Compiling and Elaborating Your Design

Making Accessing an Out of Range Bit an Error

Condition

By default it is a warning condition if your code assigns a value to, or

reads the value of, a bit of a signal, or an element in a memory or

multidimensional array, that was not in the declaration of the signal,

memory, or array.

For example:

reg [1:0] r1;

initial

r1[2] = 1;

In this case, there is no bit 2 in the declaration of reg r1. VCS displays

a warning message but continues to compile the code and link

together the simv executable. The following is an example of this

warning message:

Warning-[SIOB] Select index out of bounds

in module module_name

"source_file.v", line_number: signal[bit]

You can use the +vcs+boundscheck compile-time option to tell

VCS to make accessing a bit or element that is outside the declared

range to be an error condition, so that VCS does not create the new

simv executable.

The following is an example of the error message VCS displays when

you enter this option and access an undeclared bit:

Error-[SIOB] Select index out of bounds

in module module_name

1 2 ... 123 124 125 126 127 128 129 130 131 132 133 ... 148 149
