I'm working simulating a circuit for a project and am having difficulty running the PSpice simulation.
The circuit in question is driving an IR LED using a power mosfet, and driving the mosfet with gate driver receiving a 38Khz signal from a microcontroller.
(Apologize for the plain blocks, model import wizard wasn't changing those for some reason).
What I have done is find the pspice models library files for
SFH_4715A (IR Emitting Diode)
PSMN1R0-30YLC (N channel power mosefet)
ZXGD3005 (Gate Driver)
I opened Pspice Model Editor Lite->File->Model Import Wizard->Found Model and Hit Next->Finish (Repeat for all 3 models). This created the .olb files
I then created the circuit shown above using the .olb files and performed in Capture CIS
PSpice -> New Simulation -> "enter name" -> Inherit From: "None" -> Create
I created a transient simulation to run for 1000ms, in steps of 1ms, and save data immediately. Then, from within Simulation Settings went to
Configuration Files -> Library -> "added each Pspice Model Library to the design" -> Apply -> OK
I then ran the simulation.
I am getting this output file
https://hastebin.com/oxijiyoquq.mdWith the main error being line 178 and 180
ERROR(ORPSIM-16550): Floating point computation failed during matrix solution. Possible solutions: 1)Ensure that all device parameters are in valid range. 2)Try using .options LIMIT
INTERNAL ERROR -- Overflow, Multiply
edit: I just noticed in the picture I have Fall time to be 1E-90, I fixed that but Im still having the same issue.
