Expressions
• Signals that have the same file designator as the File option do
not need the designator added as a prefix to the hierarchy name.
• Signals from different file types (for example, VCD+ and EPIC)
cannot be mixed in the same expression.
Opening the Expressions Dialog
In the menu bar, click left on the Edit menu and choose Expressions.
Creating Expressions
To create a new expression:
1. Click left in the Name field and enter an expression name.
2. Choose a file designator from the File pull-down menu. (This field
is optional if the expression includes the full hierarchy name with
designators.)
3. Click left in the Scope field and enter the full hierarchy name of
the scope you are using for signal selection. For example:
Verilog
$V1$test.risc1.alu1 or $test.risc1.alu1
VHDL
$V1$test/risc1/alu1 or $test/risc1/alu1
Instead of typing, you can drag and drop a scope from the
Hierarchy Window into the Scope field. (This field is optional if the
expression includes the full hierarchy name.)
