not recommendedindicates that a course of action is unsuitable, but not prohibited. There may be reasons to use other options, but the implications and reasons for doing so must be fully understood.
typedef enum { K_CLASS, K_FUNCTION, K_METHOD, K_VARIABLE, K_NAMESPACE, K_MODULE, K_UNKNOWN, K_PARAMETER, K_LOCAL_VARIABLE, COUNT_KIND } pythonKind; SystemVerilog is one of the parsers that use keywords and kinds mixed-way. I think this mixture makes improving the parser harder (wit...
26. What is Parameter and Typedef in Verilog? A parameter is a constant value within the module structure used to define various attributes for the module. It also characterizes the behavior and physical representation of the module. Typedef Enables users to craft unique names for type definitions...
example uses bit-stream casting to model a control packet transfer over a data stream: typedef struct { shortint address; reg [3:0] code; byte command [2]; } Control; typedef bit Bits [36:1]; Data Types A data type is a set of values and a set of operations that can be ...

可以通过使用内置的系统函数$isunknown来检查表达式的任意位是否为X或Z。这个函数返回一个布尔值,指示给定表达式是否包含未知状态(X)或高阻态(Z)。例如,可以在一个always块中使用这个函数来监控信号的状态,并在必要时采取行动。 40. What is the Difference between param and typedef? param和typedef有什么区别?
