Replacing FPGAs with Low Cost ASICs

FPGAs Spartan 2

 

FPGA Conversion Break-Even 

We define a FPGA conversion break-even point as being the number of devices you need so that your savings equals the ASIC NRE investment.  Mathematically, this becomes:

Break-Even Volume =                     NRE Charge                      
                                          (FPGA Unit Price – ASIC Unit Price)    

For example, Tekmos has a 256-pin gate array, with 400K gates, 12 18K block RAMs, and 4 DCMs.  It will support circuits with a top clock rate of about 200 MHz.  Most of the FPGAs we see will fit on this array.  If the design fits on this gate array, then the following charges apply.

NRE: $49,000

 

FPGAs Spartan 2

The following table list Spartan 2 FPGAs, and the estimated breakeven volume for each part.  In general, if your volumes exceed the breakeven volume in 6 to 9 months, then an Spartan 2 FPGA conversion into an ASIC makes economic sense for you.
