Packed and UnPacked Arrays. Solved by kurts1 in post #2 When you declare an array, there are two types of dimensions: packed and unpacked. For example, imagine you have a variable that is 12 bits wide: bit[11:0] avar; Now, say that you want to treat these 12 bits as 3 groups ...
On this issue I'm reporting: A bug(?) I found when trying to declare a parameter as a packed array (note that issue #846 refers to unpacked arrays). A suggestion/request to improve the error message displayed on unsupported features. I w...
The suggested solution is not always acceptable: One problem with unpacked arrays is that you can't use them to interface between two modules. Is there any intention to support a packed arrays of packed struct in future Quartus releases? Has someone raised an SR? Tha...
Packed array flattening is fairly fundamental to how Verilator works, and while there might be some workaround possible to get the information, regardless there is no way in VCD format to express multidimensional packed arrays. wsnyder closed this as completed Oct 12, 2021 Member wsnyder ...

If you have fairly large arrays of structures, this option may save some space, but it trades off memory with runtime efficiency. In these examples, the additional keywords packed and unpacked are illustrated; many compilers achieve the same result with #pragma directives. Inflating Structures Two...
