Assignment Value Syntax
There are rules for using certain characters in assignment values to ensure the value is
legal. An unquoted value with only alphabetic, numeric, underscore (_), period (.) or
forward slash (/) characters is legal. A value containing any of the following
characters must be enclosed in double quotation marks (" ") to be legal.
{ } ( ) ; : , < >= - # "
In addition, values containing any of the following characters must escape the
character with a backslash:
{ } $ " \
For example, the following values are legal:
■ “EPF10K10LC84-3”
■ MODE1
■ “ModelSim (VHDL output from Quartus II)”
Although it is not required, you can also enclose assignments containing only legal
characters in double quotation marks.
