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的元素数据...
189 Rotate Array 将数组循环顺移k个位置 Example 1: Input: [1,2,3,4,5,6,7] and k = 3 Output: [5,6,7,1,2,3,4] Explanation: rotate 1 steps to the right: [7,1,2,3,4,5,6] rotate 2 steps to the right: [6,7,1,2,3,4,5] rotate 3 steps to......
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...
For those that demand extra power, the ThinkPad P16 Gen 2 supports blazing-fast memory and high-performance storage. With power supply support of up to 230W, this mobile workstation can be configured to meet any need. And for the ultimate in connectivity, it has multiple ports for all...

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: ...
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...mysql安装和配置 mysql是是一款开源的数据库,很受欢迎!也是我经常使用的数据库之一,最近重装了电脑系统,顺便写一下mysql的安装配置步骤,方便以后翻看。
BGV-based schemes use in general slow operations, but they can treat a lot of bits at the same time, so they can pack and batch many operations in a SIMD manner, like in GPUs. Further, the set of operations that are efficient with BGV are very constrained by the parameter set. Some ...
Their defaults are 2Zn1 and 2Zm1; i.e., make the size of unpacked and packed structures a multiple of 1 (trivially true). In some cases, you may want to adjust sizes to be a multiple of a given value. For instance, to confirm a memory override during debugging, you may want to...
I had the same issue, and suspect it is simply an unsupported SystemVerilog feature in Quartus II. I was able to make an unpacked structure work. Make the following change to line 140: <line 140> packed_struct array_of_structs [10:0]; I hope this works for...
