How to Use the TF Routines

Summary

This chapter has presented the routines contained in the PLI TF library. A complete PLI application, called $read_test_vector, was presented, which used many of these routines. This application reads a test vector file from a file, and passes the value to the Verilog simulator.

The next two chapters are a continuation of the discussion of the TF library. They present how to use the TF routines to read and modify the values of system task/function arguments and how to use the TF library with misctf routines. The $read_stimulus example presented in the Chapter 12 is a more elaborate test vector reader, which can read values in any radix, and can read both the vector value and the simulation time to apply the vector from the test vector file.
