Replacing FPGAs with Low Cost ASICs

FPGAs Spartan 3E

 

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)   

 

FPGAs Spartan 3E List

The following table list Spartan 3E 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 3E FPGA conversion into an ASIC makes economic sense for you.
