( SNUG 99 Item 42 ) ----------------------------------------------- [3/31/99]
HISTORY REPEATS ITSELF: Towards the end of SNUG'99 there was serious talk
about doing another design contest like the infamous 'Verilog vs. VHDL'
contest I held back in SNUG'95. In it contestants "were given 90 minutes
using either Verilog or VHDL to create a gate netlist for the fastest fully
synchronous loadable 9-bit increment-by-3 decrement-by-5 up/down counter
that generated even parity, carry and borrow." Of the 9 Verilog designers
in the contest, only one, Oren Rubenstein, didn't get a final gate level
netlist because he tried to code a look-ahead parity generator. Of the 8
remaining, 3 had netlists that missed on functional test vectors. (Kurt
Baty "claims" he "misfiled" his final results.) The 5 Verilog designers
who got fully functional gate-level designs were:
Larry Fiedler NVidea 3.90 nsec 1147 gates
Steve Golson Trilobyte Systems 4.30 nsec 1909 gates
Howard Landman HaL Computer 5.49 nsec 1495 gates
Mark Papamarcos EDA Associates 5.97 nsec 1180 gates
Ed Paluch Paluch & Assoc. 7.85 nsec 1514 gates
Of the 5 VHDL designers in the contest, *none* of the 5 succeeded in
getting their VHDL based designs to gates. -- and this caused all sorts
of reactions in the Verilog vs. VHDL wars.
What's being kicked around now is doing *another* 90-minute design
contest next year at SNUG'00. My problem is exactly *what* would be
a good, interesting problem for that contest?
"Yea! I want another chance to redeem my honor!"
- Oren Rubinstein of Gigapixel
"A followup on our lunchtime discussion. The problem is too little
time to work on an interesting design. But how about giving a
design that needs to go faster and has bugs in it? This may make
up for the difficulty in describing complex designs.
Maybe not bugs, but enhancements, more filter coefficients, more
memory or something like that. It would represent some of the
support issues that happen in real life.
To be really authentic, the testbench should have bugs too; but
that may be too hard again."
- Larry Fiedler of NVidea
"Those who cannot remember the past are condemned to repeat it."
- George Santayana, American philosopher, 1863 - 1952
