<p class="Element10">
Use vpi_control(), with one of the following operators and no other arguments, to obtain assertion system control information. </p>
<p class="Element10">
</p>
<p class="Element10">
Usage example: vpi_control(vpiAssertionSysReset) </p>
<p class="Element10">
vpiAssertionSysReset </p>
<p class="Element10">
discards all attempts in progress for all assertions and restore the entire assertion system to its initial state. Any pre-existing vpiAssertionStepSuccess and vpiAssertionStepFailure callbacks shall be removed; all other assertion callbacks shall remain. </p>
<p class="Element10">
</p>
<p class="Element10">
Usage example: vpi_control(vpiAssertionSysStop) </p>
<p class="Element10">
vpiAssertionSysStop </p>
<p class="Element10">
considers all attempts in progress as unterminated and disable any further assertions from being started. This control has no effect on pre-existing assertion callbacks. </p>
<p class="Element10">
</p>
<p class="Element10">
Usage example: vpi_control(vpiAssertionSysStart) </p>
<p class="Element10">
vpiAssertionSysStart </p>
<p class="Element10">
restarts the assertion system after it was stopped (e.g., due to vpiAssertionSysStop). Once started, attempts shall resume on all assertions. This control has no effect on prior assertion callbacks. </p>
<p class="Element10">
</p>
<p class="Element10">
Usage example: vpi_control(vpiAssertionSysEnd) </p>
<p class="Element10">
vpiAssertionSysEnd </p>
<p class="Element10">
discard all attempts in progress and disables any further assertions from starting. All assertion callbacks currently installed shall be removed. Note that once this control is issued, no further assertion related actions shall be permitted.</p></div>
