Hi,
I am simulating the rel_0_1_beta version of t400 micro-controller project, using ModelSim6.4 and i get these errors: # ** Warning: NUMERIC_STD."=": metavalue detected, returning FALSE # Time: 0 ns Iteration: 0 Instance: /tb_t411 # ** Warning: NUMERIC_STD."=": metavalue detected, returning FALSE # Time: 0 ns Iteration: 0 Instance: /tb_t411 # ** Fatal: (vsim-7) Failed to open VHDL file "rom_41x.hex" in rb mode. # No such file or directory. (errno = ENOENT) # Time: 0 ns Iteration: 0 Process: /tb_t411/t411_b/t410_notri_b/pmem_b/rom_b/memory File: H:/t400 final/lpm_rom.vhd # Fatal error in Process memory at H:/t400 final/lpm_rom.vhd line 306 # Can anyone help me on how to remove this error? Thanks |

To resolve this issue, you'd need to generate a hex-file for the processor and place it in the current simulation directory. The hex-file contains the instruction code and is required for proper operation of the core.
Please refer to the verification tests in sw/verif/black_box for sample code that can be assembled with ASL. In sw/verif/include you'll find Makefiles for an automated build of the verification tests that generate suitable hex-files. Cheers, Arnim |
