Is there any particular reason why verilator doesn't allow 'real' typed numbers when using the power (i.e. '**') operator? The SystemVerilog standard says that real numbers should be allowed. It's actually done that way so that it matches the behavior of the C library's pow() functi...

Using Parameters in Verilog/VHDL and SystemC 支持在Verilog或VHDL和SystemC之间的参数。在Verilog中为SystemC实例指定的参数值将自动传递到SystemC域。 Parameters in Verilog 在Verilog中支持的参数类型为有符号和无符号整数,以及real数据类型。对于SystemVerilog,也支持string参数类型。参数是模块声明的一部分,如下: ...
SystemVerilog introduces an object-oriented class data abstraction. Classes allow objects to be dynamically created, deleted, assigned, and accessed via object handles. Object handles provide a safe pointer-like mechanism to the language. Classes offer inheritance and abstract type modeling, which brings...
Design complexity is ever increasing with multi-mode, statistical timing analysis, multi-vt/VDD low power and multi-core performance based type of designs. IEEE 1800 System Verilog (Ref 1) is a natural smooth transition language to Verilog (Ref2 and 3) for system level design and verification...
A third example of Verilog X optimism is how Verilog and SystemVerilog treats transitions to X or Z. The following are all valid logic transitions that will trigger aposedgeoperator 0->1, 0->X, 0->Z, X->1, Z->1 A 0->X or X->1 transition may or may not be a realposedgetransi...
