Hi all, There's an instance of BRAM in spartan3 device. I used coregen with *.coe file to init the data for the memory module My question, is there anyway to edit the mcs file (we use flatform flash for config) to change the content of init data ..."without spend 20 minutes to re-run the whole ISE processes Thanks,
Update init data in dualport BRAM without re-run anything?

But I'm not sure I can get anything, Is there any download-able thing ? Thanks

From a random sell sheet: ISE=99 WebPack FPGA Design Tool Suite =95 Timing driven FPGA hardware implementation tools =95 Design entry, synthesis and verification capabilities =95 Data2MEM =96 application for loading on-chip memory It looks like it's included standard.

Guessing it's just another non-user-friendly Xilnx apps ;-) Thanks

It would be nice if they supplied both GUI and command-line tools, but if they're only going to do one or the other, I'd far rather have the command line tool than a GUI tool. I can trivially invoke a command line tool from my software Makefile, but it's a serious PITA to do that with a GUI tool.

Just lie to it and tell it your RAM is 8 bits wide.

Let me guess, I will have to tell it in byte, by concatenate 8 bits together ? TIA
