what I want to do is display the current nibble when load is set to '1' and not change the display when load is set to '0'. I must be thinking about this all wrong. If you have any insights into my confusion,

//ADC_CIRCUIT is an User-Defined Primitive for //Analogto Digital Converter for example. Verilog 中一些低级内置门基元的 VHDL 等效项可以通过使用逻辑运算符如 NOT、AND、NAND、OR、NOR、XOR、XNOR 来实现。 下面是 Verilog 门基元的 VHDL 等效代码示例: ...
The quickest way to verify the parameter values is to compile (build) the design, then navigate through the resulting graphical design hierarchy tree which shows the computed values of the parameters for each IP instance. You can search for all instances of a module in a tree by entering the...

(2) items that are defined inside of a package are not permitted to make hierarchical references to items outside of that package. (this is also why we need virtual interface) Another thing is that wildcard import statement import pkg::*; doesn't import any identifiers (just make them can...
Now that we have defined a hierarchy, we can reference any named Verilog object or hierarchical name reference, by concatenating the names of the modules, module instance names, generate blocks, tasks, functions, or named blocks that contain it. Each of the names in the hierarchy is separated...
Functional coverage is a user-defined metric that measures how much of the design specification, as enumerated by features in the test plan, has been exercised. 个人理解: 衡量验证激励完备性及场景完备性的一个标准,Functional_coverage可以检查
