不过,虽然函数overload是一种好特性,但在SystemVerilog语言中是不支持的!下面是个会编译报错的栗子: 02 Overwrite 接着看overwrite,这是一个在SV中常常被忽略的一个类函数特性。overwrite可以简单粗暴地翻译成重写,毕竟“重写”两字的字面意思已经足够描述这一函数特性。 overwrite发生在子类和基类之间,即不同的类域之...
从Verilog到SystemVerilog的发展过程来看,两种语言都有其产生的必要性。Verilog在上世纪80年代中期产生,解决了当时一万门 以上设计面临的种种问题,Verilog的产生带来了门级设计到RTL级设计的变革,接下来的近20年,随着设计规模的扩大,Verilog也在不断的演 变和扩展,但是抽象层次始终徘徊在RTL级别;进入90年代以后,Verilog...

通读完了SystemVerilog for Design的各个章节,我最深刻的感受是自己对Verilog语言掌握得还很不够。毕竟,Verilog是SystemVerilog的基础,而我的基础又是很差的,只够应付当前工作的需要。riple 这本书中提到的对Verilog的扩展和改进的大多数内容虽然很吸引人,虽然很有道理,在实际应用中也确实方便和准确了些,但是只不过...
The existing UVM recording API relies on SystemVerilog function calls to record data values, but SystemVerilog function calls do not support function overloading – the ability to have a “f(int i) and an f(double d)”. This means that using function calls requires one function per data ...
