generating a .vo file without the fitter

--- Quote Start ---

The quartus handbook shows 2 ways to generate a vo file without running the fitter:

quartus_map <project name> -c <revision name> r

quartus_sta <project name> -c <revision name> --post_map r

or

quartus_tan <project name> -c <revision name> --post_map --

zero_ic_delays r

quartus_eda <project name> -c <revision name> --simulation

--tool= <3rd party eda tool> --format=<HDL language> r

When I try the first way (quartus_sta), I get this error:

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)

When I try the second way (quartus_tan), I get this error:

Error: Device family Stratix IV is not supported by the Classic Timing Analyzer

Has anyone successfully created a vo file without running the fitter on a Stratix 4 device ?

Thanks

Hi,

the vo-file based on the netlist after Place&Route. Not only the netlist is generated also the delays of the design is extracted ( the vo-file reads the sdo file ). Therefore you have to run the fitter before you can generate the vo-file.

Your second problem is timing analyzer related. Quartus offers two timing analyzer. The old "Classic" (Quartus_tan) and the newer "TimeQuest" (Quartus_sta)Timing analyzer. StratixIV is not support by the Classic timing analyzer. I must use Timequest.

Kind regards
