only field, a corresponding command-line property does not exist.
