Evaluate logical expression and stop simulation if false
assert( evaluates a logical
expression. Logical expressions evaluate to
false. If the
assert statement evaluates to
false, simulation stops and returns an error.
returns the specified error message string (
errmsg) for the failed
assert statement. If you run the test in the Test Manager, the error
message appears in the simulation log. If you run the test outside the Test Manager, the
message appears in the Diagnostic Viewer.
k are not 0, this
assert statement fails and simulation stops.
assert(h==0 && k==0)
assert statements can be used in the Test Sequence and Test
Assessment blocks and in Stateflow® charts.
assert in Model blocks works in Normal mode, but
not in Rapid Accelerator mode simulations.
When comparing floating-point data in
assert statements, consider
the precision limitations associated with floating-point numbers. If you need to use
floating-point data, define a tolerance for the assessment. See Floating-Point Numbers.
For example, instead of
assert(x == 5), assert
within a tolerance of 0.001:
assert(abs(x-5) < 0.001)
