Width and spacing list in mipt files

Hello,

 

I try to move to mipt files for xRC deck generation. First I've made the deck using tm file and the deck was calibrated successfully. Then I've created a mipt file and loaded it into the interactive environment which converted it into tm file. Everything looks the same instead of the width and spacing lists for the metal layers. In the mipt file, I can enter only the min and max values and no values in between.  I've started calibration of the tm file obtained after mipt2tm convertion and the calibration was terminated during step execute models with the following error:

Could it be due to the missing calibration steps for width and spacing? How xcalibrate calculates the models when there is no list for width and spacing and only their min and max values are in the tm file? As we know, it is very important to have a few steps for the min width and spacing which are with most signifficant parasitic capacitance and they are the most cases in a layout. Is it possible to enter steps in mipt files? I have indie tables for all metal layers but I think xcalibrate creates the models based on the values for width and spacing in the tm file.

 

I use version 2007.4.

 

Thank you in advance!
