Hi,
Is there any body uses the Large FPGA to build test and measurements equipments. If you use it, how big is the idle FPGA for you.
thanks Narsi

I have. It was this big for me.

Sorry.
We build measurement equipment, but none of the FPGAs that we use are idle. Therefore I can't answer your question exactly. However, most FPGAs that we use are between 3cm and 4cm in size.

I am sorry, I meant IDEAL FPGA size in terms of density
I never know until the HDL is written and working in simulation. At that point, I can test the fit for any device I prefer.

I know Device programmers that used FPGAs ( smaller/older ones, on today's scales ) - these are mostly smart IO, and higher Voltage IO compliance matters.
I also know of oscilloscopes using FPGAs, - there they push things more, and need more logic, and less IO. Generic design is ADC + Memory + FPGA (+ some SW..)

They make a number of bus analyzers using FPGA's. In fact they tout the uploadable FPGA as a feature in the datasheets. In my experience the long start-up times due to configuration over a slow interface can be a drag. On the other hand I'm guessing their newer products have faster programming interfaces than the old serial stull I used in the past.
Cheers, Gabor
