Hello,Regarding Terasoc's product, http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&no=941 I'm considering making a tiny little thing where Ethernet/UDP communication is time-critical, handled by the FPGA and not the HPS component. The DE0-Nano-SoC looks ideal, except I really dont need the ARM CPU... Does anyone know if the board supports routing the ENET pins to the FPGA directly? Grateful for any feedback on this, guys :) With Best Regards, Stride

An update from Terasic support:thank you for your e-mail.
the enth pins are connected to arm cpu pins, i am afraid it is impossible to modify the enth pins connection directly to the fpga.
free to contact us if you have any other question.
Hm, not cool :(

--- Quote Start --- Since you don't require the ARM core, perhaps the DE2-115 is better suited for your needs? http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&categoryno=139&no=502&partno=2 --- Quote End --- Thanks, I actually have one! It's a bit of an overkill for the solution tho. Basically I want to make a "no cpu" wirespeed UDP TX/RX chain for NTP, then feed "zero latency/jitter" data from a GPS. That tiny little DE0 device was almost perfect. Except for adding the HTS, CPU logic and the latence from it... Oh well. /Stride
