DIsable writing netlist in binary format

Michael11

I'm implementing a design with the stylus hierarchical flow. At one point, the flow fails with

**ERROR: (IMPSER-507): Error in loading binary netlist file …/PARTITION/dbs/DoubleColumn/vbin/DoubleColumn.v.bin_7.

Which is a rather obvious error, because only the files .v.bin, .v.bin_lib, and v.bin_0 to v.bin_6 actually do exist. No _7 to be found anywhere.

Note: The database was created just minutes earlier with the very same version of Innovus (from within the generated flow template). It's rather suprising that it cannot read it's own output.

It's impossible for me to debug from here to move on with the flow. My first step would be to try and disable the use of the binary format, because a plain Verilog file seems a lot easier to handle for humans. Maybe reading that could show some obvious error.

Is there some (probably hidden) flag/option to go back to using plain text files? I'm using v21.17-s075_1,.

Thanks,
Michael

  • Hi,
    I cannot find publicly available switch to disable this. If there is a hidden flag to do this, you can only get it from Application Engineering, but they will not put it in a public forum. This would defeat the purpose of being a hidden switch.

    Also, this would be just a workaround. My suggestion is to contact Cadence support to get help.
