SIMD指令与for循环相比,起码省了些"编译"(译码)时间。 Verilog里还可以`define AND asdp (4'b0000, // [Rd] = [Rn] AND (2nd operand) asdp是个task,而task不是软件工程师倾向于理解的task,而是返回多个值的函数: task will be introduced in Chapter 10 that is similar to the function command (又...
【SystemVerilog】define的一种用法 今天有用到define的一种用法,在这share一下,直接上例子~~ module top ; `define A_SRAM_RW(dst_cc_num,src_cc_num)\ if(strm_sel[``dst_cc_num``] == 1'b1)begin\ force top.my_dut.strm_in``dst_cc_num``_en = top.my_dut.strm_in``src_cc_num``_...
比如在LaunchPad上关于P1OUT,P1DIR ,P1REN ,P1IN等等,其实有时候我们只需要实现某一个功能,只不过在别的MCU上可能是两个寄存器参与,或者一个,或者三个,而在430上可能1个可能2个可能3个或者四个。由于寄存器功能可能定义不同,所以如果程序中出现了很多寄存器,那么当然就让人捉急了。 这时候一个伟大的东西出现...
#define MAX(x, y) ((x) > (y)) ? (x) : (y) 3. 定义单行宏:主要有以下三种用法. 1) 前加##或后加##,将标记作为一个合法的标识符的一部分.注意,不是字符串.多用于多行的宏定义中.例如: #define A(x) T_##x 则int A(1) = 10; //等效于int T_1 = 10; #define A(x) Tx##_...

The method is implemented by means of Cadence HAL software, Using Verilog procedural interface (VPI) to check Verilog code, Using VHDL procedural interface (VHPI) to check VHDL code, and using common front end procedural interface (CPI) to check common code. The user-define method of coding ...
Hello, I am working on a verilog project and I need to use some constants parameters in almost all of my modules. So, instead of defining them for every module, I was thinking it makes more sense to have a separate file with all the parameters and cons...
This only works in SystemVerilog saurabh_vlsi July 15, 2014, 8:35pm 13 In reply to : Hi Dave, I think the issue comes when the macros are used with generate loop. The complete code is : define WB_DUT_U_ASSIGN(phy_i,idx)\ assign b[phy_i] = DUT_PATH.Ilaneidx.a;\ genvar ...
一旦`define 指令被编译,其在整个编译过程中都有效。例如,通过另一个文件中的`define指令,max_bus_size 能被多个文件使用。 `undef 指令取消前面定义的宏。例如: `define word 16 //建立一个文本宏替代。 . . . wire [ `word : 1] bus; . . . ...
