Generating netlist with quartus_eda

I've seen posts where people reported this error after running quartus_eda:

altera.eda.rpt:error: run the fitter (quartus_fit), followed by the timing analyzer (quartus_tan or quartus_sta), before running the eda netlist writer (quartus_eda)

The proposed solution was to generate netlist from Quartus GUI. It worked for me as well.

However, I'd like to run the whole flow - quartus_{map,fit,sta,eda} - in a command line mode using the same QSF and QPF.

Well, for some reason quartus_eda fails with aforementioned error after running map/fit/sta.

Any ideas why ?

Thanks,

Evgeni

    Generally people always use the same .qpf/.qsf for all of those modules. I just run the following:

    quartus_sh --flow compile --64bit top -c revision

    Where top is the name of the .qpf file and revision is the name of the .qsf. (Most of the time they're the same name, in which case the -c revision is unnecessary). If you have EDA enabled in your project settings(.qsf) it will run as part of this. This basically mimics hitting the compile button in Quartus GUI.

    For various reasons I need to use individual executables (that's how our build scripts are structured) rather than "quartus_sh --flow compile".

    It looks like using the following parameters to quartus_eda:

    --read_settings_files=off --write_settings_files=off <proj> -c <version> --format=verilog --tool=modelsim --simulation=on

    fixes the problem.

    GUI flow was using the command:

    quartus_eda --read_settings_files=off --write_settings_files=off <proj> -c <version>

    So by adding format, tool and simulation parameters to command line, even though the QSF already contained those options, made it work.

    That sounds like a bug.

    I'm working with an older 9.1sp2 Quartus version. Maybe there is a bug there and I should try the latest 11.1.
