I encountered some issues while simulating the transient characteristics of a device using Mixed Mode. After executing the following codes, an error message "Simulator has unexpectedly exited with status 0" is reported. The code is here:
.begin
Vdd 1 0 5
Vin 3 0 0 pluse 0 5 0 50ps 50ps 1000ps 10
An 3=gate 0=source 1=drain 0=n_substrate width=100 infile=n_HEMT2.str
.nodeset V(1)=0 V(3)=0
.options print noshift
.numeric lte=1e-3 dtmin=1e-15 imaxdc=50
.load infile=inv
.log outfile=n_test
.tran 0.001ps 3ns
.end
Could someone give me some suggestions?
