generating a .vo file without the fitter

[Altera_Forum]

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

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  GPK

While that (fitter required) does seem to be the case, the quartus handbook explicitly states (from just before my post): 

 "If you want to generate a post-synthesis simulation netlist with just the cell delays, you can generate an .sdo file without running the fitter. In this case, the .sdo file includes all timing values for only the device cells. Interconnect delays are not included because fitting (placement and routing) has not been performed. To generate the post-synthesis netlist and the .sdo file, type the following commands at a command prompt:"   It wouldn't be the first time that some documentation was wrong...........

When you open :  Assignments -> EDA tool settings -> Simulation -> More EDA Netlist writer Settings   you have to set "Generate Netlist for functional simulation only"   Kind regards  GPK
