VPI : vpiLoad iterator on vpiIntVar

GaneshAMBA

According to the IEEE Std 1800-2012, VPI code should be able to determine the variable loads of a vpiIntVar or vpiIntegerVar using the vpiLoad relationship iterator. The relevant section is 37.17 of the specifications (page 954).

However, with Xcelium 2017.10.005, VPI code attempting to use that relationship prints out the following error:

ERROR: VPI NOTOTI
The operation vpi_iterate(vpiLoad, ...) is not supported for a reference handle of type vpiIntVar.

Given that the simulator doesn't seem to support a feature that is legal according to the LRM, does anyone have pointers on how VPI code can determine the loads of a particular integer variable in the SystemVerilog source ?
