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,

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.

seems like he is saying about Transitor Count...
 

asic 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.
