Uart core for a virtex-4

Hi,

I've been using the uart_tx and uart_rx core EDIF's provided by Xilinx in xapp223. These are great for my Virtex-II development, and they obviously don't work for the Virtex-4. I like the simplicity of these cores and want to change as little of my old code as possible. Does anyone know/have a free/$ replacement to these EDIF's that work for the Virtex-4?

Did you try generating same for Virtex-4 in Xilinx CoreGen?

Try to edit the EDIF, change the part in the edif with virtex4, and give it a try, it should retarget.

see Ken Chapman's old post pointing to the VHDL equivalent of the XAPP223 UARTS, which can be found in the Picoblaze sources:

as Ken Chapman's code. The old EDIF's are not reproducable for the V4 because of the architecture changes from V2 to V4. The souce code solves these issues.
