for syn-thesis is realizability: they should only allow those behaviors that can be converted into an implementation to be described. As such, if a single language is used for both simulation and synthesis, then generally synthesis only supports a relatively con-strained subset of the language.

Verilog PLI(Programming Language Interface)是Verilog所提供的機制,我們可以使用C語言開發自己的system task/function,以彌補在Verilog撰寫testbench的不足。 在此文件,將學習到: 1.如何在Verilog呼叫C function? 2.如何撰寫簡單的calltf routine與register function?
assign a =0; assign b =1; always @(posedge clk)begin if(c) d <=a; else d <=b; end //assign e = a;//logic数据类型在表示线网时不支持线网类型的多重驱动特性。 //assign e = b;//多重驱动,编译报error:variable "e" is driven multiple structural drivers. //initial begin //f...
12. What is a Programming Language Interface? A Programming Language Interface in Verilog is a mechanism that allows interfacing with programming languages like C/C++ to enhance simulation capabilities or integrate Verilog with external tools.
