MIG simulation

1) Any way to cut short the "calibration" cycle in MIG 2.3 in a modelsim simulation?   SIM_ONLY generic, with its savings of 200 us is pretty useless if I need loads of mS to run through calib, all of which is useless for simulation purposes, anyway.  

2) So, I tried to run the example_design sim; also the user_design simulation and both crash because verilog model "ddr2_model.v" is missing and is nowhere in the mig_23 design tree.  Anybody know where this can be found?

Re: MIG simulation

I believe that MIG 3.1 now reduces the calibration time when you set the SIM_ONLY generic.  Also

the file ddr2_model.v needs to come from the device manufacturer, usually Micron.  When you generate

a MIG design you are asked to accept two license agreements.  If you don't accept one of them you

don't get the chip vendor model.  Also it's possible you have chosen a chip that is not supported

by a chip vendor model.  In that case I would suggest finding the closest Micron equivalent to

your chip and get the model for that chip from Micron.
