Hello every body
When building my model, i have encountered this problem= Error: Invalid upper bound <0.0 in time-bounded until formula.
and when i check the manual i found that ." If type 7→ ctmc, and if the ‘Auto-time’ checkbox is not selected, the
value described in the ‘Time’ field will be provided as a parameter to the simulator engine
function. If the value is not a valid positive real number (> 0.0), an error will be given."
Can somebody help me?
Best regards
Gethin Norman

Fatima,
as the error states in one of the properties you are checking is a time bounded until formula where the bound is less than 0 which which is not feasible since time starts at 0.
