Question

All objects in VPI have a vpiType. This API adds a new object type for data traversal, and two other objects types for object collection and traverse object collection.

/* vpiHandle type for the data traverse object */
#define vpiTrvsObj 800 /* use in vpi_handle() */
#define vpiCollection 810 /* Collection of VPI handles */
#define vpiObjCollection 811 /* Collection of traversable
design objs */
#define vpiTrvsCollection 812 /* Collection of vpiTrvsObj’s */

The other object types that this API references, for example to get a value at a specific time, are all the valid types in the VPI that can be used as arguments in the VPI routines for logic and strength value processing such as vpi_get_value(<object_handle>, <value_pointer>). These types include:

• Constants
• Nets and net arrays
• Regs and reg arrays
• Variables
• Memory
• Parameters
• Primitives
• Assertions

In other words, any limitation in vpiType of vpi_get_value() shall also be reflected in this data access API.
