| Description |
Entered by Charles Dawson on behalf of Debi Dalio. Her original email: Is there any equivalent VPI function that gives me the time of the next scheduled event like the PLI TF-function tf_getnextlongtime? I think that the diagram in section 26.6.40 implies that you get a handle to a vpiTimeQueue object and then call vpi_get_time() on it, but it doesn't actually describe this functionality anywhere that I can see. In fact, the description of vpi_get_time() talks only about getting the current simulation time using the time scale of the object. Am I correctly interpreting the time queue diagram? If so, I think there should be a description somewhere of what vpi_get_time() is supposed to do with this type of object. |

I propose the following change to the description of 27.12 vpi_get_time() FROM: The VPI routine vpi_get_time() shall retrieve the current simulation time, using the time scale of the object. If obj is NULL, the simulation time is retrieved using the simulation time unit. The time_p->type ... TO: The VPI routine vpi_get_time() shall retrieve the current simulation time, using the time scale of the object. If obj is NULL, the current simulation time is retrieved using the simulation time unit. If obj is a time queue object, the scheduled time of the future event is retrieved using the simulation time unit. The time_p->type ... |

From: "Garnett, Jim" <jimg@model.com> To: ptf-bugs@boyd.com Cc: Subject: errata/518: PROPOSAL - Modifying vpi_get_time description Date: Tue, 04 May 2004 09:48:18 -0700 There was a question as to whether vpi_get_time would return the time of a scheduled event if provided with an object of type vpiTimeQueue. The answer is yes, and the LRM currently describes this in section 26.4 Table 210 where it describes vpi_get_time as follows: Find the current simulation time or the scheduled time of future events The vpi_get_time description does not include any reference to what is returned when the 'obj' is a time queue object. Thus, I propose the following change in the description. FROM: The VPI routine vpi_get_time() shall retrieve the current simulation time, using the time scale of the object. If obj is NULL, the simulation time is retrieved using the simulation time unit. The time_p->type ... TO: The VPI routine vpi_get_time() shall retrieve the current simulation time, using the time scale of the object. If obj is NULL, the current simulation time is retrieved using the simulation time unit. If obj is a time queue object, the scheduled time of the future event is retrieved using the simulation time unit. The time_p->type ...
