问题描述: packed array和 unpacked array,是我在SV里学到的概念。 但是在quartus syn的时候,会报错。 解决方法: 1. packed array的概念 2.以sv格式添加... 查看原文 Systemverilog语言(3)-------data types(1/2) ):表示位扩展信号,可以将每一位扩展为指定值;但是注意全1是不能扩展的,
1-D Packed and1-D Unpacked Array 下面是一个一维packed数组和1维unpacked数组的示例: module PU; logic [31:0] v1 [7:0]; //1-D packed & 1-D unpacked (memory) initial begin //Array Index 7 of unpacked v1[7] = 'h FF_FF_FF_FF; //equivalent to v1[7][31:0] $display(v1); ...
1. 维度在标识符前面的部分称为packed array,在标识符后面的部分称为unpacked array,一维的pakced array也称为vector。 packed array packed array只能由单bit数据类型(bit,logic,reg)、enum以及其他packed array和packed structure组成。packed array保证在内存中一定是一段连续的bit unpacked array unpacked array的元...
上面这个示例,是一个4*3*2个unpacked数组,其中每一个数据项都是一个8bit的packed数组。 如果每一个unpacked数据项使用1word存储,那么数组uP总的存储空间就是 4*3*2*1word 2-D Packed and 2D-Unpacked Array logic [1:0] [7:0] uP[3:0] [2:0]; 上面声明了一个2维unpacked 数组,每个数组项都是一...
I managed to figure out that this was due to issue #846 (Parameters having an unpacked array type is a SystemVerilog feature that isn't supported yet), but iverilog could at least try to figure out what I was trying to do and tell me that that's not supported; the error message as...
SystemVerilog 中有两种类型的数组- packed array 和 unpacked array。 packed array用于引用在变量名称之前声明的维度。 bit[3:0]data;// Packed array or vectorlogicqueue[9:0];// unpacked array packed array保证表示为一组连续的位。它们只能用于单位数据类型(如、和其他递归packed array)组成。bitlogic ...
And when I compiled it, I got an error: "Error (10053): Verilog HDL error at rom_sin.v(274): can't index object "MY_ROM" with zero packed or unpacked array dimensions" Please tell me why this error occurs and how to fix it. Thank you so much! Translate Tags: ...

array - same as component packed struct - 1 Unpacked Structures Memory layout for unpacked structures is governed by Golden Rules 1 and 2: • Golden Rule 1: The natural boundary for an unpacked structure is the natural boundary of its most demanding member. Padding bytes may be needed be...
Here's my SV packed array // dut.sv module dut (...); ... logic [8-1:0][16-1:0] mem_a; After verilator compilation I can see that it was flattened into 1 dimensional array // obj_dir/dut.h VL_SIGW(dut__DOT__mem_a,127,0,4); And the same in the VCD waveform $var...
