 ** NMOSFET: table generator with BSIM4 2D (Vdrain, Vgate)
+* This file may be run by 'ngspice table-generator-b4-2d.sp'

+* as function of drain and gate voltages. The simulation uses
+* the ngspice BSIM4.6.1 MOS model and Berkeley model parameters.
+* This table is an input file for the XSPICE 2D table model.
+* You have to select NMOS or PMOS by manually editing this file: currently
+* PMOS is selected. For NMOS change '*' in column 1 
+* for CSPARAM, m1, outfile, echo *table...
+* In addition you may change the step sizes vdstep vgstep vbstep in CSPARAM
+* to obtain the required resolution for the data.
+* These tables will contain pure dc data. For transient simulation you may
+* need to add some capacitors to the device model for a 'real world' simulation.
