In reply to abhirula:

Ok, your question makes more sense now. SystemVerilog multi-dimensional arrays are more like arrays of arrays. That means you have to deal with each dimension separately, and each elements that is an array needs to be sized.

class A;
   
   rand bit [11:0] width [];
   rand bit [11:0] height [];
   
   rand bit [11:0] rows_cols [][];
   
   constraint width_cst {
      width.size() inside{[100:5]};
      height.size() inside {[200:700]};}
   
   constraint c {rows_cols.size() == width.size();
      foreach(rows_cols[ii])
		 rows_cols[ii].size == height.size();
   }
   constraint each_element {foreach(rows_cols[ii,jj])
			    rows_cols[ii][jj] inside {[1:255]};}endclass
