post PAR simulation using quartusII and arria10 family

[Altera_Forum]

hi, 

 i am working on quartusII v15.0 and arria10 family of fpgas. my target simulation tool is either Modelsim-altera or VCS-MX. I am trying to do post PAR simulation using either of these tools (bhv sim is OK). i am facing 2 issues when i try to do this -   issue1) when I do a design compile, the .vo files for the respective simulators is created, however i dont see a .sdo or .sdf file being created anywhere? also, in the eda netlist writer settings, the option to "generate netlist for only functional simulation is turned off". so as per some other threads, the .sdo/.sdf file should be generated. but it's still not happening.  please let me know how to create a .sdo file for post PAR sim? Or where i should look for it?  issue2) when i do run the simulation with just the .vo file, i get an error saying - twentynm_io_obuf module unresolved.  i have compiled the verilog libs for the target fpga and i am specifying the target path (i used the tools -> simulation library compiler option to do this and compile was good).  please let me know how i can generate or point to the twentynm_io_obuf modules?  currently, my library compilation output has the following - +cli+1 -line -timescale=1ps/1ps -sverilog +verilog2001ext+.v  +incdir+/tools/altera/quartusII_15.0.0.145/quartus/eda/sim_lib  /tools/altera/quartusII_15.0.0.145/quartus/eda/sim_lib/altera_primitives.v  /tools/altera/quartusII_15.0.0.145/quartus/eda/sim_lib/220model.v  /tools/altera/quartusII_15.0.0.145/quartus/eda/sim_lib/sgate.v  /tools/altera/quartusII_15.0.0.145/quartus/eda/sim_lib/altera_mf.v    -lca /tools/altera/quartusII_15.0.0.145/quartus/eda/sim_lib/altera_lnsim.sv  /tools/altera/quartusII_15.0.0.145/quartus/eda/sim_lib/twentynm_atoms.v  /tools/altera/quartusII_15.0.0.145/quartus/eda/sim_lib/synopsys/twentynm_atoms_ncrypt.v  /tools/altera/quartusII_15.0.0.145/quartus/eda/sim_lib/synopsys/twentynm_hssi_atoms_ncrypt.v  /tools/altera/quartusII_15.0.0.145/quartus/eda/sim_lib/twentynm_hssi_atoms.v  /tools/altera/quartusII_15.0.0.145/quartus/eda/sim_lib/synopsys/twentynm_hip_atoms_ncrypt.v  /tools/altera/quartusII_15.0.0.145/quartus/eda/sim_lib/twentynm_hip_atoms.v  +incdir+/tools/altera/quartusII_15.0.0.145/quartus/eda/sim_lib  am i missing something? please let me know ...  z.
