module mod_a ( input in1, input in2, output out ); // Module body endmodule 模块的层次结构(hierarchy of )是通过在另一个模块中实例化(instantiating)一个模块来创建的,只要使用的所有模块都属于同一个项目(这样编译器就知道在哪里找到模块)same project (so the compiler knows where to find the mod...
我们注意到log里warning非常有规律:Duplicate port/net name "xxx" found in module "xxx",这样我们可以用正则提取net和module名字。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 dup = {} for line in log: # Warning: Duplicate port/net name "N528" found in module "frc_pat_test_1" while...
Inside this particular top module are two things: a clock divider and an AND gate. But notice the clock divider block also contains a number of smaller blocks (DFFs). We DO NOT have to create all these DFFs in our top module; we can create a separate clock divider module that contains...
Add support for $finish(0/1) Support parse for specparam( just ignored) Handle only one module for duplicate top module with warnings GUI Add drag& dtop style zoom Add Center mode in zoom mode Correct caption for zoom mode Improved parsing for console jump function 3.50...
MakeFunction (D) Construct a function definition from an expression and inject random function calls to this function in the module containing that expression. DuplicateModule (D) Make a renamed copy of a module that is instantiated multiple times and redirect a subset of the instantiations of thi...
After `including class A into each package, you wind up with two definitions of class A.Using `include is just a shortcut for cut and pasting text in a file.Importing a name from a package does not duplicate text; it makes that name visible from another package without copying the defini...
To take a simple example, if a task-function has common code for two different monitors and for two different interfaces, a DV engineer mostly adds duplicate code in both the monitors. There are many other cases where we see code duplication. “System Verilog Macro” is one of the m...

If you connect output ports by name instead of order, they can be of any type. Output a is a wire type: module example_a_module( output a ); endmodule Here b is a 10 bit reg type: module example_c_module( output reg [9:0] b ...
run_test启动uvm验证平台 在这种情况下,UVM会利用UVM_TESTNAME从命令行中寻找测试用例的名字,创建它的实例并运行,如下所示的代码也可以启动my_case0: 整个UVM验证平台启动及执行的...类会提供run_test()方法充当UVM世界的核心角色,通过UVM_top调用run_test()方法。 2)在环境中输入run_test来启动UVM验证平台,run...
