sensille | very strange. when i generate a design with 0x2000 main_ram, the main ram does not work at all (data errors: 2048/2048). when i go into the generated .v and change the size to 1024, the first 1k works. when i set it to 1025, it's broken again | 09:23 |
---|---|---|
sensille | the signals look ok in litescope. write cycle looks good to me, but the next read gives the old value | 09:24 |
sensille | when i reduce integrated_sram to 0x1000 main_ram works with 0x2000 | 09:44 |
sensille | getting closer. main_ram size must be != sram_size | 10:38 |
sensille | INFO:Xst:3227 - The RAM <Mram_sram>, combined with <Mram_main_ram>, will be implemented as a BLOCK RAM, absorbing the following register(s): <sram_adr0> | 10:38 |
sensille | and indeed, main_ram content is equal to sram content (which is a copy of some rom content at 0) | 10:39 |
sensille | i don't see from the generated .v why ISE thinks it can get away with using only one RAM instance for both sram and main_ram | 11:11 |
sensille | but i have my workaround for now | 11:18 |
