university of moratuwa en۳۵۴۲ – digital system design hardware description languages i ajith pasqual pasqual@ent.mrt.ac.lk dept. of electronic telecommunication engineering b.sc. engineering semester ۵ module university of moratuwa references verilog for digital design – frank vahid verilog hdl – a guide to digital design and synthesis – samir palnitkar examples taken from digital design by morris mano university of moratuwa section ۱ contents introduction to hdl verilog combinational logic design digital design with verilog university of moratuwa hdl introduction hdl is a language that describes the hardware of digital systems in a textual form. it is a device independent representation. it resembles a programming language but is specifically oriented to describing hardware structures and behaviours. the main difference with the traditional programming languages is hdl’s representation of extensive parallel operations whereas traditional ones represents mostly serial operations. the most common use of a hdl is to provide an alternative to schematics. could be an asic fpga or cpld. university of moratuwa hdl – introduction ۲ when a language is used for the above purpose i.e. to provide an alternative to schematics it is referred to as a structural description in which the language describes an interconnection of components. such a structural description can be used as input to logic simulation just as a schematic is used. models for each of the primitive components are required. if an hdl is used then these models can also be written in the hdl providing a more uniform portable representation for simulation input. university of moratuwa hdl – introduction ۳ hdl can be used to represent logic diagrams boolean expressions and other more complex digital circuits. thus in top down design a very high level description of a entire system can be precisely specified using an hdl. this high level description can then be refined and partitioned into lower level descriptions as a part of the design process. university of moratuwa hdl – introduction ۴ a major reason for the growth of the use of hdls is logic synthesis. more later .. as a documentation language hdl is used to represent and document digital systems in a form that can be read by both humans and computers and is suitable as an exchange language between designers. the language content can be stored and retrieved easily and processed by computer software in an efficient manner. there are two applications of hdl processing simulation and synthesis hdl started as a simulation language. university of moratuwa advantages of hdl allows designers to talk about what the hardware should do without actually designing the hardware itself or in other words hdls allow designers to separate behavior from implementation at various levels of abstraction designers can develop an executable functional specification that documents the exact behavior of all the components and their interfaces designers can make decisions about cost performance power and area earlier in the design process designers can create tools which automatically manipulate the design for verification synthesis optimization etc. university of moratuwa hdl abstraction levels university of moratuwa which one to choose designers usually use a mix of all three early on in the design process they might use mostly behavioral models. as the design is refined the behavioral models begin to be replaced by dataflow models. finally the designers use automatic tools to synthesize a low level gate level model. university of moratuwa logic simulation this is the representation of the structure and behaviour of digital logic system through the use of a computer. a simulator interprets the hdl description and produces a readable output such as a timing diagram that predicts how the hardware will behave before its is actually fabricated. simulation allows the detection of functional errors in a design without having to physically create the circuit. errors detected during simulation can be corrected by modifying the appropriate hdl statements. university of moratuwa logic simulation ۲ the stimulus that tests the functionality of the design is called a testbench. to simulate a digital system design is first described in hdl verified by simulating the design and checking it with a testbench which is also written in hdl. university of moratuwa logic synthesis the process of automatically generating a gate level model from either a dataflow or a behavioral model is called logic synthesis this is the process of deriving a list of components and their interconnections called a netlist from the model of a digital system described in hdl. the gate level netlist can be used to fabricate an integrated circuit or to layout a printed circuit board pcb . logic synthesis is similar to compiling a program in a conventional high level language. university of moratuwa logic synthesis ۲ the difference is that instead of producing object code logic synthesis produces a database with instructions on how to fabricate a physical piece of digital hardware that implements the statements described by the hdl code. an hdl description of a system can be written at an intermediate level referred to as a register transfer language rtl level. using rtl a designer can show how the data flows between registers and how the design processes the data. details of gates and their interconnections to implement the circuit can be automatically extracted by logic synthesis tools from rtl description. caveat not all hdl code is synthesizable university of moratuwa logic synthesis ۳ university of moratuwa logic synthesis ۴ logic synthesis tool transforms an rtl description of a circuit in an hdl into an optimized netlist representing storage elements and combinational logic circuits. subsequently this netlist may be transformed by using physical design tools into an actual integrated circuit layout which serves as the basis for integrated circuit manufacture. the logic synthesis tool takes care of the large part of the details of doing a design and allows the exploration of the cost performance trade offs essential to advanced design. university of moratuwa logic synthesis ۵ the user provides an hdl description of the circuit to be designed as …
