Gate Count Estimation

gate count estimation

Hello,

I don't have ASIC synthesis tool, but I have FPGA synthesis tool. I synthesis my RTL code according to FPGA synthesis tool. And I get the total number of logic cell used in this design. How can I transfer logic cell count to gate count?

BR,
NemOlee

register fpga gates estimate asic

Hi nemolee,

Just multiply the cell count by avg. no. of gate in NAND. I uses no. 4

estimate gate count

There is no strict relation between FPGA and ASIC gatecount. Depends on the utilisation of the FPGA components ...

well I remember reading somewhere that 1 ASIC gate ~= 8 FPGA gates....

ie a 1 M gate FPGA can hold a 200 k gates asic , if fully utilised.

Just multiply the cell count by avg. no. of gate in NAND. I uses no. 4

seems like he is saying about Transitor Count...

asic gate count

Please tell which synthesis tool you are using.

asic synthesis cell count gate count

Please tell which synthesis tool you are using.

The synthesis tool I use is Quartus II 4.2 and FPGA device is Cyclone II.
Thanks.
