还是简单一些说吧,多维数组在Verilog中对应的硬件元素可以是存储器,向量,也即一维数组,可以认为是深度为0的二维数组。 由于能对应于硬件的数组,例如RAM,通常有这么几个参数,深度,宽度,因此我们一般做到二维数组,当然更多维的不是不可以,不违背语法,但用途极为有限。 例如: reg y1[11:0];// y is an scalar r...

int c[][$][int]; initial begin c= new[4]; // creates an array of 4 empty queues foreach(c[i]) repeat(i+1) c[i].push_back('{default:0}) end This creates a triangular shaped dynamic array of queues, where each element is an empty associative array. You can an assignment c...
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 Sing...
I've finally bitten the bullet and crossed over from VHDL to the dark world of System Verilog. I've got a testbench that causes Questasim (Modelsim) to throw the following error: # ** Error: (vlog-13069) C:/AirMattress/ARIN_Main/tb_top_beam.sv(571): near "[": syntax error,...

it is optimized to support the design of custom active FIS components using Layer Builder and models of photonic devices Lumeric INTERCONNECT and Verilog-A in Lumeric CML Compiler. Also in Lumeric, it became possible to directly transfer layout data between Virtuoso and FDTD/MODE, which allows ...
system verilog对经典的reg数据类型进行了改进,使他除了作为变量以外,还能被连续赋值、门单元、和驱动模块所驱动,这种改进的数据类型被称为logic。 它既可被过程赋值也能被连续赋值,编译器可自动推断logic是reg还是wire。唯一的限制是logic只允许一个输入,不能被多重驱动,所以inout类型端口不能定义为logic。不过这个限...
Most of the modules were implemented in hardware, using Verilog HDL, taking full advantage of the possible parallelization and pipeline, which allowed to obtain real-time image processing. The ARM processor is responsible for executing some parts of the algorithm, i.e. high-level image processing...
