Tool/software:
Hi,
I'm attempting simulation of TPS54678 pspice transient model using pspice for TI and am running into issues with the simulation getting stuck. The issue appears to be related to a convergence issue.
Is there an example pspice project for this model I could try? Alternatively, happy to share my project if you'd like to take a look.
Thanks,
Drew
Hi Werner,
I was trying to perform transient simulation of the following schematic.
I was observing that the simulation gets stuck at "Time = 49.49". This was surprising given that transient simulation is supposed to end at 10ms.
I was actually able to resolve this issue by adjusting the PTRANABSTOL and PTRANVNTOL parameters. This was suggested by the simulation output window.
INFO(ORPSIM-16594): To improve Pseudotransient Convergence and Performance, set following options to relax stabilization criteria for capacitor currents and inductor voltages: PTRANABSTOL=1e-5, PTRANVNTOL=1e-4
I actually have a power supply issue on an EVM I'm trying to debug. I'll create a separate thread to discuss this.
Thanks,
Drew
