SystemVerilog优点一:你不必再纠结模块端口该声明为wire还是reg了(或更具体地,net还是variable)。有了SystemVerilog,你可以将所有模块端口和本地信号都声明为logic,语言会为你正确地推断出是net还是variable(可能偶有例外,工程师有时也可能希望明确地使用与推断结果不同的类型,但这种例外很少)。 请注意验证代码(verifica...
When we declare a static variable, we are telling our tools that we want the variable exist for the entire simulation. In contrast, when we declare a dynamic variable we are telling our tools that we want to limit the lifetime so that it only exists for as long as our task is executin...
UVMF_HOME– Set this environment variable to the UVMF 2023.1 installation path. MTI_VCO_MODE– Set this environment variable to64to use the 64-bit QuestaSim executable for UVMF testbench simulations. Other simulators must be compatible but the workflow is not shown in this example. Get setenv...
b2 = null; <---deallocate the second bustran object How do I create a variable shared by all objects of a class,but not make it global? static variable 1.The static variable is associted with the class definition , not the instantiated object 2.It is often used to store meta-data,su...

You could have a global variable that counts the number of objects of this type, but you are trying to avoid globals. The OOP solution is a static variable, where the storage is associated with theclassdeclaration, not the multiple objects that are constructed dynamically. ...
SystemVerilog 指的是 Accellera 对 Verilog-2001 标准所作的扩展。 在本参考手册中对 Verilog 语言的几个版本进行了如下的编号: Verilog 1.0 指的是 IEEE Std. 1364-1995 Verilog 硬件描述语言标准,也被称作 Verilog-1995; Verilog 2.0 指的是 IEEE Std. 1364-2001 Verilog 硬件描述语言标准,一般称之为 Veril...

SystemVerilog enumerated types are especially useful for coding state machines. An example of using an enumerated type as the state variable is shown below. typedef enum { IDLE = 2'b00, ACTIVE = 2'b01, DONE = 2'b10, XX = 'x
