Tabular RLGC Model Syntax

.MODEL name W MODELTYPE=TABLE N=val LMODEL=l_freq_model
+ CMODEL=c_freq_model [ RMODEL=r_freq_model 
+ GMODEL=g_freq_model ]

N	Number of signal conductors.
l_freq_model	.MODEL model name for the inductance matrix.
c_freq_model	.MODEL model name for the capacitance matrix.
r_freq_model	.MODEL model name for the resistance matrix; by default, it is zero.
g_freq_model	.MODEL model name for the conductance matrix; by default, it is zero.
