The constant defined in the process can only be used in this process. The body section contains the actual implementation of the functions and procedures. Declarations other than values of deferred constants and subprogram bodies are not visible outside the package body and can be used only locally, DDR, a signal changes under a given set of conditions and otherwise remaunchanged. It is reasonable because Verilog is originally created for modeling and simulating logic gates. Package: hold the definition of commonly used data types, such as those available from ASIC vendors. The syntax of a package body follows.
