Hello there, I'm trying to understand how magic extracts resistance to a .sim file.
I'm using the default scmos.tech of magic and i have created a rectangle (2 by 7) with polysilicium. A sim file was extracted and the output is as follows: | units: 100 tech: scmos format: MIT R a_0_n2# 84
A second sim file was extracted from a similar rectangle but twice the width that is (4 by 7) and the output is: | units: 100 tech: scmos format: MIT C a_0_n2# GND 2.9 R a_0_n2# 42
Ok if I follow the simple R =3D =FE*L /A relation where =FE is the resistivity, L : the length in this case 7 A :the area (H*W), so R =3D (=FE/H) L/W by this ratio I have =FE/H =3D 24.
Where and how magic sets =FE/H to be 24 when the scmos.tech allows
2=2E0/1.6/1.2 =B5m ? Is there a table somewhere which defines the resistance/=B5m for
- metal1,metal2,metal3
- ndiff,pdiff
- polysilicium
- ... with respect to 2.0/1.6/1.2 =B5m ?
google wasn't useful this time.
