SystemVerilog 是 Verilog 的扩展,也用作 HDL。Verilog 具有和数据类型来描述硬件行为。由于硬件验证可能变的更加复杂和苛刻,Verilog 中的数据类型不足以开发高效的测试平台和测试用例。因此,SystemVerilog 通过添加更多类似 C 的数据类型和扩展 Verilog,以获得更好的封装和紧凑性。regwire 下图是 SystemVerilog 中可用...

Hello, I am having some confusion in understanding the purpose and usage of some SV and verilog data types. In verilog, what is the difference
This chapter describes the rich set of data types that SystemVerilog offers. Integer datatypes and real datatypes are discussed. In addition, use-defined types; static, local, automatic, and global variables; enumerated types; string data types; and event data types are discussed. Each data type...
