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...

It allows users to define the pads for each layer in the stack-up as well as various mask layers, hole types, and slots. Validation Allegro PCB Librarian provides extensive part validation capabilities with built-in checks at every stage of the part creation process. For imported data, ...
Certain types of memory port may unconditionally assert ready, whereas other types of memory port may sometimes deassert ready depending on several factors. For example, a DDR SDRAM port is capable of buffering a certain number of commands internally, but if its command buffer is filled while it...
