Hi Neel, Sorry about the mistake.
Actually I am trying to implement FFT in the Ettus RX-TX Path. Building the code along with the FFT takes much more time as expected. Is there a way to specify incremental place and route in Xilinx? I am hoping that this time can be reduced for small changes in the code, so that when rebuilding, I can use the old build files. -- Thanks and Regards Shoor From: Neel Pandeya <neel.pand...@ettus.com<mailto:neel.pand...@ettus.com>> Date: Friday, October 13, 2017 at 4:47 PM To: Shoorveer Singh <shoorveer.si...@privoro.com<mailto:shoorveer.si...@privoro.com>> Cc: usrp-users <usrp-users@lists.ettus.com<mailto:usrp-users@lists.ettus.com>> Subject: Re: [USRP-users] Fast synthesis of SDR's FPGA Hello Shoor: Please keep the conversation on the mailing list. A build time of 20 minutes for the B200mini FPGA is entirely normal. I'm not sure how much you would be able to reduce that. Again, try the build on a system with a higher clock speed and at least 8 GB memory. Our Xilinx ISE workflow does not have an incremental build process, and because Xilinx has ended development and support for ISE (Xilinx has deprecated ISE), we do not have any plans to add this capability. Please let me know if you have any further questions. --Neel Pandeya On 13 October 2017 at 10:43, Shoorveer Singh <shoorveer.si...@privoro.com<mailto:shoorveer.si...@privoro.com>> wrote: Hi Neel, I am using USRP B200mini.

Which USRP device are you using? The primary thing would be to use a CPU with a higher clock speed. More memory helps too, as the build process is memory-intensive, but only up to a point. For the B200/B210 FPGA, a system with 8 GB memory should suffice. Xilinx ISE won't really take advantage of multiple cores, so using a CPU with lots of cores won't help much. --Neel Pandeya On 13 October 2017 at 09:34, Shoorveer Singh via USRP-users <usrp-users@lists.ettus.com<mailto:usrp-users@lists.ettus.com>> wrote: Hi, I am trying to modify the Ettus’s FPGA code and build the new code to get the bit file. But it takes a very long time for every build to be done. I am using Xilinx ISE for this work. Is there any way I can get it to work faster? -- Thanks and Regards Shoor _______________________________________________ USRP-users mailing list USRP-users@lists.ettus.com<mailto:USRP-users@lists.ettus.com> http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com
