How to read ITF file to find the process technology

The MinWidth of POLY layer represent the process technology.

See following example:

============

$$/*     layer  min_width       min_space*/

$$      ALMETAL 2       2

$$      TGM     0.4     0.4

$$      M5      0.063   0.063

$$      M4      0.063   0.063

$$      M3      0.063   0.063

$$      M2      0.063   0.063

$$      M1      0.063   0.063

$$      GC      0.04    0.09

 

 

$CONDUCTOR  GC              { THICKNESS=0.080000 WMIN=0.040000 SMIN=0.090000 RPSQ=17.000000 }

=============

This is a 40nm(cutting edge from 45nm).
