>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.
