Additional … WebAll procedures in Verilog are specified within one of the following four Blocks. 1) Initial blocks 2) Always blocks 3) Task 4) Function The initial and always statements are enabled at the beginning of simulation. The initial blocks executes only once and its activity dies when the statement has finished.

http://www.asic-world.com/systemverilog/procedure_ctrl1.html WebVerilog, standardized as IEEE 1364, is a hardware description language (HDL) used to model electronic systems.It is most commonly used in the design and verification of digital circuits at the register-transfer level of abstraction. [citation needed] It is also used in the verification of analog circuits and mixed-signal circuits, as well as in the design of genetic circuits.

WebVerilog procedural statements are in initial or always blocks, tasks, or functions. SystemVerilog adds a final block that executes at the end of simulation.SystemVerilog final blocks execute in an arbitrary but deterministic sequential order. This is possible because final blocks are limited to the legal set of statements allowed for functions.
