The ISCAS '85 Circuits


The following table presents some of ISCAS '85¹ benchmarks selected for the the BIST lab work. All of them are pure combinational circuits. You (or your teacher) should choose three of them to make your experiments. We recommend to choose the first circuit among the two first ones. The second circuit can be chosen among the following three benchmarks and the third one - among the last three benchmarks. Please, take a look at the example.

The last column in the table shows recommended -count option values for the BIST emulator. This means, for instance, that the emulator should be run with maximum -count 8000 for c5315 circuit. Otherwise the emulation will take too much time. On the other hand, for c880 circuit this value must be at least 10 000. Otherwise the fault coverage achieved by the emulator will be too low. This information is provided here for you as a recommendation only. It is aimed at making your work faster. In fact, you can choose acceptable -count values by yourself.
