Variables window
The Variables window lists the names of HDL items within the current process,
followed by the current value(s) associated with each name. The pathname of the
current process is displayed at the bottom of the window. (The internal variables
of your design can remain hidden if you wish, see "Source code security and -
nodebug" (p534).)
HDL items
y
ou can view
The following HDL items for VHDL and
Verilog are viewable within the Variables
window.
VHDL items
constants, generics, and variables
Verilog items
register variables
The names of any VHDL composite types
(arrays and record types) are shown in a
hierarchical fashion. Hierarchy also applies
to Verilog vector memories. (Verilog vector
registers do not have hierarchy because they
are not internally represented as arrays.) Hierarchy is indicated in typical
Model
Sim
fashion with plus (expandable), minus (expanded), and blank (single
level) boxes. See "Tree window hierarchical view" (p114) for more information.
To change the value of a VHDL variable, constant, generic or Verilog register
variable, move the pointer to the desired name and click to highlight the selection.
Then select
Edit > Change
from the Variables window menu. This brings up a
dialog box that lets you specify a new value. Note that "Variable Name" is a term
that is used loosely in this case to signify VHDL constants and generics as well as
VHDL and Verilog register variables. You can enter any value that is valid for the
variable. An array value must be specified as a string (without surrounding
quotation marks). To modify the values in a record, you need to change each field
separately.
