Hi Rohith,

here some tips :

1. Is your custom IP very complex one ? Especially, does it use a lot of registers and/or rams ?

2. Your device must be a too little one for your IP. Try to change the device, and take a bigger FPGA and then launch the Synthesis.

3. Is your computer's ram enough for Quartus II tools ?

regards,

Hi Arriacinq,

yes, one of my module is SRRC filter with coefficient reload option , as per my observation it is mapping lot of ram instances during synthesis(am using Altera FIR IP core for this).

My Analysis & Elaboration completed in 2 hours, but synthesis taking lot of time(even after 15 hrs it is still 10% remained)

I am using Cyclone III 3c120f484I7 as my target FPGA

Thanks for your valuable suggestions.

Regards,

Rohith
