Quartus II V12: .sdo files not generated or in nonexistent folder...don't know which.

Hello,

Under Quartus II V12 Build 178, 5CEBA7U19C8 Cyclone V, VHDL, I cannot get any .sdo files. SR10872286

1. under "Assignments>settings>Simulation>More EDA Netlist Writer Settings"I do not have “generate netlist for functional simulation only” selected. (this would have blocked .sdo generation)

2. I'm following

ftp://ftp.altera.com/up/pub/altera_material/10.1/tutorials/using_modelsim.pdf (ftp://ftp.altera.com/up/pub/altera_material/10.1/tutorials/using_modelsim.pdf) section 5.1

3. I search for "sdo" in all the compilation .rpt report files created during successful compilation and find nothing. Should I find anything?

4. Under Assignments>settings>Simulation I set

Output Directory: c:/Where_I_say

but this is always reset to

Output Directory: simulation/modelsim

"simulation/modelsim" is not a valid pathname and I believe that's where my .sdo file is. Definitely a bug in the template.

Has anybody generated .sdo files for Modelsim under Quartus II V12 and have any wisdom on the process?

Thanks.

    don't bet on quartus releases for gate-level support it is altera's new business strategy now. that's why i started studying other manufacturers. things that are getting chopped off with altera still exists with other manufacturers.lack of something may always be filled. but they lack things that altera has :)) so you have to decide what do you need what to loose and what to gain.problem with altera is that they think it's them or nothing. just as my zombified boss says "we have no other option! and will agree on anything that altera offers".altera does not listens to customers, it simply carries it's own business plan. no gate level simulation is a catastrophe! and to do functional simulation between CycloneV and HPS you need to buy external pack from mentor graphics. even if you try to simulate your project with CycloneIV, it won't work because Logic element architecture in Cyclone V is totally different.we are silent on too many things.what happens with altera is our fault. because we will swallow anything they throw at us.

    I'm very disappointed with Cyclone V.

    - High static power (over 3x than Cyclone IV)

    - Longer delay in the clock path

    - High compile times (Q13.1/Cyclone IV was better)

    - Poor tool support

    - no gate-level simulation

    - no auto device selected by fitter

    - ..

    Cyclone V seem worse than Cyclone IV.
