Web2D Array of System Verilog Interfaces I'm using 2024.4 and though UG901 says that Array of Interfaces is Not Supported, I have been successfully using 1D arrays for a while now. Example: bus my_bus [2] (); However when I try to generate a 2D array of interfaces it fails in Elaboration. bus my_bus [2] [2] (); Any idea when this will be supported? WebThe code shown below simply shows how different arrays can be modeled, assigned and accessed. mem1 is an 8-bit vector, mem2 is an 8-bit array with a depth of 4 (specified by the range [0:3]) and mem3 is a 16-bit vector 2D array with 4 rows and 2 columns. These variables are assigned different values and printed.

WebSystemVerilog accepts a single number, as an alternative to a range, to specify the size of an unpacked array. That is, [size] becomes the same as [0:size-1]. In a list of multi dimensions, the rightmost one varies most rapidly than the left most one. Packed dimension varies more rapidly than an unpacked. http://duoduokou.com/csharp/16463877401854480811.html
