In reply to m_r_m:
You cannot execute code created from a string. What does this not do what you want:
<file> load.data
// row -> 156 bit data // 1a0a2***aa0;
// column till 2048
reg [155:0] loc_d [0:2048];
initial begin
$readmemh("load.data", loc_d);
for(int ii =0; ii < 2048; ii++)
<PATH>.Mem[ii] = loc_d[ii][51:0];
end
