- >I need to know the following:
-
- >(1) What are these benchmark circuits ?
-
- They are combinational circuits. I think they are parts of, or
- complete, real designs. The number of Inputs and Outputs, and the
- complexity of the circuits varies.
-
- Usually referred to as ISCAS-85 circuits.
-
- There is a similar set of sequential circuits presented on ISCAS-89, I
- think.
-
- >(2) Where can I get these from ?
-
- I think MCNC - Microelectronics Center North Carolina - in the US is
- the correct address. I do not have any e-mail or other.
-
- It is an ASCII netlist, based on TEGAS TDL. Easy to transform to
- whatever format you need.
-
- They are free available, so if you know somebody with a copy, you may
- get a compy from them.
-
- (I may send you what we have, 8 of the 10 (?) circuits.)
-
- >(3) What is the Brglez & Fujiwara reference ( I could not locate it ) ?
-
- It is a tape, distributed to interested participants on the symposium.
- (And others later.)
-
- >(4) How can I use the above benchmark netlist to test a test generation method?
-
- A - Get a copy of the netlist
- B - Transform the netlist to the netlist_of_your_choise
- C - Run your ATPG
- D - Compare your results with other results. These you may find in
- conference proceedings or journals.
-
- >(5) Is there a updated version of this which has come out since 1989 ?
-
- They vere issued in 1985, 1989 was the year of the sequential
- circuits, if my memory serves me right.
-
- What is there to update on a netlist? These are supposed to be
- standard circuits which anybody may use to get comparable results from
- ATPGs or fault simulators. I hope nobody has changed them.
