Update init data in dualport BRAM without re-run anything?

From: Mawa_fugo on 19 Mar 2010 15:01 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,

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

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

Yes, I see that execute file data2mem, look like old day command line. Guessing it's just another non-user-friendly Xilnx apps ;-) Thanks |
