can anyone help me i am trying to use diode 1n4002 in my circuit but easy eda cannot simulate it. here the result of the simulation. ********************** Circuit: good* no system model for 1n4002-e3/54, you can create a model by yourself Error on line 7 : d6 0 volprobe2 1n4002-e3/54 Unable to find definition of model 1n4002 - default assumed unknown parameter (-e3) Error on line 8 : d5 volprobe2 c1_1 1n4002-e3/54 Unable to find definition of model 1n4002 - default assumed unknown parameter (-e3) Error on line 9 : d4 0 0 1n4002-e3/54 Unable to find definition of model 1n4002 - default assumed unknown parameter (-e3) Error on line 10 : d3 0 v1_1 1n4002-e3/54 Unable to find definition of model 1n4002 - default assumed unknown parameter (-e3) Error on line 11 : d2 v1_1 volprobe2 1n4002-e3/54 Unable to find definition of model 1n4002 - default assumed unknown parameter (-e3) errors/warnings in your design, please fix them if you need errors/warnings in your design, please fix them if you need.
