about it. In fact, in fact, it is just hard to describe the speech, you must first use e-phones to think, and then use code to represent the e-phones. B. OpenGL:After learning about the hardware architecture, we started to use the RTL language of the language. C. Mega function:This is also a major feature of this article. In this example, we will use the mega function provided by Altera to compile the design, so that you can naturally learn the mega function built in Quartus II. Conclusion

The popular abdominal language artist is willing to reveal at the scene the performance of the man who was murdered by his partner, the abdominal language artist who took the soul. God is willing to really fall into the multiple personality, ordered to kill his wife and son of the puppet personality appeared. In order not to kill (let himself) the wife who had an affair with his disciple, the day would have offered the Commission to want to monitor, but the next morning, and the son really kille

Below are the instructions in the help documentation for the official website Quartus.A state machine was a sequential circuit that advances through a number of States. By default, the Quartus II software automatically infers state machines in your Verilog HDL code by finding variables whos E functionality can is replaced by a state machine without changing the simulated behavior of your design. If you wish

When VHDL calls the Verilog module, add "VERILOGMODELGM:" Before instantiating the module. VHDL Call Verlog: Verilog module://verilog Port declaration in the underlying file Module M (a,b,c); Input A, B; Output C; ... The Endmodule call is as follows: Compoent m--VHDL The original example in the top-level file Port A:In std_logic; B:in std_logic; C:out Std_logic

1.var/reg and Bit/logicVaryReg--> is used to declare registers in Verilog HDL;Var--> all the temporary resources in the SV are considered as variables, i.e. variable;With:Both Reg and VAR consume FPGA resources.Note:The REG keyword is retained in the A.SV, and Reg is equivalent to Var.B.SV also uses the var keyword when declaring ram.Example:reg [3:0] RLED; Verilogvar [3:0] RLED; Sysverilog2, physical characteristics register generally has 4 states, n

I can't wait to write these things myself. This chapter is essential for the development of hardware. Besides, we have to develop a CPU. ~ ~ often see someone released what Verilog code god Horse, feel very cow. In fact, you can also learn to. Manual up, follow along. In the previous chapters, we learned to design a variety of line diagrams, with levels of abstraction ranging from high to low, functional block level, logic gate level, MOS tube leve

0. IntroductionThe Verilog PLI (programming Language Interface) is a mechanism for Verilog code to call C + + functions. It allows Verilog to invoke the user-written C + + function like a system call (such as $display/$stop/$random). PLI can perform the following functions: Power analysis Code Coverage tools Modify the

From RTL view to Verilog languageOnce heard that a certain Daniel said: "When you learn the FPGA to a realm, you see the hardware description language, will no longer be a simple language, but by a logic door composed of the circuit diagram, once reached this realm, can write code to the extreme!" ”The author is how to hope to achieve this realm AH ~ ~, but this realm to the author's feeling is so illusory.Some time ago I wrote a blog titled "Error-pr

Module Module Introduction The module is the basic unit of the Verilog HDL language, and the digital system is described in the form of a module. A module is an external port that describes the functionality, structure, and communication of other modules of a design. Each module in the Verilog HDL is run in parallel Modules can invoke instances of other modules Module struct

1. as a hardware description language,Verilog can directly describe the hardware structure, but also by describing the system behavior to achieve modeling, its main features and functions are:* describes basic logic gates and basic switch models. * allow user-defined primitives. * You can specify the port-to-port delay in the design, the path delay, and the timing check in the design. * Models can be modeled in a variety of ways, including (1) Sequent

This article mainly introduces Verilog if (0), if (1) to Verilog syntax correction function. Verilog syntax is too simple, has always been our criticism of the place, want to achieve a function sometimes you have to knock on a large section of the function of repeated code snippets, sometimes just one of the parameters change. This time lazy we will come up with

The variables in the Verilog HDL language are only two categories of data types, wire and register Reg. The network cable type represents the physical connection between Verilog HDL structured components, whose value is determined by the value of the source device that drives it, and the default value of the network cable is high impedance z if no drive source is connected to the network cable. The

can improve the portability and readability of the program.5) macro definition is to replace a string with a macro name, that is, to make a simple permutation, not a grammar check. Pre-processing is still the same, regardless of the meaning is correct. The error only occurs when compiling a source program that has been expanded by the macro.6) macro definition is not Verilog HDL statement, do not need to add semicolons at the end of the line. If a se

Design and simulation verification of integer multiplier based on Verilog HDL1. Pre-KnowledgeIntegers are divided into short integers, medium integers, long integers, and only short integers are involved in this article. Short integer: Occupies a byte space,8 bits, where the highest position is the sign bit (the maximum bit is 1 is negative, the highest bit is 0 is a positive number), the value range is -127~127 . Negative numbers are represented by p

1. The question was raisedProject A is a soft core, written in VHDL, the synthesis of the time to remove the "Add I/O buffers", and-IOB (Pack I/O registers into Iobs) set to No. The A.NGC file was finally generated for use by other projects. After NGC is generated, the appropriate call file can also be generated in the View HDL instantiation Template "Design Utilities".Project B calls the A.NGC, but Engineering B uses Verilog to write, and at the time

One: Generate Verilog-2001 adds a generate loop that allows multiple instantiations of module and primitive, as well as multiple variable,net,task,function,continous assignment, Initial and always. In generate statements, if-else and Case statements can be introduced and different instantiations are produced according to different conditions. Usage: 1. Generate syntax has generate for, genreate if and generate case three 2. Generate for statement must

In a digital system, the information is often transformed into bits of binary code, because the data is processed using binary operations. In a logic circuit, the signal is output in the form of a high, low level. Encoder: The implementation of coded digital circuit, the input of each high and low level signal into a set of corresponding binary code. A 3-bit binary encoder with an input of 8 active high signals and an output code of the original code output is designed. Simplified logic express

language implementation　　With the above discussion, it is easy to implement a branch predictor using Verilog HDL.It is worth noting that only the saturation counter is incremented or decremented for non-overflow, and the highest bit of the count value is used to determine if a jump occurs, and 1 is taken,0 to not taken.1 ModuleBpu2 #(3 parameterPCW = -,//The width of valid PC4 parameterBTBW =Ten,//The width of BTB address5 )6(/*Autoarg*/7 //
