However, different versions of Yosys can be tested this way as well and should also result in failures, such as Yosys 0.9 or Yosys commit hashes 3333e00 or 70d0f38. + +However, to find failures in Yosys 0.8, a newer version of Yosys has to be used for the equivalence check. For this we can use Yosys master. An alternative for this is to use a simulator with a testbench, which is also supported by Verismith using Icarus Verilog. + -- cgit
