Reading and Writing Values Using TF Routines

Summary

This chapter has presented the routines contained in the PLI TF library, which are used to read and write the logic values of system task and system function arguments, and to specify the return value of a system function. The Verilog HDL provides a number of logic value constructs which do not have a direct counterpart in the C language, such as 4-state logic and vectors with arbitrary bit widths The TF routines provide several options for converting values from Verilog to C and from C to Verilog.

The next chapter is a continuation of the discussion of the TF library, and presents how to use the TF library with misctf routines.
