I am simulating a VHDL design using ncsim / simvion and I get an odd error Error: VHPI NULLOBJ NULL reference vhpiHandle supplied to routine vhpi_handle(). The following message was reported while SimVision was accessing design data: Error: VHPI NULLOBJ NULL object vhpiHandle supplied to routine vhpi_get(). it is not hurting simulation operation, still I am scay it can hide something that may hit afterward (e.g. synthesis) Obviously I cannot find what is the reason (ncsim does not help reporting more info about the root cause of it ... Any hidea? Thanks much
