•通常一维数组用作memory模型表示,像reg [31:0]mema[0:255,]表示宽度32bit深度256的存储模型,仿真时可以使用$readmemh函数加载数据;而二维数组通常用于图像数据的表示,像reg[23:0] image[0:599][0:799]。 module data_type(); reg a;//标量 reg [3:0] b;//向量 wire[7:0] c;//向量 wire d...

Here, we have a SOC with a ARM multicore processor which talks to one of the peripherals, which is a flash memory (CODE FLASH and a DATA FLASH). The content of the paper discusses about the methodology used to verify such a SOC-based environment. Cadence OVM libraries are explored for ...

This extension uses the tags created using Ctags to provide many of its features. It is recommended to useUniversal Ctagsas it supports SystemVerilog also, compared to Exuberant Ctags and other older versions. The tags are stored in memory and not as separate files. ...
