Implementing randc behavior using regular constraints in SystemVerilog

Blogs, SystemVerilog and UVM / By

In SystemVerilog, variables declared with the randc keyword are random-cyclic variables that cycle through all the values in a random permutation of their declared range.  For eg: consider  a 2 bit variable declared as     randc bit [1:0] y; Every time this variable is randomized,  the values are iterated over the possible range (in this case 0,1,2,3)  …
