I have problem with synthesis. I can't find any information about this error code.

Here is the report:

I have found the code which causes this issue. But I don't know why the code causes the problem. Also, I don't know how to solve it. Here is the code:

initial

begin

$readmemb("../data/file1.txt", rom1);

$readmemb("../data/file2.txt", rom2);

end

It seems tha quartus doesn't allow me to initialize two ROMs in one verilog file. After I remove either one of the two $readmemb statement, quartus can synthesis successfully.

I have also tried used two seperate initial blocks, each block contains one $readmemb. This doesn't solve the problem.

I use the template provided by quartus to implement the two roms. Rom is inferred correctly.

How do I solve this problem? I need to initialize multiple roms and rams in my project.

Thank you!
