(Almost) Ideal Diode Model

idealdiode.lib (LIB) – If you’re creating your circuit with the “Schematics” tool, incorporate this library into “Schematics” as follows: Select Analysis -> Library and Include Files. Type the filename idealdiode.lib in the filename box (including the path to the file), and click Add Library. If you’re creating your circuit using a standard textfile netlist, add the following lines to your file:

X1 (node 1) (node 2) diode_ideal 
.lib idealdiode.lib

idealdiode.slb (SLB) – If you’re creating your circuit with the “Schematics” tool, incorporate this symbol library into “Schematics” as follows: Select Options -> Editor Configuration. Select the Library Settings button, and then add the file idealdiode.slb. If you’re creating your circuit using a standard textfile netlist, you do NOT need this file.
