在SystemVerilog 中,unpacked arrays独立存储每一个元素,如: wire[7:0]table[3:0]; 其存储形式如下: SystemVerilog 也允许 unpacked arrays 简化成 size 的形式: SystemVerilog adds C-like arraydeclarationsto Verilog, allowing unpackedarraysto be specified with a dimension size, instead of starting and en...
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...

Is it possible to have a multidimensional array as a port in the Component Editor. If the answer is yet to Q2, how do I resolve this error? If the answer is no to Q2, how can I get around this without hardcoding the number of ports I need? T...
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...
all of these slices are illegal as they are not contiguous bits (packed), hence the syntax error you recieve, even when you use ranges that are valid for either of the array dimensions. Verilog/Systemverilog requires that the packed bit-vector slice is the right most bracketed range all...
