  1. I am trying to load my program to a Block RAM using Data2mem, after the bitfile is generated. Here are the steps: I have generated a BLOCK RAM as single port ROM with 32 bit-width and 16384 bit-depth. Then translated the design without any BMM file and looked at the PlanAhead tool to see which BRAM are used and which ramloop is assigned. There are 15 ramloop lines. There are 14 PRIM36 primitives and 1 PRIM18 primitive as shown below: BROM_instance/U0/xst_blk_mem_generator/gnativebmg.native_blk_mem_gen/valid.cstr/ramloop[0].ram.r/v5_init.ram/SP.SINGLE_PRIM18.SP **(RAMB18)** BROM_instance/U0/xst_blk_mem_generator/gnativebmg.native_blk_mem_gen/valid.cstr/ramloop[1].ram.r/v5_init.ram/SP.SINGLE_PRIM36.SP **(RAMB36_EXP)** BROM_instance/U0/xst_blk_mem_generator/gnativebmg.native_blk_mem_gen/valid.cstr/ramloop[2].ram.r/v5_init.ram/SP.SINGLE_PRIM36.SP (RAMB36_EXP) BROM_instance/U0/xst_blk_mem_generator/gnativebmg.native_blk_mem_gen/valid.cstr/ramloop[3].ram.r/v5_init.ram/SP.SINGLE_PRIM36.SP (RAMB36_EXP) ⋮⋮ BROM_instance/U0/xst_blk_mem_generator/gnativebmg.native_blk_mem_gen/valid.cstr/ramloop[14].ram.r/v5_init.ram/SP.SINGLE_PRIM36.SP (RAMB36_EXP) I wrote the following .BMM file for address the ROM from 0x0000 to 0xFFFF. and add it to the xilinx project. ADDRESS_SPACE pr_mem1 RAMB32 [0x00000000:0x0000ffff] BUS_BLOCK BROM_instance/U0/xst_blk_mem_generator/gnativebmg.native_blk_mem_gen/valid.cstr/ramloop[0].ram.r/v5_init.ram/SP.SINGLE_PRIM18.SP [31:0]; END_BUS_BLOCK; BUS_BLOCK BROM_instance/U0/xst_blk_mem_generator/gnativebmg.native_blk_mem_gen/valid.cstr/ramloop[1].ram.r/v5_init.ram/SP.SINGLE_PRIM36.SP [31:0]; END_BUS_BLOCK; BUS_BLOCK BROM_instance/U0/xst_blk_mem_generator/gnativebmg.native_blk_mem_gen/valid.cstr/ramloop[2].ram.r/v5_init.ram/SP.SINGLE_PRIM36.SP [31:0]; END_BUS_BLOCK; BUS_BLOCK BROM_instance/U0/xst_blk_mem_generator/gnativebmg.native_blk_mem_gen/valid.cstr/ramloop[3].ram.r/v5_init.ram/SP.SINGLE_PRIM36.SP [31:0]; END_BUS_BLOCK; BUS_BLOCK ⋮⋮ BROM_instance/U0/xst_blk_mem_generator/gnativebmg.native_blk_mem_gen/valid.cstr/ramloop[14].ram.r/v5_init.ram/SP.SINGLE_PRIM36.SP [31:0]; END_BUS_BLOCK; END_ADDRESS_SPACE; But when I tried to compile it again it gives me the error: ERROR:Data2MEM:29 - Inconsistent address space size in ADDRESS_SPACE 'pr_mem1'. Can you please help me out where the error is occurring? Is ramloop[xx] correctly used?
  2. Hello, Somehow I managed to put 12volts into the 5 volt input of a Virtex-II Pro FPGA board (SKU:6003-410-000) and one of the three switching psu sections is now broken. One of the surface mount ceramic caps in that section exploded and now when I give the board proper 5v power, the status led for the 1.5volt psu section does not light. I have tried powering it externally with no success and also disabling it with the jumpers. Please advise. Thank you!
