Flash Memory Size Requirement

How to calculate the flash memory required for particular design.

I actually logged in for the same thing.. How to estimate this for a given number of logic elements?

Look for compressed and uncompressed bitstream sizes in your specific Altera FPGA datasheet. Then adjust for logic utilization. For example, multiply by 0.6 if your design uses 60% of the logic. 

This will give some rough flash size estimate.

Sryy for hijacking this topic.. 

 But how to estimate the ROM size for a given FPGA? Say if you have a 10k LE chip, and you want to put a ROM for that?
