One big advantage of designing with Verilog is the ability to parameterize modules. You can design a generic adder and decide how many bits you need later. You can use the same parameterized adder as a 5-bit adder in one place and as a 64-bit adder elsewhere. Parameters are often used ...
In Verilog 2001, the code above will work, but the new feature makes the code more readable and error free. 1 module ram_controller ();//Some ports 2 3 ram_sp_sr_sw #( 4 .DATA_WIDTH(16), 5 .ADDR_WIDTH(8), 6 .RAM_DEPTH(256)) ram(clk,address,data,cs,we,oe); 7 8 endmodu...
Parameterized classes are same as parameterized modules in verilog parameters are like constants local to that particular class parameterized function task
Verilog-2001 adds a third and superior method to change the parameters on instantiated modules by using named parameter passing in the instantiation itself (see section 7). Example 4 - Module with four parameters The myreg module of Example 4 has four parameters, and if the module, when ...
Does anyone know a way to write a RAM in Verilog with parameterized width and byte enables that causes Quartus to infer a RAM block? Since Altera seems to be strongly discouraging direct use of altsyncram by removing all documentation, I am trying to find a way ...
SystemVerilog allows you to create modules and classes that are parameterized. This makes them more flexible, and able to work on a range of data types instead of just a single one. This concept is widely used in UVM, especially the uvm_config_db configuration database. Try these examples ...
The square root and logarithm modules are interconnected using an interface Valid/Ready present in AMBA AXI Protocol [1] and its architecture is described in Figure 3. The signals of its interface are described in Table I and depicted in Figure 4. Fig. 3. The SQRTLOG architecture TABLE I ...
The SystemVerilog UVM code determines the timing of the DPI calls. For example, in the PulseDetector SystemVerilog module: The "initialize" DPI call is triggered by an "initial" code block. The "terminate" DPI call is triggered by a "final" code block. ...
These graphical representations can then be processed to automatically generate the HDL of choice—VHDL or Verilog— in a form that is guaranteed to simulate and synthesize efficiently. The chapter also discusses the problems with coarse-grained architectures. The LPM_COUNTER function supports a number...
The normal Verilog parameter mechanism is used to parameterize a class: class vector #(int size = 1); bit [size-1:0] a; endclass Instances of this class can then be instantiated like modules or interfaces: vector #(10) vten; // object with vector of size 10 ...
