Er, this seems kind of obvious. Your transient time is only 1us (the log file shows this, and the MDL earlier shows " run tran( stop=1u, autostop='yes )"). From your ViVA plot and your revised netlist, there's no rise until 5us, so clearly it won't find a rise time after the stop time! The rise time seems very slow for a 20f load capacitance, but presumably that's your circuit. I suggest changing the stop in the MDL to (say) 20u and then it should work. Andrew
