simulink can't map matrie to RAM
Show older comments
Hi, i worked on this function block in Simulink and failed to map this persistent matrice to RAM in HDLcoder, and there's no warning coming out of HDLcoder. Thanks in advance for your help!
Here is the function:
function rd_out = Buffer45x45(din, addr_x, addr_y, wr_en, rd_en)
persistent u_d ;
if isempty(u_d)
u_d= false(45,45);
end
reg_rd_out = rd_en && u_d(addr_x,addr_y);
u_d(addr_x,addr_y) = wr_en;
rd_out = reg_rd_out;
display(u_d(1:10, 1:10));
end
