Volume of sale (i. e., the number of parts sold) is a factorwhen determining which device technology is to be used. Assume that a system can beimplemented by FPGA, gate array or standard-cell technology. The per part cost is$15, $3 and $1 for FPGA, gate array and standard cell respectively. Gate array andstandard-cell technologies also involve a one-time mask generation cost of $20,000 and $100,000respectively.
Determine the range of N for which FPGA technology has theminimal per unit
cost.

N has to be lesser than or equal to 1666.

Explanation:

Cost of parts N in FPGA = $15N

Cost of parts N in gate array = $3N + $20000

Cost of parts N in standard cell = $1N + $100000

So,

15N < 3N + 20000 lets say this is equation 1

(cost of FPGA lesser than that of gate array)

 Also. 15N < 1N + 100000  lets say this is equation 2  

(cost of FPGA lesser than that of standardcell)

Now

From equation 1

12N < 20000

N < 1666.67

From equation 2

14N < 100000

N < 7142.85

AT the same time, Both conditions must hold true

So N <= 1666 (Since N has to be an integer)

N has to be lesser than or equal to 1666.
