data2mem dump get all 0

Jump to solution

Hello,

 

I used data2mem to load data into my bit file

data2mem -bm ram.bmm -bt my_top.bit -bd ram.mem tag ram_otp -o b top_mem.bit

without error

But when i read back nothing inside all zero
data2mem -bm ram.bmm -bt top_mem.bit -d > dump_mem.txt

 

ADDRESS_SPACE ram_otp COMBINED [0x00000000:0x0000011ff]

// Otp mem
ADDRESS_RANGE RAMB36
BUS_BLOCK
i_Parsifal_Subsystem/i_Peripheral_Subsystem/i_Basic_Subsystem/i_otp_top/u_SAFMEMHV_1K/CMOS045_FU_SAFMEMHVCORE_LSOD25_C40LP_1K_inst/Fusemem_1_Fusemem_1_0_0 [35:0] PLACED = X2Y11;
END_BUS_BLOCK;
END_ADDRESS_RANGE;
END_ADDRESS_SPACE;

 

here my mem file

 

@0000000
DEADABBAFFFFFFFFFFFFFFFFFF

Hello,

 

In fact I can set data into bit file

here result dumping with data2mem :

BRAM data, Column 02, Row 11. Design instance "i_Parsifal_Subsystem/i_Peripheral_Subsystem/i_Basic_Subsystem/i_otp_top/u_SAFMEMHV_1K/CMOS045_FU_SAFMEMHVCORE_LSOD25_C40LP_1K_inst/Fusemem_1_Fusemem_1_0_0".

 00000000:   EA DB EE FF EA DA BB AF EA DF EE

 

But I see also !!! :

 

BRAM data, Column 02, Row 11. Not used in this design.

 00000000:   00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00   ................................
 

Why do I have in the same dump file twice the same column and Row  BRAM ?
