Modelsim error on alt_dual_boot and altera_onchip_flash_block - Error: (vsim-3033): Instantiation of 'altera_onchip_flash_block' failed. The design unit was not found.

Thanks, I manage to look into it.

Since the design are from qsys, what you need to run is msim_setup.tcl. You may follow the steps below:

1) Open up the qsys files, generate the simulation model, generate -> generate hdl

2) Open modesim, cd to directory where the msim_setup.tcl

source msim_setup.tcl

3) ld

4) now the modelsim success run the simulation.

to include the tb

5) open up the msim_setup.tcl and modify the top level to spi_flash_tb

6) make sure your spi_flash_tb.vhd spi_flash under vcom

7) ld again.

Let me know if you do not get it,

Thanks

Kenny, thanks for your answer, it took me a while but I got it in the end.

Just for the sake of completion if anyone runs into the same issues:

  • The msim_setup_tcl file is located under /simulation/mentor
  • I replaced the original testbench file with my "spi_flash_tb.vhd" file on this line: "set TOP_LEVEL_NAME "spi_flash_tb" "
  • I added the following lines under vcom, at the end, in this order:

eval vcom $USER_DEFINED_VHDL_COMPILE_OPTIONS $USER_DEFINED_COMPILE_OPTIONS "$QSYS_SIMDIR/rsu_test.vhd"

eval vcom $USER_DEFINED_VHDL_COMPILE_OPTIONS $USER_DEFINED_COMPILE_OPTIONS "$QSYS_SIMDIR/spi_flash.vhd"

eval vcom $USER_DEFINED_VHDL_COMPILE_OPTIONS $USER_DEFINED_COMPILE_OPTIONS "$QSYS_SIMDIR/spi_flash_tb.vhd"

Otherwise the test simulation was missing some blocks.

  • Ran the following commands:

quit -sim

source msim_setup.tcl

ld

and it all seems to compile now. I'll test it for a while now, but it seems the issues I was having are resolved.

Thanks kindly for your support!

Cheers,

Albert F.

    Hi Albert I'm running into the same issue as you, what does your altera_onchip_flash_block.v look like? Mine is a hex file it seems...
