The
Force
dialog box includes
these options:
•
Signal Name
Specify the signal or net for the
applied stimulus.
•
Value
Initially displays the current value,
which can be changed by entering a
new value into the field. A value can
be specified in radixes other than
decimal by using the form (for
VHDL and Verilog, respectively):
base#value -or- b|o|d|h’value
16#EE or h’EE, for example,
specifies the hexadecimal value EE.
•
Kind: Freeze
Freezes the signal or net at the specified value until it is forced again or until it
is unforced with a
noforce
command (p332) .
•
Kind: Drive
Attaches a driver to the signal and drives the specified value until the signal or
net is forced again or until it is unforced with a
noforce
command (p332) . This
value is illegal for unresolved VHDL signals.
•
Kind: Deposit
Sets the signal or net to the specified value. The value remains until there is a
subsequent driver transaction, or until the signal or net is forced again, or until
it is unforced with a
noforce
command (p332) .
Freeze
is the default for Verilog nets and unresolved VHDL signals and
Drive
is
the default for resolved signals.
If you prefer
Freeze
as the default for resolved and unresolved signals, you can
change the default force kind in the
modelsim.ini
file; see "System Initialization/
Project File" (p413).
•
Delay
Allows you to specify how many time units from the current time the stimulus
is to be applied.
