AR# 43042

MIG all version all FPGA DDR3 - File can not be accessed during simulation

Description

After I Define MAX_MEM in a DDR3 simulation model and run simulation, the following message is reported and simulation quits.

Failed to open file "/tmp/sim_tb_top.mem_rnk[0].mem.gen_mem[0].u_comp_ddr3.open_bank_file.0"

 

Solution

This message has been seen in 7 series MIG1.2.

Virtex-6 and Spartan-6 also have the same problem.

The issue happens because "tmp_model_dir" in the DDR3 simulation model is set to "/tmp".

In windows, "/tmp" is not a valid folder path.

Once this is changed to a valid path, no simulation issues occur.
