There are no tutorials online that give usage information for the .MEASURE command in HSPICE. I need to find the saturation current, Is, of this diode using the .MEASURE. I assume the effect of series resistance Rs is neglected. Here is my code so far: *Diode Dforward 1 0 D1N4148 *DC supply Vz0 1 0 DC 0V *Model for 1N4148 Diode (from EVAL library in PSpice) .model D1N4148 D(Is=2.682n N=1.836 Rs=.5664 Ikf=44.17m Xti=3 Eg=1.11 Cjo=4p + M=.3333 Vj=.5 Fc=.5 Isr=1.565n Nr=2 Bv=100 Ibv=100u Tt=11.54n) .DC Vz0 0 5 .1 .OPTIONS POST probe .PRINT DC I(Dforward) .END If anyone can tell me what parameters to use for the .MEASURE command or direct me to a tutorial that gives many EXAMPLES (not generic command syntax info) of using the .MEASURE command, that would be appreciated.
