How to Use the ACC Routines

Summary

The ACC routines in the PLI standard provide direct access to what is happening within a Verilog simulation. This access is done using an object oriented method, where most Verilog HDL constructs that can exist in a simulation data structure are treated as objects. The ACC routines use handles to reference these objects. A large number of ACC routines are provided to obtain handles for the various types of Verilog HDL objects, and other ACC routines retrieve data about the objects, such as the name of an object or the vector size of a net.

This chapter has focused on how to create PLI applications using the ACC library. The following three chapters will present more detail on the syntax and usage of the 103 ACC routines in the PLI standard. These chapters include several additional examples of PLI applications which use the ACC routines.
