Signals window
7-148 ModelSim XE Graphic Interface ModelSim Xilinx User’s Manual
when you invoked the simulator. Multiple signals may be selected and forced; the
force dialog box remains open until all of the signals are either forced, skipped, or
you close the dialog box. See also the force command
(CR-56).
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
(CR-67).
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 "Projects and system
initialization"
(3-35).
