1.5. Evaluation Period Timeout Indicator

The Intel® Quartus® Prime software installation includes the ocp_timeout_indicator IP block in the libraries\others\opercore_plus\ directory. You can instantiate this IP block in your design to alert when the device times out.

Specify either an active_high or active_low polarity of the time-out signal (ip_timeout) with the timeout_indicator parameter.
