Other Parts Discussed in Thread: LM5116
Hi Guys,
I am trying to replicate the example circuit in LM5022 datasheet, but the simulation failed every time but I can't see where went wrong. Below are the schematic, error message and error log.
Questionable use of curly braces in "b_abmgate yint 0 v={if(v(a)>{{vthresh}},{{vdd}},{{vss}})}"
Error: undefined symbol in: "if([v](a)>((vthresh)),((vdd)),((vss)))"
