1General (RES.-)
2.XParasitic resistance is not extrated under a sheet layer with it's corresponding res.id layer.
3
4Sheet Resistance (SR.-)
5.XCalibre now extracts deltaW by bucketing the sheet rho based on different widths.The accuracy of each bucket must be within 2% of the Sheet Rho Calc using deltaW.
6.met3Parasitic resistance is calculated for all metal3 (if metal3 exists for the specific technology)
7.met2Parasitic resistance is calculated for all metal2.
8.met1Parasitic resistance is calculated for all metal1 with the exception of varactor which follow rule SR.xcnwvc.1
9.li1Parasitic resistance is calculated for all li1.
10.poly.1Parasitic resistance on gates is calculated to the center of the gate.
11.poly.2Parasitic resistance for poly is not extracted beyond the device terminal. The device terminal for all devices but MOS is at the edge of the poly. Note: This means that parasitic resistance is not extracted for poly that is part of an LVS capacitor or LVS resistor. The LVS capacitors have poly in the model.
12.diff.1Parasitic resistance is not extracted for any diffusion regions.
13.diff.2Extract NRD/NRS for MOSFETs (except extendedDrain Fets) per the equations defined in USC-206. NRD/NRS for the n-type ESD devices must include the ntap enclosed in the source/drain ndiff hole NRD/NRS for the p-type ESD devices must include the ptap enclosed in the source/drain pdiff hole.
14.xnwvc.1Inside the Varactor device boundry (see rule PASSIVES.cnwvc.1) all layers listed in the model (m1 and below) will not have resistance extracted.
15
16contact-to-gate space (CT.-)
17.viaAll vias will have parasitic resistance extracted.
18.mconAll mcons will have parasitic resistance extracted.
19.licon.1All licons that are connected to Poly and not connected to the poly of the xhrpoly_X_X device should have resistance extracted.
20.licon.2All licons that are connnected to non-precision resistors will have resistance extracted.
21.licon.3All licons that are connected to FETs will be extracted by RCX.
22.licon.4All licons on diff of PNP/NPN will be considered part of the device model.
23.licon.5All licons on tap of PNP/NPN will be considered part of the device model.
24.licon.6All licons on non-PNP tap regions will have parasitic resistance extracted.
25.hrpoly.1All licons and mcons that are part of the hrpoly resistor will not have parasitic resitance extracted, these contacts are in the models.
26.pwres.1All licons and mcons that are part of the pwell resistor will not have parasitic resitance extracted, these contacts are in the models.
