1. ► vpiNoDelay is the only type of delay which can be specified in vpi_put_value.

2. ► Simulation times in VPI are represented two 32bit numbers put together to form a 64bit number.

3. ► vpi_scan extracts only one element from iterator as obtained using vpi_iterate.

4. ► vlog_startup_routines is a function which is called by simulator to register routines.

5. ► vpiBinStrVal is the slowest of the format for retrieving values from simulation kernel using VPI.

6. ► Valgrind can check memory issues with arrays e.g. out of bound access.

7. ► vpiSysTfCall returns the handle to the task or function call which occurred in Verilog and in turn called this C/C++ routine.

8. ► Iterators obtained using vpi_iterate can be rewinded using VPI routines.

9. ► Calling vpi_control(vpiStop) will terminate the simulation.

10. ► All properties are defined for all kinds of handles.
