module m1;
bit [31:0] mem;
int i;
bit [31:0] cmd;
bit [31:0] addr;
initial begin
for (i=1; i<=31; i++)begin
mem = { addr[31:32-i], cmd[31-i:0] };
end
end
endmodule
when i=1
addr[31], cmd[30:0], total 32 bits used
when i=31
addr[31:1], cmd[0:0], total 32 bits used
Everytime all 32 bits have been used.
But still the code is giving compilation error saying "invalid range/invalid operand".
Could you please suggest?
Thank You
