Your FPGA is
not too slow...
Your Design is!
FPGAs demand a
unique design style.
Good Field Programmable Gate Array design calls for a unique design style
to take advantage of the architecture. That's too bad, because most engineers will use the
same design style they've always used. Don't blame your engineer though, that's the way
he's been trained to think for the last three decades. See, an FPGA constrains a design in
ways most designers have never seen before.
Traditional design
styles will not perform well.
The FPGA structure limits the wiring between logic cells to a
small number of lines, where other technologies have few such constraints. The wiring in
an FPGA is also unique in that it adds large delays to the logic. An FPGA's high flip-flop
to logic ratio puts FPGA design in a class by itself too, since it favors using registers
over other logic. Even the cell architecture demands an unusual design style, and that
style varies between the different FPGAs. This means that FPGA designs done using
traditional styles won't perform well.
Andraka Consulting
Group
gets the maximum performance from an FPGA.
The Andraka Consulting Group understands FPGAs and the design
styles needed to make these devices perform at their best. An extensive background
in high speed pipelined signal processors and unmatched experience with FPGAs gets
you the performance you want.
Make your designs faster by:
 | Keeping them totally synchronous |
 | Avoiding synthesis for critical logic |

is done in our facilities on our equipment.
Andraka Consulting Group has Halved Logic,
A client was using two Xilinx XC4020E FPGAs and external
memory to compute vector magnitude. By using an alternate design approach, Andraka
Consulting Group, Inc. showed the customer how to obtain the same result with less than
half of one XC4020E while gaining almost four times the performance. The real-estate
savings helped to eliminate a whole board from the system.
Doubled Speed,
A terminal manufacturer presented us with a CRT display
controller implemented in a Xilinx XC3020 FPGA. He had stripped the design of most of its
bells and whistles to make it fit, and still had timing problems. By redesigning the
controller using our proven design philosophy, we were able to restore all of the extra
features and had a circuit capable of working at over twice the design clock rate. Our
design was so successful, that the client had us adapt it for a Liquid Crystal Display
controller.
And Done the
Impossible
Andraka Consulting Group successfully developed a video
concentrator in an Atmel AT6010 (a 10,000 gate array). The finished 80 MHz design utilizes
over 85% of the chip and is among the most complex designs (25,000 gates) ever attempted
in an Atmel FPGA. Engineers familiar with Atmel FPGAs and tools called this design
impossible because of the density and speed required.
