interface.Destination if_par ); endmodule This actually works.. It would require that at elaboration time any interface supplied to "if_par" would have to have a modort named "Destination", with any items re
Interface中的信号由Interface实例句柄访问。 Syntax Interface block在interface和endinterface关键字中间定义和描述。它可以像带或不带port的module一样实例化。 interface[name]([port_list]);[list_of_signals]endinterface interface还可以具有functions、tasks、variables、parameters,使其更像class template。它还能够通...
不过,在规模较大、抽象层次较多的设计中,处于枢纽地位的模块往往具有大量连线与外界的连通。为此,SystemVerilog引入了接口(interface)的概念,这个概念一方面减少了大量需要声明的端口名称,另一方面,它还方便设计人员将某些相关信号的通道作为一捆相对独立的线网组,这样就使复杂的设计更加简单、明晰。另一个概念是modport,...
Interfaces can contain tasks, functions, parameters, variables, functional coverage, and assertions. This enables us to monitor and record the transactions via the interface within this block. It also becomes easier to connect to design regardless of the number of ports it has since that information...
Virtual Interface One notable difference between an interface and a class is that interfaces can have ports. Another notable difference is that when instantiated,an interface is static; that is, an interface is compiled and then elaborated statically and permanently before the simulation runs. ...
WHat is an interface ? 如果设计包含数百个端口信号,则连接、维护和重用这些信号将很麻烦。相反,我们可以将所有设计输入输出端口放入一个容器中,该容器将成为 DUT 的接口。然后,可以通过此接口使用值驱动设计。 Waht is a driver ? 驱动程序是通过接口中定义的任务对 DUT 进行 pin-wiggling 的验证组件。当驱动器...
(this is also why we need virtual interface) Another thing is that wildcard import statement import pkg::*; doesn't import any identifiers (just make them candidates for import) until there is an explicit reference to that identifier. In addition to import, we can also export a package: ...
Verilator 是一个高性能 Verilog HDL 模拟器与 lint 系统,用户编写一个小的 C++/SystemC 封装文件,该文件实例化用户顶层模块的“已验证”模型
I can't quite read the examples you posted. In any case, we're using Parameterized SystemVerilog interfaces now in Vivado. We're still tweaking our use-cases - the latest release of Vivado (2015.3) is supposed to include some better support.
Verilator is invoked with parameters similar to GCC or Synopsys's VCS. It "Verilates" the specified Verilog or SystemVerilog code by reading it, performing lint checks, and optionally inserting assertion checks and coverage-analysis points. It outputs single- or multithreaded .cpp and .h files,...
