Nexxim Simulator > W-Model Transmission Line, RLCGW-RLGC Model Netlist SyntaxThe netlist format for a W-model transmission line with RLGC model type is: .MODEL modelname W MODELTYPE=RLGC N=val Lo=matrix_entries Co=matrix_entries [Ro=matrix_entries] [Go=matrix_entries] [Rs=matrix_entries] [Gd=matrix_entries] All of the input matrices are symmetrical, so the matrix_entries specify only the lower triangular matrix elements. The diagonal elements are the resistance, inductance, conductance, and capacitance (RLGC) values for each of the signal lines. For the Lo and Co matrices, diagonal elements are positive (non-zero). For the Ro, Rs, Go, and Gd matrices, diagonal elements can be positive or zero. The off-diagonal elements are mutual effect values. For the Lo and Ro matrices, off-diagonal elements can be positive or zero. For the Co, Go, and Gd matrices, off -diagonal elements can be negative or zero. RLGC models with large matrix sizes are typically written in separate files and included into the netlist with an .INCLUDE or .LIB statement. See External Files in the Netlist File Format section for details. The unit of length can be any unit as long as the L in the instance is in the same unit.
